Planning

Why MAS?

MAS enables every NetScaler administrator to achieve the following:

  • Alert notifications – Receive email alerts whenever something goes down. For example, if a Load Balancing service goes down, you can receive an email alert.
    • MAS can email you for any Major SNMP trap produced by any NetScaler appliance.
  • Automatically backup all NetScaler instances.
    • MAS can even transfer the backups to an external system, which is then backed up by a normal backup tool.
  • SSL Certificate Expiration – Alert you when SSL certificates are about to expire.
    • Show you all SSL certificates across all NetScaler appliances.
  • Configuration Record and Play – Use the Configuration Recorder to configure one NetScaler appliance, and then push out the same configuration changes to additional appliances. This is the easiest method of managing NetScaler appliances in multiple datacenters.
  • AppFlow Reporting – Receive ICA AppFlow traffic from NetScaler and show it in graphs.
    • Integrate MAS with Citrix Director so Help Desk can see the AppFlow data.

Everything listed above is completely free, so there’s no reason not to deploy MAS.

MAS Overview

For an overview of MAS, see Citrix’s YouTube video Citrix NetScaler MAS: Application visibility and control in the cloud.

Cloud vs on-prem

MAS is available both on-premises, and as a Cloud Service. For the Cloud Service, you import a MAS Agent appliance to an on-prem hypervisor, or deploy a MAS Agent to AWS or Azure. The MAS Agent is the broker between the Cloud Service and the on-prem (or cloud hosted) NetScaler appliances. For more info on the MAS Cloud Service, see the following:

The rest of this article focuses on the on-premises version, but much of it also applies to the Cloud Service.

On-premises MAS Licensing:

  • Instance management is free (unlimited). This includes Configuration Jobs, Instance Backups, Network Functions/Reporting. Basically everything in the Networks node is free.
  • Analytics and Application monitoring are free for up to 30 Virtual Servers (Load Balancing, NetScaler Gateway, Content Switching, etc.).
    • Beyond 30 Virtual Servers, licenses can be purchased in 100 Virtual Server packs. See NetScaler MAS Licensing at Citrix Docs.
    • You can control assignment of licenses to Virtual Servers.

MAS version – The version/build of NetScaler MAS must be the same or newer than the version/build of the NetScaler appliances being monitored. MAS 12.1 can monitor 12.0 and older appliances.

HDX Insight

HDX Insight Requirements (aka AppFlow Analytics for Citrix ICA traffic):

  • Your NetScaler appliance must be running Enterprise Edition or Platinum Edition.
  • NetScaler must be 10.1 or newer.
  • HDX Insight works with the following Receivers:
    • Receiver for Windows must be 3.4 or newer.
    • Receiver for Mac must be 11.8 or newer.
    • Receiver for Linux must be 13 or newer.
    • Notice no mobile Receivers. See the Citrix Receiver Feature Matrix for the latest details.
  • For ICA Session Reliability with AppFlow: NetScaler 10.5 build 54 and newer.
    • For ICA Session Reliability, AppFlow, and NetScaler High Availability: NetScaler 11.1 build 49 and newer.
  • AppFlow statistics are only generated when ICA traffic flows through a NetScaler. Internally, when a user clicks an icon from StoreFront, an ICA connection is established directly from Receiver to the VDA, thus bypassing the internal NetScaler. Here are some methods of getting ICA traffic to flow through an internal NetScaler:
  • For ICA round trip time calculations, in a Citrix Policy, enable the following settings:
    • ICA > End User Monitoring > ICA Round Trip Calculation
    • ICA > End User Monitoring > ICA Round Trip Calculation Interval
    • ICA > End User Monitoring > ICA Round Trip Calculation for Idle Connections
  • Citrix CTX215130 HDX Insight Diagnostics and Troubleshooting Guide contains the following contents:
    • Introduction
    • Prerequisites for Configuring HDX Insight
    • Troubleshooting
      • Issues Related to ICA parsing
      • Error Counter details
    • Checklist before Contacting Citrix Technical Support
    • Information to collect before Contacting Citrix Technical support
    • Known Issues

Citrix CTX204274 How ICA RTT is calculated on NetScaler Insight: ICA RTT constitutes the actual application delay. ICA_RTT = 1 + 2 + 3 + 4 +5 +6:

  1. Client OS introduced delay
  2. Client to NS introduced network delay (Wan Latency)
  3. NS introduced delay in processing client to NS traffic (Client Side Device Latency)
  4. NS introduced delay in processing NS to Server (XA/XD) traffic (Server Side Device Latency)
  5. NS to Server network delay (DC Latency)
  6. Server (XA/XD) OS introduced delay (Host Delay)

Multi-Datacenter Deployment Architecture

In a main datacenter, import two NetScaler MAS appliances into the same subnet and configure them as an HA pair with a Floating IP address.

In a DR datacenter, import a MAS appliance, and configure it to replicate with the main datacenter.

For NetScaler appliances in additional datacenters, import two MAS Agent appliances into each datacenter, and configure them as remote agents to the main datacenter. Two MAS Agents per datacenter enables HA. The virtual appliance for MAS Agent is different than the normal MAS appliance.

Import MAS Appliance

To import a MAS Appliance into vSphere, do the following. The same process is used for all types of MAS appliances in all datacenters.

  1. Download NetScaler MAS for ESX, and then extract the .zip file.
  2. In vSphere Web Client, right-click a cluster, and click Deploy OVF Template.
  3. In the Select an OVF Template page, select Local file, and browse to the NetScaler MAS .ovf files. If vCenter 6.5+, select all three files. Click Next.

  4. In the Select name and folder page, enter a name for the virtual machine, and select an inventory folder. Then click Next.
  5. In the Select a resource page, select a cluster or resource pool, and click Next.
  6. In the Review details page, click Next.
  7. In the Select storage page, select a datastore. Due to high IOPS, SSD or Flash is recommended.
  8. Change the virtual disk format to Thin Provision. Click Next.
  9. In the Select networks page, choose a valid port group, and click Finish.
  10. In the Ready to Complete page, click Finish.
  11. Before powering on the appliance, you can review its specs. Right-click the virtual machine, and click Edit Settings.
  12. Review the specs. Citrix Docs VMware ESXi Hardware Requirements has recommended specs.
  13. Citrix Docs How to Attach an Additional Disk to NetScaler MAS says that an additional disk must be added before initial deployment.
    • Use the MAS storage calculator to determine the recommended size of the disk. Ask your Citrix Partner for the tool.
    • The new disk must be larger than 120 GB.
    • In MAS 12.1, the new disk can be larger than 2 TB.
    • In MAS 12.1, the new disk can be grown later, and /mps/DiskPartitionTool.py can resize the partition, but only up to 2 TB. If you need more than 2 TB, the initial disk should be larger than 2 TB.
  14. Power on the Virtual Machine.

Appliance IP Address Configuration

  1. Open the console of the virtual machine.
  2. Configure an IP address.
  3. Enter 7 when done.

  5. Enter the NSIP address of a NetScaler appliance.
  6. Click the pencil next to ns_nsroot_profile.
  7. Type in the nsroot password, and then scroll down.
  8. The NetScaler Profile defaults to using https for instance communication. You can change it by unchecking Use global settings for NetScaler communication.
  9. Enter an SNMP v3 Security Name that NetScaler MAS will configure on the appliance.
  10. Click OK.
  11. Select the Site for the instance. You can click the plus icon to create a Site.
  12. For remote sites, you can optionally choose a MAS Agent.
  13. Then click OK to add the instance.
  14. A progress window will appear.
  15. You can add more instances, or just click Finish.
  16. To add more instances later, click the top left hamburger icon, go to Networks > Instances > NetScaler ADC. On the right, select a tab (e.g. MPX), and then click Add.

  17. To edit, or create new Admin Profiles, go to Networks > Instances > NetScaler ADC, and on the right is a Profiles button.

NetScaler SDX

  1. At Networks > Instances > NetScaler ADC, on the SDX tab, you can click Add to discover a SDX appliance, and all VPXs on that SDX appliance. You don’t have to discover the VPXs separately.
  2. In the Add NetScaler SDX page, click the pencil icon next to the Profile Name drop-down to edit nssdx_default_profile. Or you can click the plus icon to create a new SDX Profile. Note: SDX profiles are different than VPX profiles.
  3. Enter the credentials for the SDX SVM Management Service.
  4. For NetScaler Profile, select an admin profile that has nsroot credentials for the VPX instances. After the VPXs are discovered, MAS uses the NetScaler Profile to login to each VPX. If you don’t have a VPX Admin Profile in your drop-down list, click the plus icon. Note: You can only select one NetScaler Profile. If each VPX instance has different nsroot credentials, you can fix it after SDX discovery has been performed. The NetScaler Profile is different than the SDX Profile.

    1. In the Create NetScaler Profile page, enter the nsroot credentials for the VPX instances, and then scroll down.
    2. Enter a new SNMP Security Name or Community String.
    3. Then click Create.

  7. Back in the Add NetScaler SDX page, select a Site, and optionally an Agent.
  8. Click OK to start discovery.
  9. After discovery is complete, switch to the NetScaler VPX tab. You should automatically see the VPX instances.
  10. To specify the nsroot credentials for a VPX, right-click the VPX, and click Edit.

    1. In the Modify NetScaler VPX page, either select an existing Profile Name, or click the plus icon to create a new one. Click OK when done. It should start rediscovery automatically.
  11. After fixing the nsroot credentials, right-click the VPX instance, and click Configure SNMP. MAS will configure the VPX to send SNMP Traps to MAS.

Instance management

  • REST API proxy – NetScaler MAS can function as a REST API proxy server for its managed instances. Instead of sending API requests directly to the managed instances, REST API clients can send the API requests to NetScaler MAS. See Citrix CTX228449 NetScaler MAS as an API Proxy Server
  • NetScaler VPX Check-In/Check-Out Licensing – You can allocate VPX licenses to NetScaler VPX instances on demand from NetScaler MAS. The Licenses are stored and managed by NetScaler MAS, which has a licensing framework that provides scalable and automated license provisioning. A NetScaler VPX instance can check out the license from the NetScaler MAS when a NetScaler VPX instance is provisioned, or check back in its license to NetScaler MAS when an instance is removed or destroyed. See Citrix CTX228451 NetScaler VPX Check-In/Check-Out Licensing with NMAS

Licenses

Virtual Server License Packs

Without licenses, you can enable analytics features on only 30 Virtual Servers. You can install additional licenses in 100 Virtual Server packs. More info at NetScaler MAS Licensing at Citrix Docs.

  1. On the left, go to Networks > Licenses.
  2. On the right, notice the Host ID.
  3. At mycitrix.com, allocate your NetScaler MAS licenses to this Host ID.
  4. Then use the Browse button to upload the allocated license file.
  5. Click Finish after uploading the license file to apply it.
  6. The License Expiry Information section shows you the number of installed licenses and when they expire.
  7. You can use the Notification Settings section to email you when licenses are almost fully consumed or about to expire.
  8. If you don’t have an Email server setup yet, click the plus icon to create one.

Allocate licenses to Virtual Servers

You can manually unassign a MAS Virtual Server license and reassign it to a different Virtual Server.

  1. Go to Networks> Licenses > System Licenses to see the number of currently installed licenses, and the number of managed virtual servers.
  2. By default, Auto-select Virtual Servers is enabled. If you disable this setting, then the Click to select button appears.
  3. Click the Click to select button.
  4. The top right shows you the number of licensed Virtual Servers.
  5. In the left, select the type of Virtual Server you want to unlicense or license.
  6. On the Licensed tab, select one or more Virtual Servers, and click the Unlicense button. This returns licenses to the pool.
  7. Switch to the Unlicensed tab.
  8. Select a Virtual Server you want to license, and then click the License button.
  9. Click the blue back arrow when done.

Enable AppFlow / Insight

  1. Go to Networks > Instances > NetScaler ADC. On the right, switch to one of the instance type tabs (e.g. VPX).
  2. Select an instance, open the Select Action menu, and click Configure Analytics.
  3. At the top of the page are boxes you can check.
  4. In the Application List page, with Load Balancing selected in the View list, select your StoreFront load balancer, and then click Enable AppFlow. If you don’t see your Virtual Server in this list, then you need to assign a license.
  5. In the Enable AppFlow window, do the following:
    1. In the larger Expression box, type in true.
    2. For newer NetScaler appliances, change the Transport Mode selection to Logstream instead of IPFIX. Notice the firewall requirement for TCP port 5557.
    3. Select Web Insight.
    4. If App Firewall is enabled on the vServer, then also select Security Insight.
    5. Client Side Measurement injects JavaScript in HTTP responses to measure page load times and can sometimes cause problems in Receiver.
  6. Click OK.
  7. Use the View drop-down to select VPN.
  8. Right-click a NetScaler Gateway Virtual Server, and click Enable AppFlow.
  9. In the Enable AppFlow window, do the following:
    1. In the Select Expression drop-down, select true.
    2. For newer NetScaler appliances, change the Transport Mode to Logstream. Notice the firewall warning.
    3. Select both ICA and HTTP. The HTTP option is for Gateway Insight.
    4. The TCP option is for the second appliance in double-hop ICA. If you need double-hop, then you’ll also need to run set appflow param -connectionChaining ENABLED on both appliances. See Enabling Data Collection for NetScaler Gateway Appliances Deployed in Double-Hop Mode at Citrix Docs for more information.
  10. Click OK.
  11. By default, with AppFlow enabled, if a NetScaler High Availability pair fails over, all Citrix connections will drop, and users must reconnect manually. NetScaler 11.1 build 49 adds a new feature to replicate Session Reliability state between both HA nodes.
    1. From Session Reliability on NetScaler High Availability Pair at Citrix Docs: Enabling this feature will result in increased bandwidth consumption, which is due to ICA compression being turned off by the feature, and the extra traffic between the primary and secondary nodes to keep them in sync.
    2. On a NetScaler 11.1 build 49 and newer appliance, go to System > Settings.
    3. On the right, in the Settings section, click Change ICA Parameters.
    4. Check the box next to Session Reliability on HA Failover, and click OK.
  12. In a NetScaler 12 instance, at System > AppFlow > Collectors, you can see if the Collector (MAS) is up or not. However, NetScaler uses SNIP to verify connectivity, but AppFlow is sent using NSIP, so being DOWN doesn’t necessarily mean that AppFlow isn’t working. Citrix CTX227438 After NetScaler Upgrade to Release 12.0 State of AppFlow Collector Shows as DOWN.

  13. AppFlow for ICA (HDX Insight) information can be viewed in NetScaler MAS under the Analytics > HDX Insight node.

Director Integration

Integrating NetScaler MAS with Director adds Network tabs to Director’s Trends and Session Details views. Citrix Blog Post Configure Director with Netscaler Management & Analytics System (MAS)

Requirements:

  • XenApp/XenDesktop must be licensed for Platinum Edition. This is only required for the Director integration. Without Platinum, you can still access the HDX Insight data by going visiting the NetScaler MAS website.
  • Director must be 7.11 or newer for NetScaler MAS support.

To link Citrix Director with NetScaler MAS:

  1. On the Director server, run C:\inetpub\wwwroot\Director\tools\DirectorConfig.exe /confignetscaler.
  2. Enter the NetScaler MAS nsroot credentials.
  3. If HTTPS Connection (recommended), the NetScaler MAS certificate must be valid and trusted by both the Director Server and the Director user’s browser.
  4. Enter 1 for NetScaler MAS.
  5. Do this on both Director servers.

Use NetScaler MAS

Networks

Everything under the Networks node is free.

At Networks > Instances, select an instance, and view its Dashboard.

MAS 12.1 adds a series of tabs to the Instance Dashboard.

Backups are available by selecting an instance, and clicking Backup/Restore.

Networks > Network Reporting lets you create Dashboards where you can view Instance performance data.

Networks > Network Reporting > Thresholds lets you create thresholds when counters cross a threshold. For example, you might want a notification when Throughput gets close to the licensed limit.

Configuration Record and Play

Use MAS to record a configuration change on one instance, and push to other instances.

  1. Go to Networks > Configuration Jobs.
  2. On the right, click Create Job.
  3. Change the Configuration Source drop-down to Record and Play.
  4. Change the Source Instance drop-down to the instance you want to record.
  5. Click Record.
  6. MAS opens the instance GUI. Make changes as desired.
  7. When done, go back to MAS, and click Stop.
  8. MAS retrieves the changed config.
  9. On the left, you’ll see the changed commands. Drag them to the right.
  10. On the right, you can change instance-specific values to variables by simply highlighting the values. This allows you to change the values for each instance you push this config to.
  11. Proceed through the rest of the Configuration Job wizard like normal. You’ll select instances, specify variable values for each instance, and schedule the job.

Dave Brett Automating Your Netscaler 11.1 Vserver Config Using Netscaler Management and Analytics System uses a Configuration Job to deploy StoreFront load balancing configuration to an instance.

Analytics and Applications

This functionality requires Virtual Server licenses, which can come from your built-in 30 free licenses.

The AppFlow Analysis tools (e.g. HDX Insight) are located under the Analytics node. See Viewing HDX Insight Reports and Metrics at Citrix Docs.

Applications > Dashboard automatically includes all licensed vServers in the Others section. On the top middle, click Define Custom App to group vServers together into an application. The grouped vServers are removed from the Others list.

Applications > Configurations > Stylebooks lets you use Stylebooks to create new NetScaler configurations.

There are built-in Stylebooks for Exchange, SharePoint, Oracle, ADFS, etc. Or you can create your own Stylebook and use it to create NetScaler configurations. For details, see Stylebooks at Citrix Docs.

The Applications Node has quite a bit of functionality. See Application Analytics and Management at Citrix Docs for details.

Change Log

Director Licensing – Platinum Edition

See the XenApp and XenDesktop Feature Matrix. Scroll down to Director Platinum Edition for the list of Director features that require Platinum Edition licensing.

  • Up to a year’s worth of performance data that provides a comprehensive view of capacity trends
  • Proactive notification and alerting including SNMP integration
  • SCOM alerts
  • Desktop and server OS usage reporting
  • Create customized reports
  • Reboot warnings
  • NetScaler MAS integration – HDX Insight
  • Override control over roaming sessions

See Citrix Docs Feature compatibility matrix for a list of which Director feature came with each version, and the licensing Edition needed for each feature.


Install/Upgrade Director 7.18 on Standalone Server

Current Release vs LTSR – Director 7.18 is a Current Release, which is only supported for 6 months from the release date, and you are expected to upgrade it every 3-6 months. If you prefer a release with a longer support cycle, see Director 7.15 LTSR.

Install on Delivery Controller? – The XenDesktop Delivery Controller metainstaller has an option to install Director on the Delivery Controller machine. Or you can install Director on separate, dedicated machines.

  • If Director will connect to multiple sites/farms, then install Director on its own servers.
  • For small environments, it might be OK to install Director on the Delivery Controller machines. Otherwise, Director is usually installed on separate machines.

Director and Delivery Controller versions – There’s no point in upgrading to Director 7.18 if your Delivery Controllers are not also 7.18. Director will inform you if your Delivery Controllers are not the same version as Director.

Installation guidance – For Director installation guidance, see the following:

Scripted install – To install and configure Director using a script, see Dennis Span Citrix Director unattended installation with PowerShell.

Manual installation – To install Director manually:

  1. Start with running AutoSelect.exe from the XenApp/XenDesktop 7.18 ISO.
  2. In the Extend Deployment section, on the bottom left, click Citrix Director.
  3. In the Licensing Agreement page, select I have read, understand, and accept the terms, and click Next.
  4. In the Core Components page, click Next.
  5. In the Delivery Controller page, it will ask you for the location of one Controller in the farm. Only enter one Controller per farm. If you have multiple Director servers, each Director server can point to a different Controller in the farm. From Citrix Docs: Director automatically discovers all other Controllers in the same Site and falls back to those other Controllers if the Controller you specified fails. Click Test Connection, and then click Add.
  6. You can optionally force SSL/TLS for the Monitoring service by following the instructions at Data Access Security at Citrix Developer Documentation. Also see CTX224433 Error: “Cannot Retrieve Data” on Citrix Director Dashboard After Securing OData Interface Through TLS.  💡
  7. In the Features page, click Next.
  8. In the Firewall page, click Next.
  9. In the Summary page, click Install.
  10. A machine restart will probably be needed.
  11. After the restart, login.
    1. If you see a Locate ‘XenDesktop’ installation media window, don’t click anything.
    2. Mount the XenApp_and_XenDesktop_718.iso.
    3. Go back to the Locate media window. On the left, expand This PC and click DVD Drive. Then click Select Folder.
    4. Installation will resume.
  12. In the Finish page, click Finish.
  13. In IIS Manager, go to Default Web Site > Director > Application Settings, find Service.AutoDiscoveryAddresses, and make sure it points to one Controller in the farm, and not to localhost. From Citrix Docs: Director automatically discovers all other Controllers in the same Site and falls back to those other Controllers if the Controller you specified fails.
  14. If you built multiple Director servers, use NetScaler to load balance them.
  15. If you are upgrading Director, run C:\inetpub\wwwroot\Director\tools\DirectorConfig.exe /upgrade to complete the upgrade process.
  16. For info on the new monitoring features in Director 7.18 and older, see Use Director below.

Director Default Webpage

From CTX223907 How to Make Director the Default Page within IIS: If Director is installed on a standalone server, do the following to set /Director as the default path.

  1. Open Notepad elevated (as administrator) and paste the following text:
    <script type="text/javascript">
    <!--
    window.location="https://director.corp.com/Director";
    // -->
    </script>
  2. Adjust the window.location line to match your FQDN.
  3. Select File > Save As and browse to the IIS folder, by default C:\inetpub\wwwroot is the IIS folder.
  4. Select the Save as type to All types.
  5. Type a file name with an html extension, and select Save.
  6. Open IIS Manager.
  7. Select the SERVERNAME node (top-level), and double-click Default Document, as shown in the following screen shot:
  8. On the right, click Add…,
  9. Enter the file name of the .html file provided in Step 5.
  10. Ensure the .html file is located at the top of the list, as shown in the following screen shot:

Director Spinning Circle

If after login to Director the spinning circle doesn’t go away…

Do the following to fix it:

  1. Edit the file C:\inetpub\wwwroot\Director\web.config using an elevated text editor.
  2. Search for <serviceHostingEnvironment (line 273).
  3. Add the following attribute:
    multipleSiteBindingsEnabled="true"

Also see CTX202564 Citrix Director Becomes Unresponsive after Submitting the Credentials when IIS X-Frame-Options is enabled

Director Domain Field

On the Director servers, locate and edit the ‘LogOn.aspx’ file. By default you can find it at C:\inetpub\wwwroot\Director\Logon.aspx

In line 450 you will have the following. To find the line, search for ID=”Domain”.

<asp:TextBox ID="Domain" runat="server" CssClass="text-box" onfocus="showIndicator(this);" onblur="hideIndicator(this);"></asp:TextBox>

In the ID=”Domain” element, insert a Text attribute and set it to your domain name. Don’t change or add any other attributes. Save the file.

<asp:TextBox ID="Domain" runat="server" Text="Corp" CssClass="text-box" onfocus="showIndicator(this);" onblur="hideIndicator(this);"></asp:TextBox>

This will prepopulate the domain field text box with your domain name and still allow the user to change it, if that should be required. Note: this only seems to work if Single Sign-on is disabled.

Citrix CTX227936 How to hide the domain from Director Logon Page:  💡

  1. Edit the file C:\inetpub\wwwroot\Director\LogOn.aspx using an elevated text editor.
  2. Locate the tag which starts with: <asp:Label ID="DomainLabel"
  3. Immediately prior to that label, locate the tag: <div class='label eight'>
  4. Add the following before <div class=’label eight’>: <div style='display:none'>
  5. In between “</asp:Textbox> <br />” add the following: </div>

Director Tweaks

Session timeout

By default the idle time session limit of the Director is 245 min. If you wish to change the timeout, here is how to do it.

  1. Log on to the Director Server as an administrator
  2. Open the ‘IIS Manager’
  3. Browse to ‘SitesDefault Web SiteDirector’ in the left hand pane.
  4. Open ‘Session State’ in the right hand pane
  5. Change the ‘Time-out (in minutes)’ value under ‘Cookie Settings’
  6. Click ‘Apply’ in the Actions list

SSL Check

From http://euc.consulting/blog/citrix-desktop-director-2-1: If you are not securing Director with an SSL certificate you will get this error at the logon screen.

To stop this:

  1. Log on to the Director Server as an administrator
  2. Open the ‘IIS Manager’
  3. Browse to ‘SitesDefault Web SiteDirector’ in the left hand pane.
  4. Open ‘Application Settings’ in the right hand pane
  5. Set UI.EnableSslCheck to false.

Disable Activity Manager

From Disable the visibility of running applications in the Activity Manager in Advanced Configuration at Citrix Docs: By default, the Activity Manager in Director displays a list of all the running applications and the Windows description in the title bars of any open applications for the user’s session. This information can be viewed by all administrators that have access to the Activity Manager feature in Director. For Delegated Administrator roles, this includes Full administrator, Delivery Group administrator, and Help Desk Administrator.

To protect the privacy of users and the applications they are running, you can disable the Applications tab from listing running applications.

  • On the VDA, modify the registry key located at HKLM\Software\Citrix\Director\TaskManagerDataDisplayed. By default, the key is set to 1. Change the value to 0, which means the information will not be displayed in the Activity Manager.
  • On the server with Director installed, modify the setting that controls the visibility of running applications. By default, the value is true, which allows visibility of running applications in the Applications Change the value to false, which disables visibility. This option affects only the Activity Manager in Director, not the VDA. Modify the value of the following setting:
    UI.TaskManager.EnableApplications = false

Large Active Directory / Multiple Forests

From CTX133013 Desktop Director User Account Search Process is Slow or Fails: By default, all the Global Catalogs for the Active Directory Forest are searched using Lightweight Directory Access Protocol (LDAP). In a large Active Directory environment, this query can take some time or even time out.

If multiple forests, see Citrix Blog Post Using Citrix Director in a MultiForest Environment.

  1. In Information Server (IIS) Management, under the Desktop Director site, select Application Settings and add a new value called Connector.ActiveDirectory.ForestSearch. Set it to False. This disables searching any domain except the user’s domain and the server’s domain.
  2. To search more domains, add the searchable domain or domains in the Connector.ActiveDirectory.Domains field.

Site Groups

From Citrix Blog Post Citrix Director 7.6 Deep-Dive Part 4: Troubleshooting Machines:

If there are a large number of machines, the Director administrator can now configure site groups to perform machine search so that they can narrow down searching for the machine inside a site group. The site groups can be created on the Director server by running the configuration tool via command line by running the command:

C:\inetpub\wwwroot\Director\tools\DirectorConfig.exe /createsitegroups

Then provide a site group name and IP address of the delivery controller of the site to create the site group.

Director Configuration Script

Johan Greefkes at Script for configuring Director at Citrix Discussions was kind enough to provide a script that does the following:

  • Sets the XenDesktop Controllers that Director communicates with
  • Disables SSL Check
  • Sets Logon.aspx file to default to a domain name
  • Adds a footer that displays the name of the Director server

Director – Saved Filters

From Scott Osborne and Jarian Gibson at Citrix Discussions: In Director, you can create a filter and save it.

The saved filter is then accessible from the Filters menu structure.

The saved filters are stored on each Director server at C:\Inetpub\wwwroot\Director\UserData. Each user has their own saved filters. The saved filters are not replicated across Director servers.

You can instead configure multiple Director servers to store the filters on a shared UNC path: (h/t CTP Jarian Gibson)

  1. Create and share a folder (e.g. DirectorData).
  2. The Director server computer accounts need Modify permission to the share.
  3. On each Director server, run IIS Manager.
  4. Go to Sites > Default Web Site > Director. In the middle, double-click Application Settings.
  5. Change the Service.UserSettingsPath setting to the UNC path of the new share.
  6. Repeat this on other load balanced Director servers.

Director and HDX Insight

You can connect Director to NetScaler Management & Analytics System (NetScaler MAS) or Citrix Insight Center to add Network tabs to Director’s Trends and Machine Details views. Citrix Blog Post Configure Director with NetScaler Management & Analytics System (MAS).

Director and Self-Service Password Reset (SSPR)

If you have XenApp/XenDesktop Platinum Edition, it’s possible to install SSPR on the Director server. See George Spiers Citrix Self-Service Password Reset for a detailed implementation guide.

However this might break Director, and all you will see is a spinning circle.

To fix it, in IIS Manager (inetmgr), edit the bindings of the Default Web Site, and Remove the HTTP 8080 binding. Or implement the multisitebinding fix.

More info at Citrix Discussions Installing SSPR 1.0 appears to have broken Director 7.11 on same server.

Director Grooming

If XenDesktop is not Platinum Edition, then all historical Director data is groomed at 30 days.

For XenDesktop/XenApp Platinum Edition, by default, most of the historical Director data is groomed at 90 days. This can be adjusted up to 367 days by running a PowerShell cmdlet.

  1. On a XenDesktop Delivery Controller, run PowerShell and run asnp Citrix.*

  2. Run Get-MonitorConfiguration to see the current grooming settings.
  3. Run Set-MonitorConfiguration to change the grooming settings.

More details on Monitor Service data aggregation and retention can be found at Data granularity and retention at Citrix Docs.  💡

Director Single Sign-on

You can configure Director to support Integrated Windows Authentication (Single Sign-on). Note: there seem to be issues when not connecting from the local machine or when connecting through a load balancer.

  1. Run IIS Manager. You can launch it from Server Manager (Tools menu), or from the Start Menu, or by running inetmgr.
  2. On the left, expand Sites, expand Default Web Site, and click Director.
  3. In the middle, double-click Authentication in the IIS section.
  4. Right-click Windows Authentication, and Enable it.
  5. Right-click Anonymous Authentication, and Disable it.
  6. Pass-through auth won’t work from another computer until you set the http SPN for the Director server. See Director 7.7 Windows Authentication not working with NS LB at Citrix Discussions.
  7. If Director is not installed on a Controller, then you’ll need to configure Kerberos delegation.
  8. If you are load balancing Director then additional config is required. See Director 7.7 Windows Authentication not working with NS LB at Citrix Discussions for more info.
    1. The FQDN for Director load balancing should be different than the FQDN for StoreFront load balancing.
    2. Create an AD service account that will be used as the Director’s ApplicationPoolIdentity.
    3. Create SPN and link it to the service account.
      setspn -S http/loadbalanced_URL domain\user
    4. Trust the user account for delegation to any service (Kerberos only) (trust the Director servers for delegation is not necessary in this case). You have to create the SPN before you can do this step.
    5. In IIS manager, on the Application Pools (Director), specify the Identity as user we have created in step 1.
    6. In IIS manager, expand Default Web Site, select Director, and open the Configuration Editor (bottom of the middle pane).
    7. Use the drop-down to navigate to the following section: system.webServer/security/authentication/windowsAuthentication
    8. Set useAppPoolCredentials = True, and useKernelMode = False. Click Apply on the top right.

  9. When you connect to Director you will be automatically logged in. You can change the login account by first logging off.
  10. Then change the drop-down to User credentials.

Director – Multiple XenDesktop Sites

  1. Run IIS Manager. You can launch it from Server Manager (Tools menu) or from the Start Menu, or by running inetmgr.
  2. On the left, expand Sites, expand Default Web Site, and click Director.
  3. In the middle pane, double-click Application Settings.
  4. Find the entry for Service.AutoDiscoveryAddresses, and double-click it.
  5. If Director is installed on a Controller, localhost should already be entered.
  6. Add a comma, and the NetBIOS name of one of the controllers in the 2nd XenDesktop Site (farm). Only enter one Controller name. If you have multiple Director servers, you can point each Director server to a different Controller in the 2nd XenDesktop Site (farm). From Citrix Docs: Director automatically discovers all other Controllers in the same Site and falls back to those other Controllers if the Controller you specified fails.

Director Process Monitoring

Director 7.11 and newer have Process Monitoring, which is detailed in Citrix Blog Post Citrix Director: CPU, Memory Usage and Process Information.

Process Monitoring is disabled by default. To enable it, configure the Enable process monitoring setting in a Citrix Policy. For Citrix Policies in a GPO, find this setting in the computer half of the GPO. Note: this setting could significantly increase the size of the Monitoring database.

Director Alerts and Notifications

Director supports alert conditions and email notifications. This feature requires XenApp/XenDesktop to be licensed with Platinum Edition. See Citrix Blog Post Configuring & Managing Alerts and Notifications Using Director for more information.

Director 7.11 and newer have CPU, Memory, and ICT RTT alerts. Citrix Blog Post 7 New Categories in Director for Proactive Notifications & Alerts

  7. Notice the Conditions that are already enabled. You can change them or add more.
  8. On the bottom right, in the Notification preferences section, click Add.
  9. Enter an email address, and click Done.
  10. On the bottom, click Save.
  11. You can create custom Alert Policies by clicking the Create button on any of these tabs.
  12. For Server OS and User Policy, there are new ICA RTT alerts. See Citrix Blog Post 7 New Categories in Director for Proactive Notifications & Alerts for details on the new alerts in 7.11 and newer.
  13. In Director 7.12 and newer, you can configure alerts to generate an SNMP trap. This is configured in PowerShell as described at Configure alerts policies with SNMP traps at Citrix Docs.
    Set-MonitorNotificationSnmpServerConfiguration        #see Docs for parameter details
    Set-MonitorNotificationPolicy -IsSnmpEnabled $true -Uid <Policy ID>
  14. Citrix has an experimental Desktop Notification Tool. See Citrix Blog Post Desktop Notification Tool For Citrix XenDesktop.

Director – SCOM Integration

Director 7.8 and newer can display alerts from System Center Operations Manager 2012 R2. This feature requires XenApp/XenDesktop Platinum Edition.

  1. See Configure SCOM integration at Citrix Docs for detailed configuration instructions. Also see Marius Sandbu Integrating Citrix XenDesktop 7.7 and System Center Operations Manager.
  2. If Director server or System Center Operations Manager server is 2008 R2, then login to the 2008 R2 server, open PowerShell and run Enable-PSRemoting. Yes to everything. This is not needed on Windows Server 2012 R2 servers.
  3. On Director server, run C:\inetpub\wwwroot\Director\tools\DirectorConfig.exe /configscom
  4. FYI, the DirectorConfig.exe /configscom command enables the following features on the Director server: /FeatureName:IIS-NetFxExtensibility45 /FeatureName:IIS-ASPNET45 /FeatureName:WCF-HTTP-Activation45
  5. FYI, the System Center Operations Manager server is listed in IIS Manager at Default Web Site > Director > Application Settings (middle pane) > Connector.SCOM.ManagementServer.
  6. On the System Center Operations Manager server, edit Remote Management Users local group, and add Citrix Admins, and other Director users.
  7. In System Center Operations Manager Console, go to Administration > User Roles, and edit Operations Manager Operators. Add the Citrix Admins, and other Director users.
  8. See Citrix Blog Post SCOM Alerts in Citrix Director for information on how to view System Center Operations Manager alerts in Director.

Director – Custom Reports

In Director 7.12 and newer, in the Trends view, there’s a Custom Reports tab that guides you through creating a custom OData Query. This tab only appears if you have XenApp/XenDesktop Platinum Edition.

The Monitoring database contains more data than is exposed in Director. To view this data, the Monitoring service has an OData Data Feed that can be queried.

Use Director

The newer Director features usually require Delivery Controllers and VDAs to be at the same version or newer than Director. Director depends on the Monitoring Service that is built into the Delivery Controller. The Monitoring Service gathers data from the VDAs.

See Monitor deployments at Citrix Docs.

See the various Troubleshoot topics at Citrix Docs.

New features in Director 7.18 and newer:

  • In Director, you can view the details of a VDA machine (instead of a user session). If the machine is unregistered, then there’s a link to Health Assistant, which opens Troubleshoot machines  at Citrix Docs.

New features in Director 7.16 and newer:

In Director 7.14 and newer, see CTX223927 How to use Director to troubleshoot application launch errors. This feature is configured in Citrix Policy Settings located in the Computer half at Virtual Delivery Agent Settings > Monitoring. Also see Citrix Blog Post Application Related Session Failure Reporting in Citrix Director 7.15.

In Director 7.14 and newer, see CTX223928 How to use Director to monitor storage performance.

Citrix Blog Post Citrix Director Now Provides Disk Usage Information!:

  • IOPS and disk latency data is enabled by default.
  • IOPS and disk latency is pushed to the database from each VDA at 1 hour interval.
  • Approximately 276 KB of disk space is required to store the CPU, memory, IOPS and disk latency data for one VDA over a period of one year.

In Director 7.14 and newer, see CTX223925 How to use Director to monitor NVIDIA GPU usage.

Citrix Director 7.13 and newer have an Application Instances tab on the Filters page that lets you filter published application sessions based on Session Idle Time (RDS sessions only), Application Name, and all other existing fields, like machine name, and so on. Requires Director 7.13, Controller 7.13, VDA 7.13, and Platinum Edition licensing. See Citrix Blog Post Monitoring Idle Applications and Sessions in Citrix Director. See Troubleshoot applications at Citrix Docs.

If idle time column shows n/a, then you need to wait 10-15 minutes.

In Director 7.13 and newer, the Session Details panel can show if Enlightened Data Transport (EDT, aka HDX on UDP) is enabled in the user’s session. See Citrix Blog Post HDX Adaptive Transport Protocol Monitoring via Director.

George Spiers has a comprehensive guide of all Director 7.12 features at http://www.jgspiers.com/citrix-director/.

Hypervisor Host Hardware

  • Citrix Blog Post Citrix Scalability — The Rule of 5 and 10: Simply take the number of physical cores in a hypervisor host, multiply it by 5 or 10, and the result will be your Single Server Scalability. Use 5 if you’re looking for the number of XenDesktop VMs you can host on a box, and use 10 if you’re looking for the number of XenApp user sessions you can host on a box.

Virtual Machine Hardware

  1. Operating system version support: VDA 7.18 supports Windows 10 (1607 and newer), Windows Server 2012 R2 (RDSH only), and Windows Server 2016 (RDSH or Server VDI).
    1. For older operating systems (e.g Windows 7 or Windows Server 2008 R2), install VDA 7.15 with the latest Cumulative Update. VDA 7.15 will work with newer Delivery Controllers (e.g. Delivery Controller 7.18).
  2. Microsoft TechNet Blog – Say No to Windows 10 Long Term Servicing Channel (LTSC)  💡
    • No Edge
    • From January 2020, Microsoft Office 365 will not be supported on LTSC
    • Non-security operating system fixes and enhancements may not get back-ported to LTSC
  3. CTX224843 Windows 10 compatibility with Citrix XenDesktop
  4. Firewall – VDA 7.18 enables the UDP-based EDT protocol by default. Make sure the UDP ports are open for ICA/HDX:
    1. UDP 1494
    2. UDP 2598
    3. UDP 443 – from Internet to NetScaler Gateway.
    4. UDP 443 can also be used by internal ICA connections if VDA SSL is configured.
    5. For EDT through NetScaler Gateway, make sure your NetScaler firmware is up to date, preferably 11.1 build 56 or newer.
  5. VDA virtual machine sizing:
    1. For Windows 10 virtual desktops, give the virtual machine: 2+ vCPU and 2+ GB of RAM
    2. For Windows 2012 R2 RDSH, give the virtual machine 8 vCPU, and 24-48 GB of RAM
    3. See Daniel Feller Sizing Windows 2016, Windows 2012 And Windows 10 Virtual Machines
  6. If using RAM caching (MCSIO or PvS), add more RAM for the cache
  7. Remove the floppy drive
  8. Remove any serial or LPT ports
  9. If vSphere:
    1. To reduce disk space, reserve memory. Memory reservations reduce or eliminate the virtual machine .vswp file.
    2. The NIC should be VMXNET3.
  10. If this VDA will boot from Provisioning Services:
    1. For vSphere, the NIC must be VMXNET3.
    2. For vSphere, configure the CD-ROM to boot from IDE instead of SATA. SATA comes with VM hardware version 10. SATA won’t work with PvS.
  11. Install the latest version of hypervisor drivers (e.g. VMware Tools).
  12. The vSphere Activity Monitoring Feature with NSX Guest Introspection feature uses a TDI driver (vnetflt.sys), which might cause a “Connection Interrupted” message when users log off of Citrix. See CTX221206 “Connection Interrupted” error message displayed while logging off ICA session.

If vSphere, disable NIC Hotplug

  1. Users could use the systray icon to Eject the Ethernet Controller. Obviously this is bad.
  2. To disable this functionality, power off the virtual machine.
  3. Once powered off, right-click the virtual machine, and click Edit Settings.
  4. On the VM Options tab, expand Advanced, and then click Edit Configuration.
  5. On the bottom left, enter devices.hotplug. On the right, enter false. Then click Add.
  6. Then click OK a couple times to close the windows.
  7. The VM can then be powered on.

Windows Preparation

  1. Computer Group Policy – Make sure the Master VM is in the same OU as the Linked Clones so the Master VM will get the computer-level GPO settings in its registry. Run gpupdate on the master after moving the VM to the correct OU. When Clones are created from the Master, the computer-level GPO settings will already be applied, thus eliminating a timing issue.
  2. If Server OS, disable IE Enhanced Security Configuration in Server Manager > Local Server.
  3. Optionally, go to Action Center (Windows 2012 R2) or Control Panel > Security and Maintenance (Windows 10/2016) to disable User Account Control, and enable SmartScreen.

    1. In Windows 10 1703 and newer, search the Settings app for Change User Account Control settings.
    2. SmartScreen is configured in Windows Defender Security Center > App & browser control.
  4. Run Windows Update. Do not skip this step. Many VDA installation problems are fixed by simply updating Windows.


    1. Defer Feature Updates – For Windows 10, since Citrix VDA does not immediately support new Windows 10 versions, configure Windows Update to defer feature updates.


  5. Add your Citrix Administrators group to the local Administrators group on the VDA. Computer Management.
  6. The Remote Desktop Services “Prompt for Password” policy prevents Single Sign-on to the Virtual Delivery Agent. Check registry key HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services. If fPromptForPassword = 1 then you need to fix group policy. The following GPO setting will prevent Single Sign-on from working.
    Computer Configuration | Policies | Administrative Templates | Windows Components | Remote Desktop Services | Remote Desktop Session Host | Security | Always prompt for password upon connection
    Or set the registry value HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\PorticaAutoLogon (DWORD) = 0x10.
  7. To remove the built-in apps in Windows 10, see Robin Hobo How to remove built-in apps in Windows 10 Enterprise.
  8. For Remote Assistance in Citrix Director, configure the GPO setting Computer Configuration | Policies | Administrative Templates | System | Remote Assistance | Offer Remote Assistance. See Jason Samuel – How to setup Citrix Director Shadowing with Remote Assistance using Group Policy for more details.
  9. If you intend to use Citrix’s SCOM Management Packs for XenApp/XenDesktop, make sure WinRM is enabled on the VDA by running winrm quickconfig. Or you can enable WinRM using Group Policy.

Install Virtual Delivery Agent 7.18

  1. For virtual desktops, make sure you are logged into the console. The VDA won’t install if you are connected using RDP.
  2. Make sure .NET Framework 4.5.2 or newer is installed.

CLI Install:

Command Line Install Options are detailed at Install using the command line at Citrix Docs.

The Citrix Telemetry Service seems to cause problems. You can use the Command Line Installer to exclude Telemetry Service as detailed at VDA upgrade cmdlet at Citrix Discussions.

Citrix Desktop Helper Service

Citrix Blog Post Augment Your XenDesktop Deployment with the Desktop Helper Service: this installable service adds the following functionality to your VDAs:

  • The “Shutdown Inactive Desktops” feature allows Citrix administrators to enable a timer that shuts down a virtual desktop after it has been registered for a configured amount of minutes without a user connection.
  • Delaying the Citrix Desktop Service start by a configurable amount of time allows the desktop to finish performing on-boot tasks before a user is brokered to it.
  • The “Force Group Policy Update” feature give administrators the ability to force a group policy update after a configured amount of time.

If these features are desirable, download the tool from the blog post and install it.

Configurable Registry keys are located at HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\DesktopHelper. Each value is detailed in the accompanying Word document.

Customer Experience Improvement Program (CEIP)

Customer Experience Improvement Program (CEIP) is enabled by default. To disable it, create the registry value HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Telemetry\CEIP\Enabled (DWORD), and set it to 0 (zero). Also see CEIP at Citrix Insight Services at Citrix Docs.

See http://www.carlstalhood.com/delivery-controller-7-18-and-licensing/#ceip for additional places where CEIP is enabled.

Connection Quality Indicator

The Connection Quality Indicator tells the user the quality of the connection. For example:

Position of the indicator is configurable by the user. Thresholds are configurable through group policy.

Download it from CTX220774 Connection Quality Indicator and install it. The article is very detailed.

Group Policy templates are located at C:\Program Files (x86)\Citrix\Connection Quality Indicator\Configuration. Copy the files and folder to <Sysvol>\Policies\PolicyDefinitions, or C:\Windows\PolicyDefinitions.

Find the settings under Computer Config | Policies | Administrative Templates | Citrix Components | Virtual Desktop Agent | CQI

Version 1.2 adds the GPO settings to the user half of a GPO.

Notification display settings lets you customize the user notifications, or disable them.

Connection Threshold Settings lets you set the notification thresholds.

Adaptive Transport

XenApp/XenDesktop 7.18 includes Adaptive Transport, which uses EDT protocol, which uses UDP Ports 1494/2598 for HDX connections to the VDA. The UDP ports should already be open in the Windows Firewall.

For EDT through NetScaler Gateway, make sure your NetScaler firmware is up to date, preferably 11.1 build 56 or newer.

In 7.18, Adaptive Transport defaults to Preferred, which means it’s enabled by default. It can be configured in the Citrix Policy setting HDX Adaptive Transport.

Slow Logons

If logging in to a VDA from Citrix ICA, RDP, and Console results in a permanent black screen, then you might have to disable the App Readiness service. Source = CTX216590 Logon Delay and Black screen on logon for up to 10 seconds after upgrading from XA 7.5 to XA 7.6.

 

Citrix Discussions Xenapp 7.9: Wait for local session manager: “I have a Xenapp 7.9 environment on Windows 2012 R2. When logging in through Citrix I got message “Wait for local session manager” for 20-30 seconds. When logging in to the server with RDS, I do not have to wait for this.”

“Add the following 2 registry keys to your 7.9 VDA server – then try connecting to it using ICA to see if the issue still occurs:

Add reg keys in “HKLM\SOFTWARE\Citrix\GroupPolicy”
Dword: “CacheGpoExpireInHours” – Value = 5-24 (# of Hours) ***start with value of 5***
Dword: “GpoCacheEnabled” – Value = 1

Restart the machine after adding these registry keys and attempt an ICA connection (at least twice) to see if that helps the Login delay.”

 

Mark DePalma at XenApp slow logon times, user get black screen for 20 seconds at Citrix Discussions says that pushing Tile Refresh to a background task speeds up logons.

  1. Regedit:
    Windows Registry Editor Version 5.00

    Registry - 'SOFTWARE\Microsoft\Active Setup\Installed Components\DisableUPMResetCache'

 

Marvin Neys at XenApp slow logon times, user get black screen for 20 seconds at Citrix Discussions says that deleting HKCU\Software\Microsoft\Windows\CurrentVersion\UFH\SHC at logoff reduces logon times from 40 seconds to 6 seconds.

Remove-Item HKCU:\Software\Microsoft\Windows\CurrentVersion\UFH\SHC

 

For additional logon delay troubleshooting, see Alexander Ollischer XenApp/XenDesktop – “Please Wait For Local Session Manager” message when logging into RDS. He found some Windows Updates that caused a logon delay.

 

XenApp recalculates WMI filters on every reconnect. CTX212610 Session Reconnect 30 sec Delay – DisableGPCalculation – WMI Filters indicates that recalculation can be disabled by setting HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Reconnect\DisableGPCalculation (DWORD) to 1.

  7. If you see a Smart Tools page, make a selection for Call Home, and click Next.
  8. In the Finish Reconfiguration page, click Finish.
  9. Restart the VDA machine.
  10. You must also change the VDA registration port on the Delivery Controllers by running BrokerService.exe /VDAPort.
  11. For Local Host Cache, on the Delivery Controller, run C:\Program Files\Citrix\Broker\Service\HighAvailabilityService.exe –VdaPort <CORRECT PORT #>. Source = CTX229493 VDAs Do Not Register in LHC Mode When Registration Port is Not Set To Default.

Verify that VDA registered with a Controller

  1. If you restart the Virtual Delivery Agent machine, or restart the Citrix Desktop Service
  2. In Windows Logs > Application log, you should see an event 1012 from Citrix Desktop Service saying that it successfully registered with a controller.
  3. If you don’t see successful registration, then you’ll need to fix the ListOfDDCs registry key.
    1. See VDA registration with Controllers at Citrix Docs.
    2. See The Most Common VDA Registration Issues & Troubleshooting Steps at Citrix Blogs.
  4. You can also run Citrix’s Health Assistant on the VDA.
  5. See CTX220772 Technical Primer: VDA Registration for a very detailed explanation of the VDA Registration process.

Citrix PDF Printer  for Receiver for HTML5/Chrome

  1. VDA 7.18 installs the PDF Printer automatically so there’s no need for a separate installation.
  2. To enable the PDF printer for HTML5 connections, configure the Citrix Policy setting called Auto-create PDF Universal Printer in the user half of a Citrix Policy GPO.

Citrix File Access 2.0.3 for Receiver for Chrome

  1. If you support Receiver for Chrome (Chromebook) and want published applicatons to open files on Google Drive, install Citrix File Access on the VDAs. Get it from the Receiver for Chrome download page, in the Additional Components section.
  2. Go to the extracted Citrix_File_Access_2.0.3, and run FileAccess.msi.
  3. In the Please read the File Access License Agreement page, check the box next to I accept the terms, and click Install.
  4. In the Completed the File Access Setup Wizard page, click Finish.
  5. File Access is listed in Programs and Features (or Apps & Features) as version 2.0.3.33.

  6. File Access has a default list of supported file extensions. The list can be expanded by editing the registry on the VDA. See CTX219983 Receiver for Chrome Error: Invalid command line arguments: Unable to open the file as it has an unsupported extension.
  7. To open a file from Google Drive, right-click and and open the file using Citrix Receiver.

Framehawk Configuration

To enable Framehawk, see http://www.carlstalhood.com/citrix-policy-settings/#framehawkconfig

Remote Desktop Licensing Configuration

On 2012 R2 and newer RDSH, the only way to configure Remote Desktop Licensing is using group policy (local or domain). This procedure is not needed on virtual desktops.

  1. For local group policy, run gpedit.msc. Alternatively, you can configure this in a domain GPO.
  2. Go to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Licensing.
  3. Double-click Use the specified Remote Desktop license servers. Change it to Enabled, and enter the names of the RDS Licensing Servers (typically installed on XenDesktop Delivery Controllers). Click OK.
  4. Double-click Set the Remote Desktop licensing mode. Change it to Enabled and select Per User. Click OK.
  5. Optionally, you can install the Remote Desktop Licensing Diagnoser Tool. In the Server Manager > Add Roles and Features Wizard, on the Features page, expand Remote Server Administration Tools, expand Role Administration Tools, expand Remote Desktop Services Tools, and select Remote Desktop Licensing Diagnoser Tool. Then Finish the wizard.
  6. If it won’t install from Server Manager, you can install it from PowerShell by running Install-WindowsFeature rsat-rds-licensing-diagnosis-ui.
  7. In Server Manager, open the Tools menu, expand Remote Desktop Services (or Terminal Services), and click Remote Desktop Licensing Diagnoser.

  8. The Diagnoser should find the license server, and indicate the licensing mode. If you’re configured for Per User licenses, then it’s OK if there are no licenses installed on the Remote Desktop License Server.

Several people in Citrix Discussions reported the following issue: If you see a message about RD Licensing Grace Period has expired even though RD Licensing is properly configured, see Eric Verdumen No remote Desktop Licence Server availible on RD Session Host server 2012. The solution was to delete the REG_BINARY in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM\GracePeriod only leaving the default. You must take ownership and give admin users full control to be able to delete this value.

C: Drive Permissions

This section is more important for shared VDAs like RDSH (Windows Server 2012 R2, and Windows Server 2016).

The default permissions allow users to store files on the C: drive in places other than their profile.

  1. Open the Properties dialog box for C:.
  2. On the Security tab, click Advanced.
  3. If UAC is enabled, click Change permissions.
  4. Highlight the line containing Users and Create Folders, and click Remove.
  5. Highlight the line containing Users and Create files (or Special), and click Remove. Click OK.
  6. Click Yes to confirm the permissions change.
  7. If you see any of these Error Applying Security windows, click Continue. This window should appear multiple times.
  8. Click OK to close the C: drive properties.

Pagefile

If this image will be converted to a Provisioning Services vDisk, then you must ensure the pagefile is smaller than the cache disk. For example, if you allocate 20 GB of RAM to your Remote Desktop Session Host, and if the cache disk is only 15 GB, then Windows will have a default pagefile size of 20 GB, and Provisioning Services will be unable to move it to the cache disk. This causes Provisioning Services to cache to server instead of caching to your local cache disk (or RAM).

  1. Open System. In 2012 R2 and newer, you can right-click the Start button, and click System. Note: in Windows 10 1703 and newer, this method no longer opens the correct tool.
  2. Another option is to open File Explorer, right-click This PC, and click Properties. This works in Windows 10 1703.
  3. Click Advanced system settings.
  4. On the Advanced tab, click the top Settings button.
  5. On the Advanced tab, click Change.
  6. Uncheck the box next to Automatically manage paging file size for all drives. Then either turn off the pagefile, or set the pagefile to be smaller than the cache disk. Don’t leave it set to System managed size. Click OK several times.

Direct Access Users

When Citrix Virtual Delivery Agent is installed on a machine, non-administrators can no longer RDP to the machine. A new local group called Direct Access Users is created on each Virtual Delivery Agent. Add your non-administrator RDP users to this local group so they can RDP directly to the machine.

From CTX228128 What is the HKLM\Software\Citrix\PortICA\DirectAccessUsers registry function: The HKLM\Software\Citrix\PortICA\DirectAccessUsers registry key determines which Local group the VDA references to determine if a user should be allowed Unbrokered RDP access. Members of the Local Administrators group will always be granted access. If the Registry Key does not exist, or gets deleted, VDA will always allow the Unbrokered RDP Connection. The Registry key and local group are created as part of the VDA installation process.

Windows Profiles v3/v4/v5/v6

Roaming Profiles are compatible only between the following client and server operating system pairs. The profile version is also listed.

  • v6 = Windows 10 (1607 and 1703) and Windows Server 2016
  • v5 = Windows 10 (1511 and older)
  • v4 = Windows 8.1 and Windows Server 2012 R2
  • v3 = Windows 8 and Windows Server 2012
  • v2 = Windows 7 and Windows Server 2008 R2
  • v2 = Windows Vista and Windows Server 2008

For Windows 2012 R2, install Microsoft hotfix 2890783, and set the UseProfilePathExtensionVersion registry value to 1.

CTX230343 Reset Profile Options Is Greyed Out In Citrix Director states that the UseProfilePathExtensionVersion registry value is required on Windows 2012 R2 to enable Director users to reset profiles.

Black Screen when launch Published Apps on Windows Server 2016

From CTX225819 When Launching an Application Published from Windows Server 2016, a Black Screen Appears for Several Seconds Before Application is Visible: Citrix and Microsoft have worked together together to deliver code fixes for both Windows Server 2016 and XenApp. Microsoft is targeting their KB4034661 patch for the third week of August 2017. This fix requires a registry edit to enable.

  • Key = HKLM\SOFTWARE\Citrix\Citrix Virtual Desktop Agent
    • Value = DisableLogonUISuppression (DWORD) = 0

Published Explorer

From Citrix CTX128009 Explorer.exe Fails to Launch: When publishing the seamless explorer.exe application, the session initially begins to connect as expected. After the loading, the dialog box disappears, and the Explorer application fails to appear. On the VDA, use the following registry change to set the length of time a client session waits before disconnecting the session:

  • Key = HKLM\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI
    • Value = LogoffCheckerStartupDelayInSeconds (DWORD) = 10 (Hexadecimal)

Screen Saver

From Citrix CTX205214 Screensaver Not Working in XenDesktop: By default, Screen Saver doesn’t work on Desktop OS. To enable it, on the VDA, configure the following registry value:

  • Key = HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Graphics
    • Value = SetDisplayRequiredMode (DWORD) = 0

Smart Cards

From CTX231942 Windows 10 April 2018 Update (v1803) – Citrix Known Issues – Smart Card Service (SCardSvr) will run only if a Smart Card reader is connected. As ICA sessions redirect the Smart Card, it finds the service not to be running and fails.

  • Key = HKEY_LOCAL_MACHINE\Software\WOW6432Node\Microsoft\Cryptography\Calais
    • Value = AllowServiceAccessWithNoReaders (DWORD) = 1

Logon Disclaimer Window Size

From XenApp 7.8 – Session Launch Security/Warning Login Banner at Citrix Discussions: If your logon disclaimer window has scroll bars, set the following registry values:

  • Key = HKEY_LOCAL_MACHINE\Software\Wow6432node\Citrix\CtxHook\AppInit_DLLS\Multiple Monitor Hook
    • Value = LogonUIWidth (DWORD) = 300
    • Value = LogonUIHeight (DWORD) = 200

Login Timeout

From Citrix CTX203760 VDI Session Launches Then Disappears: XenDesktop, by default, only allows 180 seconds to complete a logon operation. The timeout can be increased by setting the following:

  • Key = HKLM\SOFTWARE\Citrix\PortICA
    • Value = AutoLogonTimeout ( DWORD) = decimal 240 or higher (up to 3599).

Also see Citrix Discussions Machines in “Registered” State, but VM closes after “Welcome” screen.

    • Value =ApplicationLaunchWaitTimeoutMS (DWORD) = decimal 60000

HDX Flash

From Citrix Knowledgebase article CTX139939 – Microsoft Internet Explorer 11 – Citrix Known Issues: The registry key value IEBrowserMaximumMajorVersion is queried by the HDX Flash service to check for maximum Internet Explorer version that HDX Flash supports. For Flash Redirection to work with Internet Explorer 11 set the registry key value IEBrowserMaximumMajorVersion to 11 on the machine where HDX flash service is running. In case of XenDesktop it would be the machine where VDA is installed.

  • Key = HKLM\SOFTWARE\Wow6432Node\Citrix\HdxMediaStreamForFlash\Server\PseudoServer
    • Value = IEBrowserMaximumMajorVersion (DWORD) = 11 (Decimal)

From Citrix Discussions: Add the DWORD FlashPlayerVersionComparisonMask=0 on the VDA under HKLM\Software\Wow6432Node\Citrix\HdxMediaStreamForFlash\Server\PseudoServer.  This disables the Flash major version checking between the VDA and Client Device.

Receiver for HTML5/Chrome Enhanced Clipboard

From About Citrix Receiver for Chrome 1.9 at Citrix Docs: To enable enhanced clipboard support, create a REG_SZ registry value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\Virtual Clipboard\Additional Formats\HTML Format\Name=”HTML Format”. Create any missing registry keys. This applies to both virtual desktops and Remote Desktop Session Hosts.

Receiver for HTML5/Chrome Upload Folder

The Receiver for HTML5 (or Chrome) lets upload files.

By default, the user is prompted to select a upload location. If you use the Upload feature multiple times, the last selected folder is not remembered.

Citrix CTX217351 How to Customize File Upload and Download Using Receiver for HTML5 and Receiver for Chrome. You can specify a default uploads location by editing HKLM\Software\Citrix\FileTransfer\UploadFolderLocation on the VDA. Environment variables are supported. When this value is configured, users are no longer prompted to select an upload location. The change takes effect at next logon.

Note: HTML5/Chrome Receiver also adds a Save to My Device location to facilitate downloads.

4K Monitors

From Citrix Knowledgebase article CTX218217 Unable to span across multiple monitors after upgrade to 7.11 VDA, Black/Blank screen appears on the monitors while connecting to ICA session:

  1. For VDA 7.11 and newer, calculate the video memory that is required for monitors using the following formula:
    SumOfAllMons (Width * Height) * 4 / 0.3, where width and height are resolution of the monitor. Note: There is no hard and fast rule that will work for all cases.
    Example: Consider the resolution of monitor 1 is 1920*1200 and monitor 2 is 1366*768. Then SumOfAllMons will be (1920*1200 + 1366*768)
  2. CTX115637 Citrix Session Graphics Memory Reference describes how multi-monitor resolution is determined.
  3. Open the registry (regedit) and navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\vbdenum
  4. Increase the value of “MaxVideoMemoryBytes” REG_DWORD value to the above calculated memory.
  5. Reboot the VDA.

Citrix Policies also control graphics performance.

COM Port Threads

CTX212090 COM Port Intermittently Inaccessible During ICA Sessions: increase the default value of “MaxThreads” under the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\picaser\Parameters from 20 to a value greater than the number of COM port connections you want to support. For example, if a XenApp server supports 100 sessions and each session opens two COM ports, the value of “MaxThreads” should be greater than 200.

NVIDIA GRID License

Allow NVIDIA GRID License to apply after the session is started. (Source = Jan Hendrik Meier NVIDIA GRID license not applied before the user connects – License Restriction will not be removed until the user reconnects)

  • Key = HKLM\SOFTWARE\NVIDIA Corporation\Global\GridLicensing
    • Value = IgnoreSP (DWORD) = 1

Legacy Client Drive Mapping

Citrix CTX127968 How to Enable Legacy Client Drive Mapping Format on XenApp: Citrix Client Drive Mapping no longer uses drive letters and instead they appear as local disks. This is similar to RDP drive mapping.

The old drive letter method can be enabled by setting the registry value:

  • Key = HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\UncLinks (create the key)
    • Value = UNCEnabled (DWORD) = 0

When you reconnect, the client drives will be mapped as drive letters (starts with V: and goes backwards).

Print Driver for Non-Windows Clients

From CTX139020 Configuring Virtual Machines for Mac Client Printer Mapping with Windows 8.x. By default, Non-Windows clients cannot map printers due to a missing print driver on the VDA machine.

  1. Requirements:
    • Internet Access
    • Windows Update service enabled
  2. Click Start, and run Devices and Printers.

    1. In Windows 10 1703, open Printers & scanners, then scroll down, and click Devices and printers.

  3. In the Printers section, highlight a local printer (e.g. Microsoft XPS Document Writer). Then in the toolbar, click Print server properties.

  4. Switch to the Drivers tab. Click Change Driver Settings.
  5. Then click Add.
  6. In the Welcome to the Add Printer Driver Wizard page, click Next.
  7. In the Processor Selection page, click Next.
  8. In the Printer Driver Selection page, click Windows Update. The driver we need won’t be in the list until you click this button. Internet access is required.
  9. Once Windows Update is complete, highlight HP on the left, and then select HP Color LaserJet 2800 Series PS (Microsoft) on the right. Click Next.
  10. In the Completing the Add Printer Driver Wizard page, click Finish.
  11. Repeat these instructions to install the following additional drivers:
    • HP LaserJet Series II
    • HP Color LaserJet 4500 PCL 5

SSL for VDA

If you intend to use HTML5 Receiver internally, install certificates on the VDAs so the WebSockets (and ICA) connection will be encrypted. Internal HTML5 Receivers will not accept clear text WebSockets. External users don’t have this problem since they are SSL-proxied through NetScaler Gateway.

Notes:

  • Each Virtual Delivery Agent needs a machine certificate that matches the machine name. This is feasible for a small number of persistent VDAs. For non-persistent VDAs, you’ll need some automatic means for creating machine certificates every time they reboot.
  • As detailed in the following procedure, use PowerShell on the Controller to enable SSL for the Delivery Group. This forces SSL for every VDA in the Delivery Group, which means every VDA in the Delivery Group must have SSL certificates installed.

The following instructions for manually enabling SSL on VDA can be found at Configure TLS on a VDA using the PowerShell script at Citrix Docs.

  1. On the VDA machine, run certlm.msc.
  2. Right-click Personal, expand All Tasks, and click Request New Certificate to request a certificate from your internal Certificate Authority. You can use either the Computer template or the Web Server template.

    • You can also use group policy to enable Certificate Auto-Enrollment for the VDA computers.
  3. Browse to the XenApp/XenDesktop 7.18 ISO. In the Support\Tools\SslSupport folder, shift+right-click the Enable-VdaSSL.ps1 script, and click Copy as path.
  4. Run PowerShell as administrator (elevated).
  5. Run the command Set-ExecutionPolicy unrestricted. Enter Y to approve.
  6. In the PowerShell prompt, type in an ampersand (&), and a space.
  7. Right-click the PowerShell prompt to paste in the path copied earlier.
  8. At the end of the path, type in -Enable
  9. If there’s only one certificate on this machine, press Enter.
  10. If there are multiple certificates, then you’ll need to specify the thumbprint of the certificate you want to use. Open the Certificates snap-in, open the properties of the machine certificate you want to use, and copy the Thumbprint from the Details tab.

    In the PowerShell prompt, at the end of the command, enter ‑CertificateThumbPrint, add a space, and type quotes (").
    Right-click the PowerShell prompt to paste the thumbprint.
    Type quotes (") at the end of the thumbprint. Then remove all spaces from the thumbprint. The thumbprint needs to be wrapped in quotes.
  11. There are additional switches to specify minimum SSL Version and Cipher Suites. Also see Citrix CTX226049 Disabling Triple DES on the VDA breaks the VDA SSL connection.
  12. Press <Enter> to run the Enable-VdaSSL.ps1 script.
  13. Press <Y> twice to configure the ACLs and Firewall.
  14. You might have to reboot before the settings take effect.
  15. Login to a Controller, and run PowerShell as Administrator (elevated).
  16. Run the command asnp Citrix.*
  17. Enter the command:
    Get-BrokerAccessPolicyRule -DesktopGroupName '<delivery-group-name>' | Set-BrokerAccessPolicyRule ‑HdxSslEnabled $true

    where <delivery-group-name> is the name of the Delivery Group containing the VDAs.

  18. You can run Get-BrokerAccessPolicyRule -DesktopGroupName '<delivery-group-name>' to verify that HDX SSL is enabled.
  19. Also run the following command to enable DNS resolution.
    Set-BrokerSite –DnsResolutionEnabled $true

  20. Since VDA 7.18 defaults to enabling the UDP-based EDT protocol, open port UDP 443 to the VDAs.

You should now be able to connect to the VDA using the HTML5 Receiver from internal machines.

The Citrix blog post How To Secure ICA Connections in XenApp and XenDesktop 7.6 using SSL has a method for automatically provisioning certificates for pooled virtual desktops by enabling certificate auto-enrollment and setting up a task that runs after the certificate has been enrolled.

  • From Russ Hargrove at A note on VDA certificates in 7.14 at Citrix Discussions: Citrix installs a new “Citrix XenApp/XenDesktop HDX Service” certificate in the Personal store which breaks the automation of the Enable-VdaSSL.ps1 script. To fix the problem, modify the task scheduler powershell script to:
    Enable-VdaSSL.ps1 -Enable -CertificateThumbPrint (Get-ChildItem -path cert:\LocalMachine\My | Where-Object -FilterScript {$_.Subject -eq ""} | Select-Object -ExpandProperty Thumbprint) -Confirm:$False
  • For certificate auto-enrollment on non-persistent Remote Desktop Session Hosts (aka Server OS VDAs), see Non-Persistent Server SSL to VDA by Alfredo Magallon Arbizu at CUGC.

Anonymous Accounts

If you intend to publish apps anonymously then follow this section.

  1. Anonymous accounts are created locally on the VDAs. When XenDesktop creates Anon accounts, it gives them an idle time as specified at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\AnonymousUserIdleTime. The default is 10 minutes. Adjust as desired.
  2. Pre-create the Anon accounts on the VDA by running "C:\Program Files\Citrix\ICAConfigTool\CreateAnonymousUsersApp.exe". If you don’t run this tool, then anonymous users can’t login.
  3. You can see the local Anon accounts by opening Computer Management, expanding System Tools, expanding Local Users and Groups and clicking Users.
  4. If you want profiles for anonymous users to delete at logoff, then you’ll need to add the local Anon users to the local Guests group.
  5. If you open one of the accounts, on the Sessions tab, notice that idle timeout defaults to 10 minutes. Feel free to change it.

Group Policy for Anonymous Users

Since Anonymous users are local accounts on each Virtual Delivery Agent, domain-based GPOs will not apply. To work around this limitation, you’ll need to edit the local group policy on each Virtual Delivery Agent.

  1. On the Virtual Delivery Agent, run mmc.exe.
  2. Open the File menu, and click Add/Remove Snap-in.
  3. Highlight Group Policy Object Editor, and click Add to move it to the right.
  4. In the Welcome to the Group Policy Wizard page, click Browse.
  5. On the Users tab, select Non-Administrators.
  6. Click Finish.
  7. Now you can configure group policy to lockdown sessions for anonymous users. Since this is a local group policy, you’ll need to repeat the group policy configuration on every Virtual Delivery Agent image. Also, Group Policy Preferences is not available in local group policy.

Trend Micro

Trend Micro Slow login on Citrix environment after installing OfficeScan (OSCE): The following registries can be used to troubleshoot the issue. These registries will allow a delay on the startup procedure of OSCE until the system has launched successfully. This avoids deadlock situations during login.

Citrix CTX136680 – Slow Server Performance After Trend Micro Installation. Citrix session hosts experience slow response and performance more noticeable while users try to log in to the servers. At some point the performance of the servers is affected, resulting in issues with users logging on and requiring the server to be restarted. This issue is more noticeable on mid to large session host infrastructures.

Trend Micro has provided a registry fix for this type of issue. Create the following registry on all the affected servers. Add new DWORD Value as:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TmFilterParameters] “DisableCtProcCheck”=dword:00000001

Optimize Performance

VDA Optimizer

Installation of the VDA might have already done this, but there’s no harm in doing it again. This tool is only available if you installed VDA in Master Image mode.

  1. On the master VDA, go to C:\Program Files\Citrix\PvsVm\TargetOSOptimizer, and run TargetOSOptimizer.exe.
  2. Then click OK. Notice that it disables Windows Update.
  3. See CTX125874 How to Optimize XenDesktop Machines for the list of registry values changed by the TargetOSOptimizer tool. You can use Group Policy Preferences to set these values.

Windows 10 / Windows 2012 R2 / Windows 2016 and newer

Optimization Notes:

Seal and Shut Down

If this VDA will be a master image in a Machine Creation Services or Provisioning Services catalog, after the master is fully prepared (including applications), do the following:

  1. Go to the properties of the C: drive, and run Disk Cleanup.
  2. If Disk Cleanup is missing, you can run cleanmgr.exe instead.
  3. Windows 10 1703 and newer has a new method for cleaning up temporary files.
    1. Right-click the Start button, and click System.
    2. Click Storage on the left, and click This PC (C:) on the right.
    3. Click Temporary Files.
    4. Check boxes, and click Remove files.
  4. On the Tools tab, click Optimize to defrag the drive.
    `
  5. Run slmgr.vbs /dlv and make sure it is licensed with KMS and has at least one rearm remaining. It is not necessary to manually rearm licensing since MCS will do it automatically.
  6. Run Delprof2 to clean up local profiles. Get it from http://helgeklein.com/download/.
  7. Machine Creation Services and Provisioning Services require DHCP.
  8. Session hosts (RDSH) commonly have DHCP reservations.
  9. Login Base Image Script Framework (BIS-F) automates many sealing tasks. The script is configurable using Group Policy.
  10. Shut down the master image. You can now use Studio (Machine Creation Services) or Provisioning Services to create a catalog of linked clones.

Troubleshooting – Graphics

Citrix Blog post – Optimising the performance of HDX 3D Pro – Lessons from the field

From Citrix Knowledgebase article CTX218217 Unable to span across multiple monitors after upgrade to 7.11 VDA, Black/Blank screen appears on the monitors while connecting to ICA session:

  1. For VDA 7.11 and newer, calculate the video memory that is required for monitors using the following formula :
    SumOfAllMons (Width * Height) * 4 / 0.3, where width and height are resolution of the monitor. Note: There is no hard and fast rule that will work for all cases.
    Example: Consider the resolution of monitor 1 is 1920*1200 and monitor 2 is 1366*768. Then SumOfAllMons will be (1920*1200 + 1366*768)
  2. CTX115637 Citrix Session Graphics Memory Reference describes how multi-monitor resolution is determined.
  3. Open the registry (regedit) and navigate to:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\vbdenum
  4. Increase the value of “MaxVideoMemoryBytes” REG_DWORD value to the above calculated memory.
  5. Reboot the VDA

From Citrix Discussions: To exclude applications from Citrix 3D rendering, create a REG_DWORD registry value “app.exe” with value 0 or a registry value “*” with value 0.

  • Both x86 and x64:
    • reg add hklm\software\citrix\vd3d\compatibility /v * /t REG_DWORD /f /d 0

Wildcards are not supported. The asterisk * here has a special meaning “all apps” but is not a traditional wildcard. To blacklist multiple apps e.g. both appa.exe and appb.exe must be done by creating a registry value for each app individually.

This is most problematic in Remote PC since most physical PCs have GPUs. I recently had to blacklist Internet Explorer to prevent lockup issues when switching back to physical.

Uninstall VDA

Uninstall the VDA from Programs and Features.

Then see CTX209255 VDA Cleanup Utility.

To run the VDA Cleanup Tool silently:

  1. Execute VDACleanupUtility.exe /silent /noreboot to suppress reboot.
  2. Once the VDACleanupUtility has finished executing, setup Auto logon for the current user.
  3. Reboot.
  4. After reboot, tool will launch automatically to continue Cleanup.

Another option is to delete CitrixVdaCleanup value under HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce. Then after reboot, run VDACleanupUtility.exe /silent /reboot to indicate that it’s running after the reboot.

Change Log

Upgrade

If you are performing a new install of XenApp/XenDesktop Controller, then skip to the next section.

You can in-place upgrade directly from any Delivery Controller version 7.0 or newer. Citrix recommends upgrading Delivery Controller 5.6 to 7.6 LTSR Cumulative Update 5 before upgrading to 7.18.

During the upgrade of Delivery Controller, be aware that a database upgrade is required. Either get a DBA to grant you temporary sysadmin permission, or use Citrix Studio to generate SQL scripts that a DBA must then run in SQL Studio.

  1. SQL Server 2008 R2 – if your XenDesktop databases are on SQL 2008 R2, then you’ll need to upgrade SQL to 2012 or the 7.18 upgrade will fail. Known Issue.
  2. License Server Upgrade – Before upgrading to Delivery Controller 7.18, if you have a standalone Citrix Licensing Server, upgrade it to 11.15.0.0 build 24100. The Delivery Controllers will be non-functional until you upgrade the License Server.
  3. Frequent updates/upgrades– XenApp and XenDesktop 7.18 is a Current Release.
    • With Current Release (CR), you’re expected to upgrade to the future 7.19 (and 7.20, and 7.21, etc.) to receive bug fixes. Newer Current Releases come with new features, which might include new bugs. Current Releases are only supported for six months from the release date. That means you should plan to perform these upgrades at least twice a year.
    • If you don’t want to continuously upgrade to the latest Current Release, then you can stay on LTSR 7.15, which receives Cumulative Updates with bug fixes, but no new features. See Lifecycle Milestones for XenApp & XenDesktop.
  4. Delivery Controller OS Compatibility – XenDesktop 7.18 Delivery Controller is supported on Windows 2012 R2 and newer. Windows Server 2008 R2 is no longer supported.
  5. VDA OS Compatibility – Virtual Delivery Agent (VDA) 7.18 is only supported on a limited number of Windows operating system versions, specifically, Windows 10 (1607+), Windows Server 2012 R2, and Windows Server 2016.
    • If you have older VDA machines running Windows 7 or Windows Server 2008 R2, you can leave their VDA software at version 7.15 (with latest Cumulative Update). It is supported for VDA 7.15 to communicate with Delivery Controllers 7.18.
  6. SCOM Agent – If StoreFront is installed on the Controller, and if the Citrix SCOM Agent for StoreFront is installed, stop the Citrix MPSF Agent service. See CTX220935 Cannot Perform a StoreFront Upgrade if Citrix SCOM Management Pack Agent Service is Running.
  7. Close PowerShell and Consoles. Make sure all Citrix Consoles and PowerShell consoles are closed. StoreFront won’t upgrade if any are running. If StoreFront fails, then the StoreFront configuration is wiped out.
  8. Other Users – Use Task Manager > Users tab to logoff any other user currently logged into the machine.
  9. Snapshot. If StoreFront is installed on the Controller, take a snapshot before attempting the upgrade.
  10. Download the XenApp/XenDesktop 7.18 ISO.
  11. Before upgrading, open PowerShell and run the following.
    asnp citrix*
    Get-TrustDBConnection

    • If you don’t see a returned value, then you’ll need to run additional commands to fix the Trust Database Connection as detailed at Known Issues at Citrix Docs
      $cs = Get-ConfigDBConnection
      Set-TrustDBConnection –DBConnection $cs
  12. Run AutoSelect.exe from the 7.18 ISO.

  1. After Citrix Studio launches, if you have sysadmin permissions on SQL, then click Start the automatic Site upgrade. If you don’t have full permission, then get a DBA to help you, click Manually upgrade this site, and follow the instructions.

  2. If you choose to Manually upgrade this site, then note that there might not be an upgrade for the Logging Database schema, depending on what version you are upgrading from.

  3. After all Controllers and VDAs are upgraded, right-click the Catalogs, and click Upgrade Catalog. Note: 7.9 is the newest minimum functional level. You won’t see an option for 7.18. If your Catalogs are already set to VDA version 7.9, then there’s no need to upgrade the Catalogs or Delivery Groups.


  4. Then do the same for the Delivery Groups. Note: 7.9 is the newest minimum functional level. You won’t see an option for 7.18. If your Delivery Groups are already set to VDA version 7.9, then no upgrade is needed.


Other XenApp/XenDesktop components can also be in-place upgraded:

New Install Preparation

Frequent updates/upgrades

XenApp and XenDesktop 7.18 is a Current Release.

  • With Current Release (CR), you’re expected to upgrade to the future 7.18 (and 7.19, and 7.20, etc.) to receive bug fixes. Current Releases also come with new features, which might include new bugs. Current Releases are only supported for six months from the release date. That means you should plan to perform these upgrades at least twice a year.
  • If you don’t want to continuously upgrade to the latest Current Release, then you can stay on LTSR 7.15, which receives Cumulative Updates with bug fixes, but no new features. See Lifecycle Milestones for XenApp & XenDesktop.

VDA OS Compatibility

XenDesktop 7.18 Delivery Controller is supported on Windows 2012 R2 and newer. Windows Server 2008 R2 is no longer supported.

Virtual Delivery Agent (VDA) 7.18 is only supported on a limited number of Windows operating system versions, specifically, Windows 10 (1607+), Windows Server 2012 R2, and Windows Server 2016.

  • If you have older VDA machines running Windows 7 or Windows Server 2008 R2, you can install VDA software version 7.15. It is supported for VDA 7.15 to communicate with Delivery Controllers 7.18.

Installation Automation

If you want to automate the install of Delivery Controllers, see Dennis Span Citrix Delivery Controller unattended installation with PowerShell and SCCM.

Citrix Licensing

If you are going to use an existing Citrix Licensing Server, upgrade it to 11.15.0.0 build 24100.

Multiple License Types – Multiple license types (but not multiple editions) are supported in a single farm. See CTX223926 How to Configure Multiple License Types within a Single XenApp and XenDesktop Site.

SQL Databases for XenDesktop

  • Citrix CTX209080 Database Sizing Tool for XenDesktop 7
  • Citrix article CTX114501 – Supported Databases for XenApp and XenDesktop Components
  • Three databases – There are typically three databases: one for the Site (aka farm), one for Logging (audit log) and one for Monitoring (Director).
    • The name of the monitoring database must not have any spaces in it. See CTX200325 Database Naming Limitation when Citrix Director Accesses Monitoring Data Using OData APIs
    • If you want Citrix Studio to create the SQL databases automatically, then the person running Studio must be a sysadmin on the SQL instances. No lesser SQL role will work. sysadmin permissions can be granted temporarily and revoked after installation.
    • As an alternative, you can use Citrix Studio to create SQL scripts, and then run those scripts on the SQL server. In that case, the person running the scripts only needs the dbcreator and securityadmin roles.
    • It is possible to create the three databases in advance. However, you must use the non-default Latin1_General_100_CI_AS_KS collation.
  • SQL High Availability Options:
    • Basic Availability Groups – Build two SQL 2016 (or newer) Standard Edition servers, and create three Basic Availability Groups, one for each database. Each Basic Availability Group has its own Listener.
    • Database Mirroring – Build two SQL 2014 or older Standard Edition servers, and configure Database Mirroring.
    • AlwaysOn Availability Group – Build two SQL Enterprise Edition servers, and create one AlwaysOn Availability Group with one Listener.
    • Failover Clustering – Build two SQL Enterprise Edition servers, and configure SQL Database Failover Clustering.
  • Cloud – Azure SQL and AWS RDS are not supported. You’ll need to build your own SQL Servers on IaaS VMs.

Windows Feature

Installing Group Policy Management on the Delivery Controllers lets you edit Citrix-targeted Group Policy Objects (GPOs) directly from the Controllers. Controllers already have Studio and Citrix Group Policy Management installed, so if GPMC runs from a Controller, then the GPO Editor will automatically have access to the Citrix Policies node. Or you can install Citrix Group Policy Management Plug-in on a different machine that has GPMC installed.

vCenter Service Account

Create a role in vSphere Client. Assign a service account to the role at the Datacenter or higher level. Delivery Controller will use this service account to login to vCenter.

Delivery Controller Install

  1. A typical size for the Controller VMs is 2-4 vCPU and 8+ GB of RAM. If all components (Delivery Controller, StoreFront, Licensing, Director, SQL Express) are installed on one server, then you might want to bump up memory to 10 GB or 12 GB.
  2. From Local Host Cache sizing and scaling at Citrix Docs:
    1. For LHC LocalDB, assign the Controller VMs a single socket with multiple cores.
    2. Add two cores for LHC.
    3. Add at least three more Gigs of RAM and watch the memory consumption.
    4. Since there’s no control over LHC election, ensure all Controllers have the same specs.
  3. Make sure the User Right Log on as a service includes NT SERVICE\ALL SERVICES, or add NT SERVICE\CitrixTelemetryService to the User Right.
  4. Download the XenApp/XenDesktop 7.18 ISO.
  5. On two Delivery Controllers, to install the Delivery Controller software, run AutoSelect.exe from the 7.18 ISO.
  6. Click Start next to either XenApp or XenDesktop. The only difference is the product name displayed in the installation wizard.
  7. On the top left, click Delivery Controller.
  8. In the Licensing Agreement page, select I have read, understand, and accept the terms, and click Next.
  9. In the Core Components page, you can install all components on one server, or on separate servers. Splitting them out is only necessary in large environments, or if you have multiple farms, and want to share the Licensing, StoreFront, and Director components across those farms. Click Next.
  10. In the Features page, uncheck the box next to Install Microsoft SQL Server 2014 SP2 Express, and click Next.
  11. In the Firewall page, click Next.
  12. In the Summary page, click Install.
  13. The machine will probably reboot a couple times.

    1. After the reboot, and after logging in again, you might see a Locate ‘XenApp’ installation media window. Don’t click anything yet.
    2. Go to the XenApp_and_XenDesktop_7_18.iso file and mount it.
    3. Go back to the Locate ‘XenApp’ window.
    4. On the left, expand This PC, and click the DVD Drive.
    5. Click Select Folder.
    6. Installation will resume. Repeat these instructions after each reboot.
  14. In the Smart Tools page, make a selection. If you choose Smart Tools and Call Home, then click Connect, and enter your Citrix Cloud or MyCitrix.com credentials. Click Next.


  15. In the Finish page, click Finish. Studio will automatically launch.
  16. Ensure the two Controller VMs do not run on the same hypervisor host. Create an anti-affinity rule at vSphere Cluster > Manage > Settings > DRS Rules > Add. Set the Type to Separate Virtual Machines.

Create Site – Create Database

There are several methods of creating the databases for XenApp/XenDesktop:

  • If you have sysadmin permissions to SQL, let Citrix Studio create the databases automatically.
  • If you don’t have sysadmin permissions to SQL, then use Citrix Studio to generate SQL scripts, and send the scripts to a DBA.

Use Studio to Create Database Automatically

  1. Launch Citrix Studio. After it loads, click Deliver applications and desktops to your users.
  2. In the Introduction page, select An empty, unconfigured site. This reduces the number of pages in this Setup wizard. The other pages will be configured later.
  3. Enter a Site Name (aka farm name), and click Next. Only administrators see the farm name.
  4. In the Databases page, if you are building two Controllers, click Select near the bottom of the same page.

    1. Click Add.
    2. Enter the FQDN of the second Controller, and click OK. Note: the Delivery Controller software must already be installed on that second machine.
    3. Then click Save.
  5. If the person running Citrix Studio has sysadmin permissions to the SQL Server, then enter the SQL server name/instance in the three Location fields, and click Next.
  6. If you don’t have sysadmin permission, the jump to the SQL Scripts section below.
  7. On the Licensing page, enter the name of the Citrix License Server, and click Connect. If you installed Licensing with your Delivery Controller, then simply enter localhost.
  8. If the Certificate Authentication appears, select Connect me, and click Confirm.T
  9. Select your license type, and click Next. If you see both User/Device and Concurrent, then you usually must select User/Device licenses. Also see CTX223926 How to Configure Multiple License Types within a Single XenApp and XenDesktop Site.
  10. In the Summary page, if your databases are mirrored or in an Availability Group, each database will show high availability servers, and the name of the Mirror server. Click Finish.

  11. It will take some time for the site to be created.
  12. Once done, skip to the Second Controller section.

Use Studio to create SQL scripts

  1. If you don’t have SQL sysadmin permissions, then change the selection to Generate scripts to manually set up databases on the database server. Change the database names if desired, and click Next.
  2. In the Summary page, click Generate scripts.
  3. A folder will open with six scripts. Edit each of the scripts.
  4. Near the top of each script are two lines to create the database. Uncomment both lines (including the go line). Then save and close the file.

  5. Once all of the scripts are edited, you can send them to your DBA.
    1. On the Principal SQL Server, open the file Site_Principal.sql.

    2. Open the Query menu, and click SQLCMD Mode to enable it.
    3. Then execute the script.
    4. If SQLCMD mode was enabled properly, then the output should look something like this:
    5. If you have a mirrored database, run the second script on the mirror SQL instance. Make sure SQLCMD mode is enabled.
    6. Repeat for the Logging_Principal.sql script.
    7. You’ll have to enable SQLCMD Mode for each script you open.


    8. Repeat for the Monitoring_Principal.sql script.
    9. Once again enable SQLCMD Mode.


    10. The person running Citrix Studio must be added to the SQL Server as a SQL Login, and granted the public server role, so that account can enumerate the databases.

  6. Back in Citrix Studio, click the Continue database configuration and Site setup button.
  7. In the Databases page, enter the SQL server name, and instance name, and click Next.

  8. On the Licensing page, enter the name of the Citrix License Server, and click Connect. If you installed Licensing with your Delivery Controller, then simply enter localhost.
  9. If the Certificate Authentication appears, select Connect me, and click Confirm.
  10. Then select your license, and click Next. See CTX223926 How to Configure Multiple License Types within a Single XenApp and XenDesktop Site.
  11. In the Summary page, if your databases are mirrored, each database will show high availability servers, and the name of the Mirror server. Click Finish.

  12. It will take some time for the site to be created.

Second Controller

When building the first Delivery Controller, the SQL scripts might have already included the second Delivery Controller, and thus no special SQL permissions are needed. If the second Delivery Controller has not already been added to the SQL databases, then there are several methods of adding a second Controller to the databases for XenApp/XenDesktop:

  • If you have sysadmin permissions to SQL, let Citrix Studio modify the databases automatically.
  • If you don’t have sysadmin permissions to SQL then use Citrix Studio to generate SQL scripts and send them to a DBA.

To use Citrix Studio to create the SQL Scripts:

  1. On the first Delivery Controller, if StoreFront is installed on the Controller, then delete the default StoreFront store (/Citrix/Store), and recreate it with your desired Store name (e.g. /Citrix/CompanyStore).
  2. On the second Delivery Controller machine, install Delivery Controller as detailed earlier.
  3. After installation, launch Studio on the second controller, and click Connect this Delivery Controller to an existing Site.
  4. Enter the name of the first Delivery Controller, and click OK.
  5. If you don’t have full SQL permissions (sysadmin), click No when asked if you want to update the database automatically.
  6. Click Generate scripts.
  7. A folder will open with six scripts. If not mirroring, then the top three scripts need to be sent to a DBA. If mirroring, send all six.
  8. On the SQL Server, open one of the .sql files.

  9. Open the Query menu, and click SQLCMD Mode.
  10. Then execute the XenDesktop script.
  11. If SQLCMD mode was enabled properly, then the output should look something like this:
  12. Repeat for the remaining script files.
  13. Back in Citrix Studio, click OK.
  14. In Citrix Studio, under Configuration > Controllers, you should see both controllers.

Studio – Slow Launch

From B.J.M. Groenhout at Citrix Discussions: The following adjustments can be made if Desktop Studio (and other Citrix management Consoles) will start slowly:

  • Within Internet Explorer, go to Tools – Internet Options – Tab Advanced – Section Security, and uncheck the option Check for publisher’s certificate revocation

After adjustment Desktop Studio (MMC) will be started immediately. Without adjustment it may take some time before Desktop Studio (MMC) is started.

Registry setting (can be deployed using Group Policy Preferences):

  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\WinTrust\Trust Providers\Software Publishing
    • State“=dword:00023e00

Concurrent Logon Hard Limit

From Samuel Legrand XenApp 7.14 – (Really) Manage a DR! – Citrix Policies has a setting called Concurrent Logon Tolerance. However, it is not a hard limit, meaning once the limits are reached, it continues to let users connect. You can configure the Controllers to make it a hard limit by setting the following registry value:

  • HKLM\Software\Policies\Citrix\DesktopServer
    • LogonToleranceIsHardLimit (DWORD) = 1

Local Host Cache

If you have 10,000 or fewer VDAs per zone (up to 40,000 VDAs per multi-zone site/farm), you can enable Local Host Cache (LHC) instead of Connection Leasing. LHC allows new sessions to be started even if SQL database is unavailable. VDA limits for LHC are higher in 7.16 than previous versions of XenApp/XenDesktop.

From Local Host Cache sizing and scaling at Citrix Docs:

  1. For LHC LocalDB, assign the Controller VMs a single socket with multiple cores.
  2. Add two cores for LHC.
  3. Add at least three more Gigs of RAM and watch the memory consumption.
  4. Since there’s no control over LHC election, ensure all Controllers have the same specs.
  5. The Docs article has scripts for monitoring LHC performance.

From XenApp 7.12, LHC and a reboot at Citrix Discussions:

  • If the rebooted DDC is the elected one, a different DDC will take over (causing registration storm) and when the DDC gets back, it will take over brokering causing second registration storm. Site will sort itself out and all will work.
  • If the rebooted DDC is not the elected one, it will not impact any functionality.
  • If you turn the DDC down when site is working, and start it during outage, LHC will not trigger on that machine. This DDC will not impact the LHC unless it would become the elected one. In that scenario it will take control, however not start LHC and resources would not be available.

Trentent Tye at Citrix XenDesktop/XenApp 7.15 – The local host cache in action has a video showing LHC in action.  💡

As mentioned by Citrix Docs, make sure PowerShell Execution Policy is set to RemoteSigned, Unrestricted, or Bypass.

If you did a fresh install of 7.17, then Local Host Cache should be enabled by default. You can run Get-BrokerSite to confirm. (run asnp citrix.* first).

If not enabled, you can run some PowerShell commands to enable Local Host Cache:

asnp citrix.*
Set-BrokerSite -ConnectionLeasingEnabled $false
Set-BrokerSite -LocalHostCacheEnabled $true

George Spiers Local Host Cache XenApp & XenDesktop 7.12 shows the Event Log entries when LHC is enabled.

Database Maintenance

Enable Read-Committed Snapshot

The XenDesktop Database can become heavily utilized under load in a large environment. Therefore Citrix recommends enabling the Read_Committed_Snapshot option on the XenDesktop databases to remove contention on the database from read queries. This can improve the interactivity of Studio and Director. It should be noted that this option may increase the load on the tempdb files. See Citrix article CTX137161 How to Enable Read-Committed Snapshot in XenDesktop for configuration instructions.

Change Database Connection Strings

Sometimes the database connection strings need to be modified:

  • When moving the SQL databases to a different SQL server
  • For AlwaysOn Availability Groups, to add MultiSubnetFailover to the SQL connection strings
  • For SQL mirroring, to add Failover Partner to the SQL connection strings

From Citrix Docs Update database connection strings when using SQL Server high availability solutions: Citrix offers several PowerShell scripts that update XenApp and XenDesktop database connection strings when you are using SQL Server high availability database solutions such as AlwaysOn and mirroring. The scripts, which use the XenApp and XenDesktop PowerShell API, are:

  • DBConnectionStringFuncs.ps1: The core script that does the actual work. This script contains common functions that the other scripts use.
  • Change_XD_Failover_Partner_v1.ps1: Updates (adds, changes, or removes) the failover partner. This script prompts for the failover partner location (FQDN) for each database. (Providing a blank failover partner removes the failover partner. You can also use the ClearPartner option to remove a partner.) Do not set the failover partner to the same location as the principal database server.
  • Change_XD_To_ConnectionString.ps1: Uses the provided connection strings to update the connection strings to the databases. This script ensures that certain Citrix services are up and running, and then updates those services in the correct order on all Controllers in the site. Enclose connection string information for each database in quotes.
  • Change_XD_To_MultiSubnetFailover.ps1: Toggles the addition and removal of MultiSubnetFailover=true. If you use AlwaysOn Availability Groups, Microsoft recommends that the connection string include MultiSubnetFailover=true. This option speeds up recovery when a high availability event occurs, and is recommended for both single and multi-subnet environments. Run this script once to add the option. Run the script again to remove it.
  • Change_XD_To_Null.ps1: Resets all the connection strings on the localhost because something has gone wrong. By resetting the connection strings to null, this script places the Controller into an “initial” state. If you run Studio after running this script, you’ll be asked if you want to create a site or join an existing site. This is useful if something has gone wrong and a reset is needed. After the reset, you can try again to set the connection strings.

CTX140319 How to Migrate XenDesktop Database to New SQL Server has the correctly ordered list of PowerShell commands to change the database connection strings. Make sure PowerShell is running as administrator before running these commands.

Here are the DB Connections that must be changed. This list might be longer than the article. When using the article, make sure you include all of the DB Connections shown below. You can get the full list of database commands by running Get-Command Set-*DBConnection. When changing the DB connections, AdminDBConnection must be the last to be set to NULL, and the first to be configured with the new connection string.

Set-ConfigDBConnection -DBConnection $null
Set-AppLibDBConnection –DBConnection $null    #7.8 and newer
Set-OrchDBConnection –DBConnection $null      #7.11 and newer
Set-TrustDBConnection –DBConnection $null     #7.11 and newer
Set-AcctDBConnection -DBConnection $null
Set-AnalyticsDBConnection -DBConnection $null
Set-HypDBConnection -DBConnection $null
Set-ProvDBConnection -DBConnection $null
Set-BrokerDBConnection -DBConnection $null
Set-EnvTestDBConnection -DBConnection $null
Set-SfDBConnection -DBConnection $null
Set-MonitorDBConnection -DataStore Monitor -DBConnection $null   #Monitoring Database
Set-MonitorDBConnection -DBConnection $null                      #Site Database
Set-LogDBConnection -DataStore Logging -DBConnection $null       #Logging Database
Set-LogDBConnection -DBConnection $null                          #Site Database
Set-AdminDBConnection -DBConnection $null -force

Director Grooming

If XenDesktop is not Platinum Edition, then all historical Director data is groomed at 30 days.

For XenDesktop/XenApp Platinum Edition, by default, most of the historical Director data is groomed at 90 days. This can be adjusted up to 367 days by running a PowerShell cmdlet.

  1. On a Delivery Controller, run PowerShell elevated (as administrator), and run asnp Citrix.*
  2. Run Get-MonitorConfiguration to see the current grooming settings.
  3. Run Set-MonitorConfiguration to change the grooming settings.

View Logging Database

To view the contents of the Logging Database, in Studio, click the Logging node. On the right is Create Custom Report. See Citrix article CTX138132 Viewing Configuration Logging Data Not Shown for more info.

The Logging Database can be queried using Get-LogLowLevelOperation. See Stefan Beckmann Get user who set maintenance mode for a server or client for an example script that uses this PowerShell cmdlet.

Maintain Logging Database

Citrix CTX215069 Troubleshooting and managing Oversized Configuration Logging database: The article’s queries can be used to determine the number of configuration operation types performed by XenDesktop Administrator, and to analyze the content of the Configuration Logging database when it is considered oversized. A grooming query is also provided to delete data older than a specified date.

Export/Import Configuration

Ryan Butler has a PowerShell script that can export configuration from one XenDesktop farm and import it to another.

Kaspars Vilde at XenDesktop/XenApp 7.X Applications – Exporting / Importing at Citrix Discussions has scripts to export published apps from one farm and import to another farm.

Studio Administrators

Full Administrators

  1. In the Studio, under Configuration, click the Administrators node. The first time you access the node you’ll see a Welcome page. Feel free to check the box to Don’t show this again, and then click Close.
  2. On the Administrators tab, right-click, and click Create Administrator.
  3. In the Administrator and Scope page, Browse to a group (e.g. Citrix Admins) that will have permissions to Studio and Director. These groups typically have access to all objects, so select the All scope. Alternatively, you can create a Scope to limit the objects. Click Next.
  4. On the Role page, select a role, and then click Next. For example:
    • Full Administrator for the Citrix Admins group
    • Help Desk Administrator for the Help Desk group
    • Machine Catalog Administrator for the desktop team
  5. In the Summary page, click Finish.

Help Desk

  1. In the Studio, under Configuration, click the Administrators node. On the Administrators tab, right-click, and click Create Administrator.
  2. In the Administrator and Scope page, Browse to a Help Desk group that will have permissions to Studio and Director. Select the All scope. And click Next.
  3. On the Role page, select the Help Desk Administrator role, and then click Next.
  4. In the Summary page, click Finish.
  5. When administrators in the Help Desk role log into Director, all they see is this.

    To jazz it up a little, add the Help Desk group to the read-only role.
  6. Right-click the Help Desk Administrator, and click Edit Administrator.
  7. Click Add.
  8. In the Scope page, select a scope, and click Next.
  9. In the Role page, select Read Only Administrator, and click Next.
  10. In the Summary page, click Finish.
  11. Then click OK. Now Director will display the dashboard.

Customer Experience Improvement Program

XenApp/XenDesktop 7.17 enables CEIP by default. If desired, you can disable it in Citrix Studio:

  1. On the left, go to the Configuration node.
  2. On the right, switch to the Product Support tab.
  3. Click End.
  4. Click Yes.

Citrix Studio 7.17 collects data for Google Analytics. You can disable this in the registry at HKLM\Software\Citrix\DesktopStudio\GAEnabled = 0.

Each XenApp/XenDesktop component has a separate configuration for disabling Customer Experience Improvement Program:

vCenter Connection

XenDesktop uses an Active Directory service account to log into vCenter. This account needs specific permissions in vCenter. To facilitate assigning these permissions, create a new vCenter role and assign it to the XenDesktop service account. The permissions should be applied at the datacenter or higher level.

Import vCenter Root Certificate

If the vCenter certificate is valid and trusted, then you can skip to the Hosting Resource section.

For newer versions of vCenter, you can import the root certificate that signed the vCenter Server/Appliance certificate.

  1. Point your browser to the root path of the vCenter Server URL.
  2. On the bottom right, click Download trusted root CA certificates.
  3. Extract the downloaded files.
  4. Go to \certs\win.
  5. Sort the files by date, and double-click the newest .crt file.
  6. On the General tab, click Install Certificate.
  7. In the Welcome to the Certificate Import Wizard page, change the Store Location selection to Local Machine, and click Next.
  8. In the Certificate Store page, click Browse.
  9. Select Trust Root Certification Authorities, and click OK.
  10. In the Completing the Certificate Import Wizard page, click Finish.
  11. If you close your browser and reopen it, and then go to the vCenter URL, there should no longer be any certificate errors.
  12. Skip to the Hosting Resource section.

Import vCenter Certificate

If the vCenter certificate is valid and trusted, then you can skip to the Hosting Resource section.

Alternatively, you can import the actual vCenter Server certificate (instead of the root). This is the only option for older self-signed vCenter certificates.

Newer versions of XenDesktop have the ability to import the vCenter certificate thumbprint into the database so every Controller trusts it. However, it is difficult to update the thumbprint whenever the vCenter certificate changes. It might instead be more reliable to use the older method of configuring the Trusted People store on the Delivery Controllers. Whenever the vCenter certificate is changed, you’ll need to repeat these steps.

  1. Get the vCenter certificate.
    1. Open a browser and point it to the vCenter URL. Note: this procedure to get the certificate won’t work in Internet Explorer.
    2. If Google Chrome, press <F12> to open the Developer Tools.
    3. On the top right, click the two right arrows to show more tabs, and click Security.
    4. On the Security tab, click View certificate.
    5. On the Details tab, click Copy to File.
    6. In the Welcome to the Certificate Export Wizard page, click Next.
    7. In the Export File Format page, either format will work. Click Next.
    8. In the File to Export page, browse to a new file, and click Next.
    9. In the Completing the Certificate Export Wizard page, click Finish.
  2. Simply run certlm.msc. This opens the MMC console with the Certificates snap-in already added and pointing to Local computer.
  3. On the left, right-click the Trusted People node, expand All Tasks, and click Import.
  4. In the Welcome to the Certificate Import Wizard page, click Next.
  5. In the File to Import page, browse to the certificate you saved earlier, and click Next.
  6. In the Certificate Store page, click Next.
  7. In the Completing the Certificate Import Wizard page, click Finish.
  8. Click OK to acknowledge that the import was successful.
  9. Repeat these steps on the second Controller. It is important that you import the certificate on both Controllers before adding the Hosting Resource.
  10. If you open Internet Explorer and browse to the vCenter Server, there should be no certificate errors.

Hosting Resources

A Hosting Resource = vCenter + Cluster (Resource Pool) + Storage + Network. When you create a machine catalog, you select a previously defined Hosting Resource, and the Cluster, Storage, and Network defined in the Hosting Resource object are automatically selected. If you need some desktops on a different Cluster+Storage+Network, then you’ll need to define more Hosting Resources in Studio.

  1. In Studio, expand Configuration and click Hosting. Right-click it, and click Add Connection and Resources.
  2. In the Connection page, for Connection type, select VMware vSphere.
  3. Notice there’s a Learn about user permissions blue link to an article that describes the necessary permissions.
  4. Enter https://vcenter01.corp.local/sdk as the vCenter URL. The URL must contain the FQDN of the vCenter server.
  5. Enter credentials of a service account that can log into vCenter.
  6. In the Connection name field, give the connection a name. Typically, this matches the name of the vCenter server.
  7. If you are not using Machine Creation Services, and instead only need the vCenter connection for machine power management, change the Create virtual machines using selection to Other Tools. If you intend to use MCS, leave it set to Studio Tools.
  8. Click Next.

  9. In the Storage Management page, click Browse, and select a vSphere cluster.
    • Note: as detailed at CTX223662, make sure there’s no comma in the datacenter name.
  10. Select Use storage shared by hypervisors.
  11. If you have sufficient disk space on each ESXi host, also select Optimize temporary data on available local storage. From Mark Syms at XA 7.9 MCS with RAM Caching at Citrix Discussions: “If you use just MCS caching to local storage then the VM is not agile at all and cannot be moved even when powered off as it has a virtual disk permanently associated with a single host.”
  12. From Martin Rowan at XA 7.9 MCS with RAM Caching at Citrix Discussions: for the temporary cache disk, “Don’t format it, the raw disk is what MCS caching uses.”
  13. Click Next.
  14. In the Storage Selection page, OS and Personal vDisk must be selected on at least one datastore. For maximum flexibility, only select one datastore. To select additional datastores, run this wizard again to create a separate Hosting Resource.
  15. If you selected the temporary data on local storage option, on the bottom, click Select, and choose the datastores you want to use for disk caching. By default, all local datastores are selected. Click Next when done.
  16. In the Network page, enter a name for the hosting resource. Since each hosting resource is a combination of vCenter, Cluster, Network, and Datastores, include those names in this field (e.g. vCenter01-Cluster01-Network01-Datastore01).
  17. Select a network and click Next.
  18. In the Summary page, click Finish.
  19. If you have multiple datastores for your VDAs, run the wizard again.
  20. You can use the existing vCenter connection.
  21. This time, select a different datastore.
  22. Give it a name that indicates the chosen datastore.
  23. When you create a Catalog, select the Hosting Resource for the datastore where you want the VDAs to be placed. Create additional Catalogs for each datastore. You can then combine the Catalogs into a single Delivery Group.
  24. Later in the Catalog wizard, you’re given an option to enable caching and select a cache size. This is similar to Provisioning Services option “Cache in RAM with overflow to disk”.
  25. If you rename Storage, Network, or Datacenters, see Citrix CTX225019 XA/XD 7.13: Renaming Storage, Network or Datacenters When Used With MCS or PVS. Either run Update-HypHypervisorConnection -LiteralPath "XDHyp:\Connections\MyConnection", or right-click the Hosting Resource and click Edit Storage. You can cancel the wizard.

Citrix License Server

Upgrade License Server

XenApp/XenDesktop 7.18 comes with 11.15.0.0 build 24100.

If you have a standalone Licensing Server, upgrade it to Citrix Licensing 11.15.0.0 build 24100, if it isn’t already.

  1. Go to the downloaded Citrix Licensing 11.15.0.0 build 24100, and run CitrixLicensing.exe.

  2. If you see the Subscription Advantage Renewal page, make a selection, and click Next.
  3. In the Upgrade page, click Upgrade.
  4. Click Finish.
  5. If you go to Programs and Features, it should now show version 11.15.0.1 build 24100.
  6. If you login to the license server web console, on the Administration tab…
  7. It shows it as version 11.15.0.1 build 24100.
  8. You can also view the version in the registry at HKLM\Software\Wow6432Node\Citrix\LicenseServer\Install.

Citrix Licensing Manager

Newer versions of License Server come with a new management web site. Citrix seems to be slowly moving all functionality to the new web site.

  1. From the Start Menu, run Citrix Licensing Manager. Or go to https://<My_Licensing_Server>:8083
  2. You might be prompted to login.

    • To eliminate this login, add the License Server URL to the Local Intranet zone.
  3. This web site will be used for some of the following procedures.
  4. If you click the gear icon on the top right…
  5. You can add License Server Administrators.

Activate Citrix License

The easy way to install and activate a Citrix license is through Citrix Studio:

  1. In Citrix Studio, expand Configuration, right-click Licensing, and click Allocate Licenses.
  2. Enter the LA- license code, and click Show.
    • You can find your LA- code at http://mycitrix.com, click All Licensing Tools, and click View Licenses.
  3. Then click the Allocate licenses button.

    • Another method of allocating licenses is in the new Licensing Manager at https://MyLicenseServer:8083.
  4. After licenses are installed, right-click the Licensing node, and click Edit Product Edition
  5. Change the edition to match your licenses. If you see both XenDesktop and XenApp licenses, you must select XenDesktop. If you see both Concurrent and User/Device, then you must select User/Device. Click OK when done.
  6. XenDesktop 7.14 and newer support mixed licensing in a single site/farm. See the following:

License Server CEIP

11.14.1.1 build 19005 and newer enables CEIP by default. This can be disabled in the Citrix Licensing Manager (https://MyLicenseServer:8083) by clicking the gear icon.

Switch to the Usage and Statistics tab, and make a selection in the Share usage statistics with Citrix section.

Citrix License Management Service

Version 11.14.0.1 and newer include the Citrix License Management Service. This service helps you avoid prohibited practices:

  • Duplication of licenses outside a Disaster Recovery (DR) environment
  • Use of legacy licenses for new product versions
  • Use of rescinded licenses

Citrix License Server Monitoring

Citrix Licensing 11.13.1 and newer has historical usage reporting:

  1. Run Citrix Licensing Manager from the Start Menu. Or use a browser to connect to https://MyLicenseServer:8083
  2. On the Historical Use tab, use the drop-down menus to select a license type, select dates, and export to a .csv file.
  3. The Update Licenses tab lets you check for renewals and download them.
  4. On the top right is a gear icon where you can set the historical retention period.

    1. On the Usage and Statistics tab…
    2. Scroll down and find the Historical Use section.

Andrew Morgan – New Free Tool: Citrix Director Notification Service: The Citrix Director Notification service sits on an edge server as a service (or local to the delivery controller) and periodically checks the health of:

  • Citrix Licensing.
  • Database Connections.
  • Broker Service.
  • Core Services.
  • Hypervisor Connections.

And if any of these items fall out of bounds, an SMTP alert is sent to the mailbox of your choice for action. The tool will also send “All Clear” emails when these items are resolved, ensuring you are aware when the service has resumed a healthy state.
