Change Log

Workspace app Versions

Citrix Workspace app uses a YYMM (year/month) versioning format, of which version 2311.1 (23.11.1.140) is the newest. See Citrix Docs for the list of new features, some of which only apply to Citrix Cloud.

Workspace app 2311 and newer have a new installer interface. 

Workspace app 2009 and newer have the new Citrix logo.

Workspace app 1912 and newer support App Protection. It’s available in LTSR version 2203 and the Current Release 2311.1 version. Workspace app 2303 and newer automatically install the App protection components with an option to start them after installation. Older Workspace apps have an option to install App protection and if you don’t select this and later want App protection then you must uninstall Workspace app and reinstall it.


  • See App Protection at Citrix Docs to enable App protection for the authentication screen. Workspace app 2305.1 and newer automatically start it for authentication if you have selected the Start App Protection check box during installation.

The only supported LTSR (Long Term Service Release) version of Workspace app is version 2203. Its latest cumulative update is 6 Update 1

  • The newest Workspace app versions contain many Teams optimization enhancements.
  • The LTSR versions of Workspace app do not support Browser Content Redirection (BCR) because the embedded browser is not included in the LTSR Workspace app.
  • Download LTSR version 22.03.6001,

Workspace app Modules

The Workspace app installer deploys multiple modules. Here are the important ones:

  • ICA Engine (wfica.exe) – process that uses the ICA protocol to connect to published apps and desktops.
  • Self-Service (selfservice.exe) – gets icons from StoreFront and displays them in a Window. When an icon is clicked, Self-service passes the ICA file to the ICA Engine to establish a connection.
  • Single Sign-on (SSON) for ICA (ssonsvr.exe) – captures user credentials and submits them to VDAs after an ICA connection is established
  • Workspace Auto-Update (CitrixReceiverUpdater.exe) – Notifies users of Workspace app updates. The most recent name for this component is Citrix Workspace Update.

Custom ICA files are no longer supported. However, Ryan Butler has created a script that asks StoreFront for an ICA file. Explicit credentials are supported. Find the script at Github.

Workspace app Discovery and Beacon Process

If you are using Workspace app’s built-in user interface (instead of a web browser), then Workspace app first prompts you to perform discovery, which is also called Add Account.

The Citrix logo changed in Workspace app 2009 and newer.

The Add Account wizard changed in Workspace app 2108 and newer. Enter a StoreFront FQDN, a Citrix Gateway FQDN, or Citrix Cloud Workspace FQDN. Just enter the FQDN. There’s no need to enter https or a path.

Workspace app will contact the FQDN and request download of the StoreFront Provisioning File.

  • If you entered a StoreFront FQDN, then Workspace app will download the Provisioning File directly from the StoreFront server.
  • If you entered a Gateway FQDN, then Gateway will first prompt the user to authenticate. After authentication, Gateway will connect to its configured Account Services address, and download the Provisioning File from StoreFront. The Account Services address is configured in the NetScaler Gateway Session Profile on the Published Applications tab.

If your StoreFront server is configured with multiple stores, then the user will be prompted to select a store. Unfortunately, there’s no configuration option in NetScaler Gateway to force a particular store.

The Provisioning File downloaded from StoreFront is an XML document containing values for several items configured in the StoreFront console. You can export the Provisioning File from the StoreFront console by right-clicking a Store.

The ReceiverConfig.cr Provisioning File looks something like this:

Here are the values in the Provisioning File:

  • Address – the Base URL configured in StoreFront Console
  • Internal Beacon – as configured in StoreFront Console. This can be the Base URL, or a manually specified URL.
  • External Beacons – as configured in StoreFront Console
  • Gateways – as configured in StoreFront Console. If there are multiple Gateways, when enabling Remote Access on the Store, then only one Gateway is selected as Default
  • SRID – Store ID. An important value to consider for multi-datacenter configurations. The SRID is set when the Store is created. It can also be changed by editing C:\inetpub\wwwroot\Citrix\Roaming\web.config.

Workspace app reads the Provisioning File, and configures itself by inserting the file’s contents into the user’s registry. The values are located under HKCU\Software\Citrix\Dazzle\Sites and HKCU\Software\Citrix\Receiver\SR. If you performed discovery through NetScaler Gateway, notice that the internal Base URL is added to the user’s registry.

Once Workspace app is configured, it then performs the following steps:

  1. Attempt to connect to the Internal Beacon.
  2. If the Internal Beacon is reachable, connect directly to the StoreFront Base URL (Address).
  3. If the Internal Beacon is not reachable:
    1. Attempt to connect to the External Beacons. If the External Beacons are not reachable, then stop attempting to connect.
    2. Connect to the Gateway address configured in the Provisioning File. If there is more than one Gateway, connect to the Gateway that is marked as the Default.

Here are some interesting notes on this connection process:

  • The FQDN you entered during Discovery has absolutely nothing to do with how Workspace app connects to StoreFront or Gateway. The actual connection process is controlled by the contents of the Provisioning File, not the Discovery address.
  • If the Provisioning File has multiple Gateways defined, Workspace app uses whichever Gateway is marked as Default. Workspace app completely ignores whatever Gateway FQDN you entered during Discovery. To use a non-default Gateway, the user must manually select the other Gateway in Workspace app’s Advanced Preferences.

In StoreFront Console, if any configuration changes are performed that affect the Provisioning File, it takes an hour for Workspace apps to reconfigure themselves automatically. Or users can remove Accounts and re-add (or Reset Citrix Workspace) so that the updated Provisioning File is imported.

Here are some additional methods of performing Workspace app Discovery:

  • After exporting the Provisioning File from StoreFront Console, distribute it to users, and ask them to double-click it.


  • After logging in to Receiver for Web (StoreFront), at the top right, click the username, and click Activate. This downloads the receiverconfig.cr file, which is identical to the one you can export from StoreFront Console. The user then must run the downloaded file.

Virtual Monitors

In Workspace app 1812 and newer, when connected to a published desktop on a single monitor, you can split the screen into virtual monitors. This feature is intended for large 4K monitors.

  • In the desktop toolbar at the top of the screen, click Preferences.
  • Switch to the Monitor Layout tab.
  • On the bottom, select Horizontal or Vertical, then click somewhere in the blue box to draw a line. The single monitor will be split along this line. You can set different DPI for each portion of the virtual display.
  • Right-clicking one of the split sections changes that section to the primary display.
  • Click OK when done.
  • In the toolbar, click Window to resize it to a window, and then click Full Screen to cause your virtual monitor configuration to take effect.

Uninstall Old Clients

Workspace app installer can do a force uninstall of old clients before installing the new version:

  • In Workspace app 2309 and newer, run CitrixWorkspaceApp.exe /CleanInstall /Silent
  • In Workspace app 1909 and newer, run CitrixWorkspaceApp.exe /ForceInstall /Silent.
  • In Workspace app 1908 and older (including Receiver), run CitrixWorkspaceApp.exe /RCU /Silent or CitrixReceiver.exe /RCU /Silent.

Citrix CTX325140: How to Remove Client Files Remaining on System after Uninstalling Receiver for Windows.

Installation and Configuration

Administrator privileges – Administrator privileges are required to install any missing prerequisites.

Internet required – Recent versions of Workspace app (e.g., 2311.1) download and install Microsoft Edge WebView2 Runtime, .NET Desktop Runtime 6.0.20, .NET Framework 4.8, and Visual C++. Internet access is required for the Workspace app installer to download these install files. Or there’s also an Offline Installer for Workspace app 2309 and newer.

.NET Desktop Runtime 6.0.20 – Workspace app 2309 and newer will install x86 .NET Desktop Runtime 6.0.20 if it’s not already installed.

This section contains a summary of all common command line switches, registry keys, and policy settings for Workspace app.

Workspace app 2203 LTSR CU2 and Workspace app 2212 and newer fix security vulnerabilities.

CitrixWorkspaceApp.exe current release version 2311.1 or LTSR version 2203 CU6 Update 1 (aka 22.03.6001) can be installed by simply double-clicking it.

  • LTSR Workspace app does not support Browser Content Redirection.
  • Workspace app 2006 and newer do not support Windows 7.
  • Workspace app 2206 and newer enable DPI Matching by default. DPI Matching can be disabled through client-side group policy, or in the Advanced Preferences in Workspace app 2212 and newer. DPI Matching prevents connections to CVAD 7.15. Multi-session VDAs with version 1912, by default, have DPI Matching disabled, but can be enabled in the VDA’s registry. See CTX460068 for details.

  • Workspace app 2311 and newer have a new interface for installation.


Administrator vs non-administrator

  • Non-administrator – If a non-administrator installs Workspace app, then each non-administrator that logs in to the same workstation will have to reinstall Workspace app.
    • Non-administrator installations are installed to %USERPROFILE%\AppData\Local\Citrix\ICA Client for each user.
  • Administrator – If CitrixWorkspaceApp.exe is installed using an administrator account. then the Workspace app only needs to be installed once.
    • Administrator installations are installed to C:\Program Files (x86)\Citrix\ICA Client.
    • Administrator installations of Workspace app 1912 and newer can be manually upgraded by non-administrators by clicking Check for Updates. Older versions cannot be upgraded by non-administrators.
  • Conflicts – If an administrator install of Workspace app is performed on a machine that has non-administrator installs of Workspace app, then the two installations will conflict. Best option is to uninstall non-admin Workspace app and Receiver before installing admin Workspace app. Otherwise, the user’s profile probably has to be reset before Workspace app is functional again.

Global App Configuration Service

Global App Configuration Service (GACS) is a Citrix Cloud service that can push configurations to Workspace app clients. This Citrix Cloud service is now available to all on-premises customers even if you don’t own any Citrix Cloud entitlements.

  1. Login to https://citrix.cloud.com. If you don’t have a Citrix Cloud account, then login using your Citrix.com account credentials and it will create a Citrix Cloud account.
  2. Use the top left hamburger menu to go to Workspace Configuration.
  3. Switch to the tab named App Configuration.
  4. Click Switch URL.
  5. Near the bottom, click Claim URL.
  6. Click Add URL to add your on-premises StoreFront/Gateway URL. See Citrix Docs for details. GACS uses this URL to determine which Workspace app clients should receive the settings that you configure.
  7. Back in the App Configuration page, you can now configure Workspace app settings as desired. Workspace apps that have stores under the claimed URL will then receive these settings.

Auto-Update

Workspace app supports auto-update.

Some notes:

  • If Workspace app 1912 or newer is installed as administrator, then non-administrators can click Check for Updates to manually update Workspace app. To prevent this, use group policy to disable Citrix Workspace Updates.

    • Older versions of Workspace app cannot be upgraded by non-administrators.
  • If Workspace app is installed on a VDA, auto-update is automatically disabled. This includes Remote PC.
  • Auto-update can be limited to LTSR updates only.
  • Auto-update is configurable through several mechanisms: group policy, StoreFront, Workspace app GUI, installer command line. See Configuring Citrix Workspace Updates at Citrix Docs.
  • Workspace app 2107 and later let users select an Update channel.

  • See George Spiers Citrix Receiver for Windows Auto-Update.

Auto-update is configured using Workspace app group policy under the Citrix Workspace Updates, or Auto-Update node.


Or use Global App Configuration Service.

Workspace app Splash Screen

Workspace app shows a Splash Screen on first launch with the text “Citrix Workspace app extends the capabilities of Citrix Receiver”.

To prevent this splash screen, set the following registry value: (source = Dennis Span on Twitter)

  • Key = HKEY_CURRENT_USER\SOFTWARE\Citrix\Splashscreen
    • Value (REG_SZ) = SplashscreenShown = 1

Add Account Wizard

After installation, Workspace app will launch and ask you to add an account. If Workspace app, notice the checkbox Do not show this window automatically at logon.

FTU (First Time Use aka Add Account Wizard) will be displayed only if a store is not configured. If a store is already configured via command line, GPO, or Citrix Studio, then FTU screen will not be available after installation. Otherwise, FTU can be suppressed by doing one of the following:

  • Rename CitrixWorkspaceApp.exe to CitrixWorkspaceAppWeb.exe.
  • Install using a command line switch:
    • CitrixWorkspaceApp.exe /ALLOWADDSTORE=N
  • Set the registry value: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Citrix\EnableFTU=dword:00000000 (or EnableX1FTU =dword:0)
  • Disable the EnableFTU policy setting in Receiver.admx.
  • Change Registry values post installation to suppress the Add Account window. Under HKLM\Software\Wow6432Node\Citrix\Dazzle, set AllowAddStore value to N.
  • Set the registry value: HKEY_LOCAL_MACHINE\Software\Citrix\Receiver\NeverShowConfigurationWizard (REG_SZ) = true
  • Also see Suppressing Add Account dialog at Citrix Docs.

Discover Hidden Stores

When Workspace app is first launched, it must perform Discovery, which is the process of downloading the .xml provisioning file from StoreFront. Discovery is performed by entering a StoreFront FQDN or Gateway FQDN. To discover a hidden store (a store that’s not advertised), add ?StoreName to the end of the FQDN. CTX214819 How to configure Receiver to a Store that is not advertised.

Deploy Workspace app using Active Directory

To deploy Workspace app using Active Directory, configure a GPO with a computer startup script that runs the Workspace app installer executable. Citrix provides sample scripts that can be downloaded from one of the Workspace app download pages (Workspace app current release version 2311.1, or LTSR version 2203 CU6 Update 1 (aka 22.03.6001)), by expanding Downloads for Admins (Deployment Tools).

Also see CTA Dennis Span Citrix Receiver unattended installation with PowerShell.

Change Workspace App’s Store Configuration, including Reset Citrix Workspace

You can change Workspace app’s configured Store/Account with a couple command lines:

"C:\Program Files (x86)\Citrix\ICA Client\SelfServicePlugin\SelfService.exe" -deleteproviderbyname Corporate 
"C:\Program Files (x86)\Citrix\ICA Client\SelfServicePlugin\SelfService.exe" -init -createprovider Corporate https://storefront.corp.com/Citrix/Store/discovery

 

It is sometimes necessary to Reset Citrix Workspace by right-clicking the Workspace app systray icon, clicking Advanced Preferences, and clicking the Reset link. You can do this from the command line by running "C:\Program Files (x86)\Citrix\ICA Client\SelfServicePlugin\CleanUp.exe" -cleanUser -silent. See CTX140149 How to Reset Receiver Using the Command Line.

Workspace app Group Policy ADMX Template

Many of the Workspace app configuration settings must be configured in group policy. These Workspace app settings are only available after installing the GPO templates.

Alternatively, Citrix Cloud customers can use Global App Configuration Service to configure Workspace app. Today it’s a REST API, but Citrix has started adding a GUI at Workspace Configuration > App Configuration.

For GPO configuration:

  1. From a machine that has Workspace app installed, find the .admx and .adml files in the C:\Program Files (x86)\Citrix\ICA Client\Configuration.
    • You can also download the ADMX files from one of the Workspace app download pages (Workspace app current release version 2311.1, LTSR version 2203 CU6 Update 1 (22.03.6001)), by expanding Downloads for Admins (Deployment Tools).
  2. Copy the CitrixBase.admx and receiver.admx files. Also copy the en-US folder. In Workspace app, the files are still named receiver.admx.
  3. Go to your domain’s SYSVOL share and in the Policies folder look for a PolicyDefinitions folder. If one exists, paste the .admx file directly into the PolicyDefinitions folder. If this folder doesn’t exist in SYSVOL, instead copy the .admx file to C:\Windows\PolicyDefinitions. Overwrite any existing Receiver ADMX files.
  4. The GPO settings can then be found at one of the following:
    • Computer Configuration > Policies > Administrative Templates > Citrix Components > Citrix Workspace
    • Computer Configuration > Policies > Administrative Templates > Citrix Components > Citrix Receiver
  5. For example, you can disable Customer Experience Improvement Program (CEIP) from here.
  6. See https://www.carlstalhood.com/delivery-controller-cr-and-licensing/#ceip for additional places where CEIP is enabled.
  7. Workspace app 1905 and newer has a setting to Disable sending data to 3rd party (e.g., Google Analytics).
  8. Workspace app 1905 and newer let you disable embedded browser caching.
  9. Workspace app 1905 and newer have NetScaler LAN Proxy under Network routing > Proxy.
  10. Workspace app 1808 and newer have User authenticationSingle Sign-on for NetScaler Gateway.
  11. Citrix Workspace Updates, (aka AutoUpdate) can be configured using group policy. See Configuring Citrix Workspace Updates at Citrix Docs.
  12. Workspace app 1912 and newer can be configured to require in-memory ICA files only. The setting called Secure ICA file session launch is under the Client Engine node. See Citrix Docs for details on in-memory ICA files instead of writing ICA files to disk.
  13. The DPI node has a setting called High DPI that lets you disable DPI matching, which is enabled by default in Workspace App 2206 and newer.

    • Workspace app 2210 and newer let you use the GUI to re-enable High DPI.
    • Native resolution means DPI matching, whereas Yes means force high DPI.
  14. Workspace app has settings to hide Advanced Preferences, enable/disable showing the DPI option, and enable/disable H265.
  15. Workspace app 4.8 and newer have SplitDevices GPO setting under Citrix Workspace | Remoting client devices | Generic USB Remoting. See Configuring composite USB device redirection at Citrix Docs.
  16. Workspace app 2212 and newer by default disable App Protection for the authentication screen and icons list. To enable them, configure User authenticationManage App Protection and SelfServiceManage App Protection.

  17. Workspace app 2303 and newer have Anti-DLL Injection for App Protection. It is disabled by default. Enable it in a GPO at Citrix Components | Citrix Workspace | App Protection | Anti-DLL Injection. See Citrix Docs for details.

Pass-through Authentication

Citrix blog post – A Comprehensive Guide to Enabling Pass-Through Authentication with XenDesktop 7.5

  1. Run the command
    Set-BrokerSite -TrustRequestsSentToTheXmlServicePort $True from a Windows PowerShell command prompt on a Delivery Controller.

  2. Login to the PC as an administrator.
  3. If installing Workspace app, as an administrator, during installation, on the Enable Single Sign-on page, check the box next to Enable Single Sign-on. Then finish the installation.

  4. To verify that SSON is installed, go to C:\Program Files (x86)\Citrix\ICA Client and look for the file ssonsvr.exe.
  5. And if you open regedit and go to HKLM\SYSTEM\CurrentControlSet\Control\NetworkProvider\Order, you should see PnSson in the ProviderOrder.
  6. Install the receiver.admx (and .adml) template into PolicyDefinitions if you haven’t already.
  7. Edit a GPO that is applied to the client PCs where the Workspace app is installed.
  8. Go to Computer Configuration > Policies > Administrative Templates > Citrix Components > Citrix Workspace.
  9. Expand Citrix Workspace and click User authentication.
  10. On the right, double-click Local user name and password.
  11. Select Enabled and then check the box next to Allow pass-through authentication for all ICA connections. Click OK.
  12. In Workspace app 1808 and newer, you can enable Single Sign-on for NetScaler Gateway.
  13. Ensure that the internal StoreFront FQDN is in the Local Intranet zone in Internet Explorer. You can use a GPO to configure this on the client side.
  14. Local Intranet zone should have Automatic logon only in Intranet zone enabled.
  15. For Windows 11 and newer, make sure the GPO setting Enable MPR notifications for the System is not enabled at Computer Configuration | Policies | Administrative Templates | Windows Components | Windows Logon Options. Make sure HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System\EnableMPRNotifications is not set to 0 on the Workspace app machine.
  16. Logoff Windows and log back on. In Task Manager you should now see ssonsvr.exe. This won’t appear unless you logoff and log back on.
  17. If Workspace app won’t connect or is slow to enumerate icons, then you might have to disable Automatically detect settings in IE.
  18. Right-click the Workspace app icon and click Advanced Preferences.
  19. Click Configuration Checker.
  20. Check the box next to SSONChecker and click Run.
  21. The lines with red x will indicate the issue and corrective action.

StoreFront Accounts

You can use a client-side GPO to add a store (Account) to Workspace app Self-Service.

  1. Install the receiver.admx (and .adml) template into PolicyDefinitions if you haven’t already.
  2. Edit a GPO that applies to endpoint devices that have Citrix Workspace app installed.
  3. Go to Computer Configuration > Administrative Templates > Policies > Citrix Components > Citrix Workspace > StoreFront.
  4. On the right, double-click NetScaler Gateway URL/StoreFront Accounts List.
  5. Select Enabled, and then click Show.
  6. Enter a store path based on the example shown in the Help box. Workspace app lets you enter a Gateway path. Then click OK.
  7. Note: Gateway paths work in GPO, but might not work when specified in the CitrixWorkspaceApp.exe installation command line.

Published Shortcuts and Reconnect

Citrix CTX200924 How to Customize App Shortcuts with Receiver for Windows

Workspace app has a user interface for setting Shortcut Paths. Right-click the Workspace app systray icon, click Advanced Preferences, and then click Shortcuts and Reconnect, or Settings Option.


From Citrix Docs Configuring application delivery: There are several methods of controlling how Workspace app displays shortcuts on the Start Menu and Desktop as detailed below:

  • Workspace app Registry values
  • receiver.admx GPO Template
  • From StoreFront in C:\inetpub\wwwroot\Citrix\Roaming\web.config
  • Published App Keywords (e.g. prefer).
  • Workspace app and Receiver 4.2.100 and newer supports published app Delivery configuration for adding the shortcut to the desktop. This only works if the app is a Favorite, or if Favorites are disabled, or Mandatory Store.

Under HKLM\Software\Wow6432Node\Citrix\Dazzle (or HKCU\Software\Wow6432Node\Citrix\Dazzle) are several registry values related to shortcuts. Some of the settings only apply if SelfServiceMode is set to False. Here are some common options:

  • SelfServiceMode – set to False so Receiver disables the Self-Service interface and automatically places all published shortcuts on the Start Menu and/or Desktop. More details in Configuring application delivery at Citrix Docs.
  • PutShortcutsOnDesktop – set to True to place every app on the desktop
  • DesktopDir – Workspace app places every shortcut on the desktop so it’s probably best to place them in a folder.
  • StartMenuDir – If there is potentially a conflict between local apps and remote apps, then you should place the Start Menu shortcuts in a folder.
  • PreferTemplateDirectory (with KEYWORDS:prefer=shortcutname) – copies the shortcutname from the template directory to the Start Menu and/or Desktop.

If you import the receiver.admx (and .adml) into the PolicyDefinitions folder, under Computer Configuration > Administrative Templates > Citrix Components > Citrix Workspace (or Receiver) is a node called SelfService.

Disable the Manage SelfServiceMode setting to hide the Workspace app Window.

Enable the Manage App shortcut setting to control placement of shortcuts.

Workspace app and Receiver 4.2.100 and newer have the ability to configure (or disable) Workspace Control using group policy. Enable the setting Control when Citrix Workspace attempts to reconnect to existing sessions and configure it as desired.

Prelaunch

Staring with Receiver 4.2, prelaunch is automatically enabled if Workspace app is installed with SSON enabled. Otherwise, set registry values to enable prelaunch. Receiver 4.2.100 prevents the prelaunch icon from appearing on the Start Menu.

  • HKLM\Software\[Wow6432Node\]Citrix\Dazzle
    • EnablePreLaunch (REG_SZ) = true or false

Additional customizations can be configured at:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Prelaunch

  • Name: State
    • REG_SZ: 0 = disable, 1 = just-in-time pre-launch, 2 = scheduled pre-launch
  • Name: Schedule
    • REG_SZ: HH:MM|M:T:W:TH:F:S:SU where HH and MM are hours and minutes. M:T:W:TH:F:S:SU are the days of the week. For example, to enable scheduled pre-launch on Monday, Wednesday, and Friday at 1:45 p.m., set Schedule as Schedule=13:45|1:0:1:0:1:0:0 . The session actually launches between 1:15 p.m. and 1:45 p.m.
  • Name: UserOverride
    • REG_SZ: 0  = HKLM overrides HKCU, 1 = HKCU overrides HKLM

Device Access Behavior (Client Selective Trust)

When connecting to a XenApp/XenDesktop session, you might see the following:

To configure the default behavior, see the Citrix Knowledgebase article How to Configure Default Device Access Behavior of Receiver, XenDesktop and XenApp. Note: there is a bug fixed in Receiver 4.2.100 and newer.

  1. Download the ADMX file from http://support.citrix.com/article/CTX133565.
  2. Copy the .admx and .adml files to PolicyDefinitions (Sysvol, or C:\Windows).
  3. The .adml file goes in the en-US folder.
  4. Edit a GPO that applies to the endpoint devices that are running Receiver.
  5. Go to Computer Configuration | Policies | Administrative Templates | Citrix Components | Citrix Workspace (or Receiver) |  Citrix Client Selective Trust (x64).
  6. Enable the setting Create Client Selective Trust Keys.

  7. Then expand the regions, and configure the permission settings as desired.

Desktop Lock

As an alternative to Workspace app Desktop Lock, see Transformer in Citrix Workspace Environment Manager.

Use Studio to configure Workspace app Accounts in Published Desktop

In published desktops, Workspace app can be used for placement of shortcuts on the user’s Start Menu and Desktop. Use group policy to hide the common program groups and then use Workspace app to place published applications back on the Start Menu and Desktop based on user’s group membership and subscription preference.

  1. In Citrix Studio, on the left, expand the Configuration node, right-click StoreFront and click Add StoreFront.
  2. Enter a descriptive name for the StoreFront server.
  3. Enter the internal https URL of the load balanced StoreFront servers. Add the path to your store (e.g. /Citrix/Store) and then /discovery on the end of the URL. The full URL would be similar to https://citrix.corp.com/Citrix/Store/discovery. Click OK.
  4. Edit a Delivery Group that has a published desktop and Citrix Workspace app installed.
  5. On the StoreFront page, change the selection to Automatically, using the StoreFront servers selected below, and then check the box next to the StoreFront URL. Click OK. Now when users launch the published desktop, Workspace app will be automatically configured with this URL.

Published Desktop – use Workspace app to control Shortcuts

If you install Workspace app inside a published desktop (Workspace app on a VDA), then Workspace app can get icons from StoreFront and put those icons on the user’s published desktop Start Menu and Desktop. This is an alternative to using a User Experience Management product to control shortcut placement.

Note: Workspace app tends to be slow to create Start Menu shortcuts, so make sure you perform a Proof of Concept to determine how this functionality impacts logon times.

Configuration of Workspace app inside a published desktop is simplified if you have the following minimum versions:

  • Workspace app installed inside the VDA
  • VDA 7.17 or newer
  • StoreFront 3.14 or newer

If you meet these minimum version requirements, then Workspace app installed in the VDA automatically tries to launch published applications on the same local VDA rather than trying to launch them from a different VDA (aka double-hop). This feature is called vPrefer.

Do the following for all versions of Workspace app, VDA, and StoreFront, whether using the Prefer keyword or not:

  1. Make sure Workspace app or Receiver version 4.11 or newer is installed on the VDA.
  2. Install the Workspace app ADMX files if you haven’t already. For vPrefer, make sure they are the ADMX files from Workspace app.
  3. Enable the Group Policy setting Remove common program groups from Start Menu and apply it to non-administrators.
    • This removes all Public (aka All Users) Start Menu shortcuts. Workspace app will re-add the shortcuts based on user group membership.
  4. On the VDA, configure the following Workspace app Registry keys (or corresponding settings in the receiver.admx GPO template):
    • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle\WSCReconnectMode=”0″ so Workspace app doesn’t try to reconnect to the published desktop you’re already running.
    • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle\SelfServiceMode to False. This turns off the Workspace app Self-Service GUI and acts like all icons are subscribed. Otherwise, only subscribed (favorited) icons would be placed on the Start Menu and Desktop.
    • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle\UseCategoryAsStartMenuPath = True. This creates a Start Menu folder based on the published app’s configured Category.
  5. Configure each desired published app to Add shortcut to user’s desktop.

    • Or, configure HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle\PutShortcutsOnDesktop = True to place all icons on the desktop.
  6. To control icon placement, configure the following registry values:
    • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle\StartMenuDir to place published applications in a sub-folder. Note: Windows Server 2012 and Windows 10 and newer only supports a single level of Start Menu folders, so setting this effectively turns off published app categories.
    • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle\DesktopDir to place published applications in a sub-folder on the desktop.
  7. Pass-through authentication:
    1. In a GPO that applies to the VDA, import the receiver.admx file, and set Local user name and password to Enabled. Check the box next to Allow pass-through authentication for all ICA connections.
    2. If you’re using Gateway internally, and if Workspace app 1808 or newer, then also enable Single Sign-on for NetScaler Gateway.
    3. In a user-level GPO that applies to the VDA, add the StoreFront FQDN to the Local Intranet zone. Make sure it is not in the Trusted Sites zone, or enable Automatic logon with current user name and password for the Trusted Sites zone.
    4. Make sure ssonsvr.exe is running after you login to the VDA. If not, troubleshoot it.
  8. When configuring Citrix Profile Management, make sure !ctx_startmenu! is not excluded from roaming.
  9. In Citrix Studio, configure a Delivery Group with delivery type = Desktop and Applications. Assign users to the delivery group, and the individual published applications (if visibility is limited).
    1. In Citrix Studio, edit each published application, and on the Delivery tab, specify a category. This will become the Start Menu folder name.
    2. If Workspace app Self Service Mode (GUI) is enabled, in Studio, edit each application, and add KEYWORDS:Auto and/or KEYWORDS:Mandatory to the published application description. This forces the applications to be subscribed/favorited. Only subscribed (or Favorite) apps are displayed in the Start Menu and Desktop. Unless you disable Workspace app’s SelfService interface as described earlier.
    3. Another option is to go to the StoreFront Console, click Stores on the left, and on the right, click Configure Store Settings, and click Disable User Subscriptions. This causes all apps to appear on the Start Menu and/or Desktop depending on Workspace app configuration.
  10. Create a group policy that applies to VDAs, and configure the group policy to define the Store URL for Workspace app similar to https://citrix.corp.com/Citrix/Store/discovery. Replace the FQDN with your load balanced StoreFront FQDN. Also replace the path to the store with your store path. Make sure there is /discovery on the end. By default, Workspace app and Receiver only support https.
    1. Your StoreFront store probably delivers both application and desktop icons. If you want to filter out the desktop icons, then create a new StoreFront store, and configure the Workspace app on the VDA to connect to the new Store.
    2. In StoreFront Console, click the store for VDAs, and click Configure Store Settings. On the Advanced Settings page, in the Filter resources by type row, choose Citrix.MPS.Desktop.
  11. For vPrefer in Workspace app, VDA 7.17 (or newer), and StoreFront 3.14 (or newer), edit a GPO that applies to the VDAs.
    1. Go to Computer Configuration | Policies | Administrative Templates | Citrix Components | Citrix Workspace (or Receiver) | SelfService.
    2. Edit the setting vPrefer. This setting is only in Workspace app ADMX templates from Workspace app.
    3. Set it to Allow all apps. Source = 7.17 vPrefer – not working with 32Bit Apps at Citrix Discussions.
  12. On your Delivery Controller, in PowerShell, run set-brokersite -TrustRequestsSentToTheXmlServicePort $true
    • This is required for Pass-through Authentication from Workspace app.
  13. Configure your client devices to connect to the published desktop.
    1. When users connect to the published desktop, Workspace app will auto-launch and hopefully auto-login.
    2. If Workspace app Self-Service Mode is disabled, all published applications should automatically appear in the Start Menu and Desktop.
    3. If Workspace app Self-Service Mode is enabled, then only applications with KEYWORDS:Auto and/or KEYWORDS:Mandatory in the published application description will be displayed. Users can open the systray icon to subscribe to more applications.
    4. Users can copy icons from the Start Menu to the desktop. Make sure the user Copies the icon and doesn’t Move it.
    5. Users can then launch applications directly from the Start Menu, from the Desktop, or from the Workspace app (if the Self-Service interface is enabled).
    6. If Workspace app 4.11 (or newer), VDA 7.17 (or newer), and StoreFront 3.14 (or newer), then vPrefer is enabled by default. When launching an app icon that came from Workspace app, Workspace app checks the local VDA machine to see if the application can be launched on the local VDA instead of by creating a new Citrix double-hop session.
    7. If the application is installed locally on the VDA then the local application shortcut should launch quickly. If the application is on a different delivery group then a second (double-hop) Citrix HDX/ICA connection will be established.
    8. If the user deletes Workspace app shortcuts from the Start Menu, you can get them back by going to the systray icon and refreshing the applications. Or sometimes you have to reset Workspace app.

If you are running components older than Receiver 4.11, VDA 7.17, and StoreFront 3.14, then you’ll need to configure the prefer keyword to get Receiver delivered icons to launch on the local VDA instead of in a new double-hop Citrix connection.

  1. Enable the Group Policy setting Remove common program groups from Start Menu and apply it to non-administrators.
    1. For applications that are installed on the same VDA that is publishing the desktop, configure Group Policy Preferences to recreate the application shortcuts based on Active Directory group membership. Applications on other delivery groups are handled by Receiver.
    2. Or use the prefer keyword to copy shortcuts from the PreferTemplateDirectory.
  2. On the VDA, configure the following Receiver Registry keys (or corresponding settings in the receiver.admx GPO template):
    • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle\PreferTemplateDirectory = a UNC path or local path containing shortcuts to be copied by the prefer keyword. This can point to C:\ProgramData\Microsoft\Windows\Start Menu.
  3. In Citrix Studio, configure a Delivery Group with delivery type = Desktop and Applications. Assign users to the Delivery Group and the applications (if visibility is limited).
    1. In Studio, edit each application and change KEYWORDS:Prefer to KEYWORDS:prefer. Notice the lower case p. It doesn’t work with uppercase P.
      • With the prefer keyword, if you publish an application that is also created using Group Policy Preferences, the Group Policy Preferences icon will take precedence. This is good. Otherwise the Receiver published application icon would result in a new Citrix double-hop session.
      • See Ralph Jansen Citrix Receiver 4.1 Prefer keyword examples
    2. If using the prefer keyword with the PreferTemplateDirectory, enter it as KEYWORDS:prefer=shortcutname where shortcutname is the name of the shortcut that is copied from the Template directory.
  4. Configure your client devices to connect to the published desktop.
    1. When users connect to the published desktop, Group Policy Preferences will create shortcuts to local applications.
    2. Receiver will auto-launch and hopefully auto-login.
    3. If Receiver Self-Service Mode is disabled, all published applications should automatically appear in the Start Menu and Desktop.
    4. If Receiver Self-Service Mode is enabled then only applications with KEYWORDS:Auto and/or KEYWORDS:Mandatory in the published application description will be displayed. Users can open the systray icon to subscribe to more applications.
    5. For published applications with KEYWORDS:prefer=shortcutname, Receiver should copy icons from the template directory to the Start Menu and/or Desktop. See below for considerations.
    6. Users can copy icons from the Start Menu to the desktop. Make sure the user Copies the icon and doesn’t Move it.
    7. Users can then launch applications directly from the Start Menu, from the Desktop, or from the Receiver (if Self-Service interface is enabled).
    8. If a local shortcut (e.g. Group Policy Preferences shortcut, or copied from template directory) matches a published application with KEYWORDS:prefer then the local shortcut will override the published application icon.
    9. If the application is installed locally on the VDA then the local application shortcut should launch quickly. If the application is on a different delivery group then a second (double-hop) Citrix HDX/ICA connection will be established.
    10. If the user deletes Receiver shortcuts from the Start Menu, you can get them back by going to the systray icon and refreshing the applications. Or sometimes you have to reset Receiver.

Notes regarding Prefer Template Directory

  • Prefer Template Directory can point to C:\ProgramData\Microsoft\Windows\Start Menu, which is the All Users Start Menu.
  • The shortcuts copied from the Prefer Template Directory are renamed to match the published app name.
  • For prefer local apps, any command line parameters specified in the published app are ignored. If you need these command line parameters, add them to the shortcut in the Prefer Template Directory.
  • If you have multiple published apps pointing to the same prefer local shortcut, then only one copy will be made, and it will have the name of only one of the published apps. To workaround this, in the Prefer Template Directory, create separate shortcuts for each published app, and adjust the published app prefer keyword accordingly.
  • Jan Hendrik Meier Automatic Shortcut generation for local installed applications in a Citrix XenDesktop / XenApp 7.x environment has a script that can create shortcuts based on the published apps with prefer keyword. These shortcuts can then be copied to your Prefer Template Directory.

How to Script/Automate Workspace app and Receiver Self-Service

From Citrix Knowledgebase article Driving the Citrix Receiver Self-Service Plug-in Programmatically: by default, Workspace app Self-Service (SSP) activities are driven by user interaction. However, SSP exposes sufficient information for its activities to be scripted.

When SSP builds a shortcut, it builds it to a small stub application in a file %appdata%\Citrix\SelfService\app-name-with-spaces-removed.exe for each resource. These files allow SSP to create a fake ‘install’ record for Add/Remove Software. Running these .exe files causes the application to launch. Note: Workspace app and Receiver 4.3.100 and newer don’t create stubs by default. To enable, set HKLM\Software\Wow6432Node\Citrix\Dazzle\AlwaysUseStubs (REG_SZ) = true.

If you want to drive SSP directly for launch instead of through an .exe stub, look at the keys under HKCU\Software\Microsoft\Windows\CurrentVersion\Uninstall. There will be keys in there named farm-name@@server-farm-name.app-friendly-name. In these keys you’ll find a LaunchString value that shows the relevant parameters. These parameters are user-independent and can therefore be cloned from a reference user to a general case. You can copy and reuse these parameters without interpretation.

Running the command selfservice.exe –init –ipoll –exit starts SSP, performs a refresh (interactive poll) from the current provider, and forces a clean exit.

Additional command line parameters are detailed at Driving the Citrix Receiver Self-Service Plug-in Programmatically.

 

Citrix Workspace app come with a .dll file that implements the Citrix Common Connection Manager SDK. You can use the CCM SDK to do the following:

  • Launch Sessions
  • Disconnect Sessions
  • Logoff Sessions
  • Get Session Information

Citrix was kind enough to develop a PowerShell module that calls functions from the .dll. Get the CCMPowershellModule from Github. The PowerShell module contains functions like the following:

  • CCMTerminateApplication
  • CCMLaunchApplication
  • CCMGetActiveSessionCount
  • CCMDisconnectAllSessions

Launcher Scripts

Ryan C Butler Storefront ICA file creator at Github. See Create an ICA File from Storefront using PowerShell or JavaScript for more info.

Stan Czerno – Powershell Script to launch one or more Published Applications from Citrix Storefront 2.x through 3.11: the script launches a browser, connects to StoreFront (or NetScaler Gateway), logs in, and launches an icon. This is a very well-written script that uses a .dll file from Citrix Workspace app to display session information.

Citrix Solutions Lab StoreFront Launcher Script at Github. It attempts to closely resemble what an actual user would do by:

  1. Opening Internet Explorer.
  2. Navigating directly to the Receiver for Web site or NetScaler Gateway portal.
  3. Completing the fields.
  4. Logging in.
  5. Clicking on the resource.
  6. Logging off the StoreFront site.

David Ott StoreFront App/Desktop Launch Testing Script uses Internet Explorer to login to StoreFront and launch a resource. Sends email with the result. Uses wficalib.dll to get session information.

Microsoft Teams

Citrix and Microsoft jointly support the delivery of Microsoft Teams from Citrix Virtual Apps and Desktops using optimization for Microsoft Teams. The Teams optimization components are built into VDA and Workspace app. There is no need to install anything separately. The feature is based on Browser Content Redirection so don’t exclude that feature when installing the VDA.

Microsoft Teams optimization/offloading requires the following:

  • Newest version of Microsoft Teams machine-wide installation (ALLUSER=1)
  • Newest version of Citrix VDA
  • Newest version of Citrix Workspace app.

Feature matrix and version support at Citrix Docs shows the required versions of Teams, Citrix VDA, and Citrix Workspace app for various Teams features.

See Citrix Docs Optimization for Microsoft Teams.

Skype for Business

Citrix has a HDX RealTime Optimization Pack for Workspace app that enables offloading of Skype for Business media protocols to the client device. Here are the available versions:

The HDX RealTime Optimization Pack comes in two pieces: the Connector (on the VDA), and the Media Engine (on the Workspace app machine). Usually both pieces must be the same version, but versions 2.3 and higher now allow version mixing.

24-page Citrix PDF Delivering Microsoft Skype for Business to XenApp and XenDesktop Users.

For Skype for Business Location Based Routing, you’ll need the following: (Source = Citrix Derek Thorslund at Location based routing at Citrix Discussions)

  • Microsoft added support for Location Based Routing (LBR) with the virtualized Skype for Business 2016 client (and HDX RTOP 2.1 and above) in the Click-to-Run (C2R) download quite a long time ago, but it hasn’t yet been introduced in the MSI package.
  • It requires setting IsLBRInVDIEnabled on the Skype for Business Server to True:
    $x = New-CsClientPolicyEntry -Name "IsLBRInVDIEnabled" -Value "true"
    Set-CsClientPolicy -Identity "<ClientPolicyName>” -PolicyEntry @{Add=$x}

When offloading voice and video to Workspace app machines, don’t forget to configure QoS on the client machines. See Citrix Blog Post Implementing the Citrix HDX RealTime Optimization Pack: Don’t Forget About QoS/DSCP.

Citrix CTX222459 RealTime Optimization Pack Capability Checker: It will list out endpoint hardware/software information which will be used to process audio and video. The tool is independent of RealTime Optimization Pack version and runs any Windows machine.

Citrix CTX214237 LOPper – Lync Optimization Pack Log Parser: parses log files generated by Citrix HDX RealTime Optimization Pack (HROP) when an audio/video call is made using Lync 2013/Skype for Business (SfB) and shows relevant information in a UI.

Troubleshooting – Citrix QuickLaunch

Citrix CTX219718 QuickLaunch Tool (Testing Application and Desktop Launch) lets you launch Citrix sessions directly from a Controller without needing StoreFront.

You enter a Controller address, credentials, and then it shows you the published resources. You can pick a resource, edit properties on the other tabs, and then Connect. This allows you to easily try different connection properties.

If you run into problems launching a session, use Sysinternals DebugView while running CQL in Debug mode (/debug switch).

Troubleshooting – Workspace app Logging

In Workspace app 2309 and newer, if you right-click the Workspace app icon in the system tray, there’s a Troubleshooting menu with a Collect Logs option.

You can also access Log Collection from Advanced Preferences.

There are a couple methods of logging Workspace app for Windows operations. One method is CTX141751 Citrix Receiver Diagnostics Tool – For Windows, which creates a CDF trace that can be parsed by CDFControl.

Another method is CTX132883 How to Enable Logging on Receiver for Windows Using Registry Entries. The logfiles in %USERPROFILE%\Appdata\Local\Citrix\ are human readable. And CTX206102 Enable SSON Logging Using Registry Key.

Instead of creating the registry keys manually, you can use the following .reg file provided by Wolfgang Thürr:

Windows Registry Editor Version 5.00

Troubleshooting – Duplicate Stores

Stores are sometimes duplicated in Workspace app, especially if you are running Workspace app inside a VDA. (h/t Dan High)

StoreFront URLs can be defined in several places:

  1. In Studio, go to Configuration > StoreFront and delete all URLs configured here.
  2. Look in GPOs for Computer Configuration > Administrative Templates > Policies > Citrix Components > Citrix Workspace > StoreFront > NetScaler Gateway URL/StoreFront Accounts List. Remove any URLs configured here.
  3. In the client-side registry, at HKLM\Software\Wow6432Node\Citrix\Dazzle\Sites, you might see store addresses that were specified during a command line installation of Workspace app.
  4. When Citrix Workspace app switches between StoreFront servers in multiple datacenters, it’s possible for each datacenter to be treated as a separate Workspace app site. This can be prevented by doing the following. From Juan Zevallos at Citrix Discussions:
    1. Match the Base URL in all datacenters.
    2. Match the SRID in all datacenters – The SRID can be safely edited in the C:\inetpub\wwwroot\Citrix\Roaming\web.config. Make sure to propagate changes to other servers in the group.
    3. Match the Delivery Controller names under “Manage Delivery Controllers” – The XML brokers can be different, but the actual name of the Delivery Controller/Farm must be identical.

If you are running Workspace app on a VDA, once you’ve removed the configured URLs shown above, do the following to clean up the VDAs:

  1. On the VDA, HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Citrix – Delete the number folders representing policy entries.
  2. On session host VDAs, HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Terminal Server\Install\Software\Citrix – Remove the entries for storefront in the following folders.
    1. Under \receiver\ctxaccount delete all entries.
    2. Under \SR\Store delete the entries.
  3. On the VDA, C:\ProgramData\CitrixCseCache – Delete all files
  4. On the VDA, C:\ProgramData\Citrix\GroupPolicy – Delete all folders and files.
  5. Run gpupdate and logoff.
  6. In the user’s registry, HKEY_CURRENT_USER or the profile registry hive. Possible profile reset.
    1. Under Software\Citrix\Dazzle\Sites – Delete all entries.
    2. Under Software\Citrix\Receiver\ctxaccount – delete all entries.
    3. Under Software\Citrix\SR\Store – delete the entries.
  7. Verify no cached profile folders for user on server.

  3. Check the box next to Pass-through from NetScaler Gateway and click OK.
  4. If you can’t resolve the NetScaler Gateway FQDN from the StoreFront server, edit the C:\Windows\System32\drivers\etc\hosts file and add an entry for the NetScaler Gateway FQDN.

    After configuring the HOSTS file, on the StoreFront server, open a browser and navigate to the DNS name. Make sure the Gateway vServer logon page appears.
  5. In the StoreFront Console, right-click NetScaler Gateway and click Add NetScaler Gateway Appliance.
  6. In the Gateway Settings page, enter a display name. This name appears in Citrix Receiver to make it descriptive. If you have multiple sites, include a geographical name.
  7. Enter the NetScaler Gateway Public URL. The NetScaler Gateway FQDN must be different than the FQDN used for load balancing of StoreFront (unless you are configuring single FQDN). This can be a GSLB-enabled DNS name.
  8. A Subnet IP address is not needed for NetScaler Gateway 10 and newer. However, if the NetScaler Gateway URL is GSLB-enabled then you’ll need to enter the VIP of the NetScaler Gateway Virtual Server so StoreFront can differentiate one NetScaler Gateway from another.
  9. Enter the Callback URL.
    1. In StoreFront 2.6 and newer, the Callback URL is optional. However, SmartAccess requires the Callback URL to be configured.
    2. The callback URL must resolve to any NetScaler Gateway VIP on the same appliance that authenticated the user. For multi-datacenter, edit the HOSTS file on the StoreFront server so it resolves to NetScaler appliances in the same datacenter.
    3. The Callback URL must have a trusted and valid (matches the FQDN) certificate.
    4. The Callback URL must not have client certificates set to Mandatory.
  10. If you have two-factor authentication (LDAP and RADIUS), change the Logon type to Domain and security token. Otherwise leave it set to Domain only.
  11. Click Next.
  12. In the Secure Ticket Authority page, click Add.
  13. Add both of your Controllers. Use http:// or https:// depending on the certificates installed on the Controllers. You can also enter a Load Balancing VIP here. However, you cannot use a Load Balancing VIP when configuring Secure Ticket Authorities on your NetScaler Gateway Virtual Server.
  14. Click Create when done.
  15. Then click Finish.
  16. Click Stores on the left. On the right, click Enable Remote Access.
  17. Select No VPN tunnel.
  18. Check the box next to the NetScaler Gateway object you just created and then click OK.
  19. Then in the StoreFront console, right-click Server Group and click Propagate Changes.

Single FQDN

Docs.citrix.com – Create a single Fully Qualified Domain Name (FQDN) to access a store internally and externally

Traditionally Receiver required separate FQDNs for StoreFront Load Balancing (internal) and NetScaler Gateway (external). Recently Citrix made some code changes to accept a single FQDN for both. This assumes that external users resolve the single FQDN to NetScaler Gateway and internal users resolve the same FQDN to StoreFront Load Balancing.

Single FQDN is fairly new and thus has the following requirements:

  • Receiver for Windows 4.2 or newer
  • Receiver for Mac 11.9 or newer
  • StoreFront 2.6 or newer
  • Split DNS – different DNS resolution for internal vs external
  • NetScaler 10.1 or newer

This section assumes NetScaler Gateway is in ICA Proxy mode. Different instructions are needed for when ICA Proxy is off. See docs.citrix.com for more information.

If you don’t care about email-based discovery then the configuration of Single FQDN is fairly simple. Sample DNS names are used below. Make sure the certificates match the DNS names.

  1. Internal DNS name = the Single FQDN (e.g. storefront.corp.com). Resolves to internal Load Balancing VIP for StoreFront. Set the StoreFront Base URL to this address.
  2. External DNS name = the Single FQDN (e.g. storefront.corp.com). Resolves to public IP, which is NAT’d to NetScaler Gateway VIP on DMZ NetScaler. Set the NetScaler Gateway object in StoreFront to this FQDN.
  3. Auth Callback = any internal DNS name (e.g. storefrontcb.corp.com) that resolves to a NetScaler Gateway VIP on the same DMZ NetScaler appliance that authenticated the user.

    • Auth callback is optional if you don’t need SmartAccess features.
    • The callback DNS name must be different than the Single FQDN.
    • Your external NetScaler Gateway certificate could match both the Single FQDN and the Callback FQDN. Or you can create separate NetScaler Gateway Virtual Servers on the same appliance with separate certificates that match these FQDNs.
  4. Internal Beacon = any internal website URL that is not externally accessible. You can’t use the Single FQDN as the Internal Beacon. Ideally, the Internal Beacon should be a new DNS name that resolves to the StoreFront Load Balancing VIP. However, this requires the StoreFront Load Balancing Virtual Server to have a certificate that matches both the Single FQDN and the Internal Beacon. See CTX218708 How to Configure Internal Beacon for Single FQDN on StoreFront.  💡

    • If are using Receiver for iOS internally then be aware that Receiver for iOS handles the Internal Beacon differently than Receiver for Windows. Receiver for iOS will append /Citrix/Store/discovery to the Internal Beacon and thus it only works if the Internal Beacon DNS name resolves to the StoreFront server. Since you can’t use the StoreFront Base URL as the Internal Beacon you’ll need a different DNS name that resolves to the StoreFront servers and matches the StoreFront certificate. Note: if you are not allowing internal iOS devices then this isn’t needed.
  5. Make sure the DMZ NetScaler resolves the Single FQDN to the internal StoreFront Load Balancing VIP. You typically add internal DNS servers to the NetScaler. Or you can create a local address record for the Single FQDN.
  6. In the NetScaler Gateway Session Profile, set the Web Interface Address and the Account Services Address to the Single FQDN.

If you need email-based discovery then here’s an example configuration for ICA Proxy NetScaler Gateway:

  • External DNS:
    • Storefront.corp.com resolves to public IP, which is NAT’d to NetScaler Gateway VIP on DMZ NetScaler.
    • If email-based discovery, SRV record for _citrixreceiver._tcp.email.suffix points to StoreFront.corp.com.
  • External publicly-signed certificate for NetScaler Gateway:
    • One option is wildcard for *.corp.com. Assumes email suffix is also corp.com.
    • Another option is the following Subject Alternative Names:
      • Storefront.corp.com
      • StorefrontCB.corp.com – for callback URL. Only accessed from internal.
        • Or you can create a separate Gateway vServer for callback with a separate certificate.
      • If email-based discovery, discoverReceiver.email.suffix
  • Internal DNS:
    • Storefront.corp.com resolves to Load Balancing VIP for StoreFront
    • StoreFrontCB.corp.com – resolves to NetScaler Gateway VIP on DMZ NetScaler. For authentication callback.
    • For the internal beacon, FQDN of any internal web server. Make sure this name is not resolvable externally.
    • If email-based discovery, SRV record for _citrixreceiver._tcp.email.suffix points to StoreFront.corp.com.
  • Internal certificate for StoreFront Load Balancing: publicly-signed recommended, especially for mobile devices and thin clients. Also can use the external certificate.
    • One option is wildcard for *.corp.com. Assumes email suffix is also corp.com.
    • Another option is the following Subject Alternative Names:
      • Storefront.corp.com
      • If email-based discovery, discoverReceiver.email.suffix

StoreFront Configuration:

  • Base URL = https://storefront.corp.com
  • Internal beacon = FQDN of internal web server. Make sure it’s not resolvable externally.
  • Gateway object:
    • Gateway URL = https://storefront.corp.com
    • Callback URL = https://storefrontcb.corp.com

Multiple Datacenters / Farms

If you have StoreFront (and NetScaler Gateway) in multiple datacenters, GSLB is typically used for the initial user connection but GSLB doesn’t provide much control over which datacenter a user initially reaches. So the ultimate datacenter routing logic must be performed by StoreFront. Once the user is connected to StoreFront in any datacenter, StoreFront looks up the user’s Active Directory group membership and gives the user icons from multiple farms in multiple datacenters and can aggregate identical icons based on farm priority order. When the user clicks on one of the icons, Optimal Gateway directs the ICA connection through the NetScaler Gateway that is closest to the destination VDA. Optimal Gateway requires datacenter-specific DNS names for NetScaler Gateway.

Docs.citrix.com Set up highly available multi-site store configurations explains configuring XML files on StoreFront to aggregate identical icons from multiple farms/sites. Identical Icons are aggregated in farm priority order or load balanced across multiple farms. To specify a user’s “home” datacenter, configure different farm priority orders for different Active Directory user groups.

Shaun Ritchie Citrix StoreFront High Availability and Aggregation – A dual site Active Active design has a sample multi-site configuration using XML Notepad and explains how to use the Primary and Secondary keywords to override farm priority order.

Citrix Blogs StoreFront Multi-Site Settings: Some Examples has example XML configurations for various multi-datacenter Load Balancing and failover scenarios.

When Citrix Receiver switches between StoreFront servers in multiple datacenters, it’s possible for each datacenter to be treated as a separate Receiver site. This can be prevented by doing the following. From Juan Zevallos at Citrix Discussions: To have multiple StoreFront deployments across a GSLB deployment, here are the StoreFront requirements:

  • Match the SRID – in StoreFront, if you use the same BaseURL in the 2 separate installations, then the SRID should end up being identical. If the BaseURL is changed after the initial setup, the SRID doesn’t change. The SRID can be safely edited in the \inetpub\wwwroot\Citrix\Roaming\web.config file. It will be replicated into the discovery servicerecord entry in the Store web.config which can be edited as well or refreshed from the admin console by going into Remote Access setup for the store and hitting OK. Make sure to propagate changes to other servers in the group.
  • Match the BaseURL
  • Match the Delivery Controller names under “Manage Delivery Controllers” – The XML brokers can be different, but the actual name of the Delivery Controller/Farm must be identical. Here’s the exact setting I’m referring to: https://citrix.sharefile.com/d/sa562ba140be4462b

If you are running XenApp / XenDesktop in multiple datacenters, you must design roaming profiles and home directories correctly.

Optimal Gateway

The Optimal Gateway feature lets you override the NetScaler Gateway used for ICA connections. Here are some scenarios where this would be useful:

  • The NetScaler Gateway Virtual Server requires user certificates. If ICA traffic goes through this Virtual Server then each application launch will result in a certificate prompt. Use Optimal Gateway to force ICA connections through a different NetScaler Gateway Virtual Server that doesn’t have certificate authentication enabled. Note: Callback URL also cannot use a NetScaler Gateway Virtual Server where client certificates are set to Mandatory.
  • Multi-site Load Balancing. If the icon selected by the user is published from XenApp/XenDesktop in Datacenter A, then you probably want the ICA connection to go through a NetScaler Gateway Virtual Server in Datacenter A. This requires separate NetScaler Gateway DNS names for each datacenter. Also, Optimal Gateway is applied at the farm/site level so if you are stretching a farm across datacenters then Optimal Gateway won’t help you.
  • NetScaler Gateway for internal connections (AppFlow). If you want to force internal users to go through NetScaler Gateway so AppFlow data can be sent to Citrix Insight Center then you can do that using Optimal Gateway even if the user originally connected directly to the StoreFront server. See How to Force Connections through NetScaler Gateway Using Optimal Gateways Feature of StoreFront for more information.

Optimal Gateway is configured by editing the StoreFront Store’s web.config file. See Docs.citrix.com: To configure optimal NetScaler Gateway routing for a store. For an example configuration see Docs.citrix.com: Examples of highly available multi-site store configurations.

Optimal Gateway works great if you have separate XenDesktop sites/farms in each datacenter. However, for those of you with a central XenDesktop site running globally dispersed VDAs and a NetScaler Gateway in each location, or a single globally distributed XenApp farm (which I know an awful lot of you still have), see the Citrix blog post – How to direct remote XenApp/XenDesktop users based on active directory group membership:

    1. On a Load Balancing NetScaler, create multiple StoreFront load balancers. Each has a unique Net Profile with a unique SNIP.
    2. On StoreFront, create multiple Gateway objects, each with a SNIP that matches the Net Profiles created on the load balancer. Each Gateway object has a datacenter-specific Gateway FQDN.
    3. On each NetScaler Gateway:
      1. Configuration LDAP group extraction.
      2. Create a session policy for each datacenter pointing to the one of the StoreFront Load Balancers.
      3. Create AAA groups and bind the session policies.

Gateway in Closest Datacenter

Citrix Blog post ‘Accurately’ Direct XenApp/XenDesktop Users to a Correct Location Based Datacenter:

  • An unsupported extension to StoreFront
  • Read’s the client’s IP and looks it up in a location database (GeoLite2) to determine the user’s closest datacenter
  • Adjusts the Gateway FQDN in the rendered .ica file to direct users to the closest datacenter.
  • Requires datacenter-specific or region-specific Gateway DNS names.
  • Every NetScaler Gateway should know about every potential Secure Ticket Authority server.

Multiple Gateways to One StoreFront

If you have multiple NetScaler Gateways connecting to one StoreFront Server Group, and if each of the NetScaler Gateways uses the same DNS name (GSLB), then you will need some other method of distinguishing one appliance from the other so the callback goes to the correct appliance.

  • In the StoreFront console, create multiple NetScaler Gateway appliances, one for each datacenter. Give each of them unique names.
  • Enter the same NetScaler Gateway URL in all of the gateway appliances. Since all of the appliances use the same DNS name, you cannot use the DNS name to distinguish them.
  • Each appliance has a different NetScaler Gateway VIP. This VIP can be entered in the Subnet IP field. StoreFront will use this VIP to distinguish one appliance from another. The field label is SNIP but we actually need to enter a VIP.
  • The callback URL must be unique for each Gateway appliance. The callback URL must resolve to a NetScaler Gateway VIP on the same appliance that authenticated the user. Create new datacenter-specific DNS names. For example: gateway-prod.corp.com and gateway-dr.corp.com.
  • The datacenter-specific DNS name must match the certificate on the NetScaler Gateway Virtual Server. Here are some options to handle the certificate requirement:
    • On the main NetScaler Gateway Virtual Server, assign a wildcard certificate that matches both the GSLB name and the datacenter-specific name.
    • On the main NetScaler Gateway Virtual Server, assign an SSL certificate with Subject Alternative Names for both the GSLB name and the datacenter-specific name.
    • Create an additional NetScaler Gateway Virtual Server on the appliance. Bind a certificate that matches the datacenter-specific name.
  • Configure name resolution for the datacenter-specific NetScaler Gateway DNS names. Either edit the HOSTS file on the StoreFront servers or add DNS records to your DNS servers.
  • When enabling Remote Access on the store, select both Gateway appliances. Select one as the default appliance.

Session Policies for StoreFront – NetScaler Gateway 10.5

Last Modified: Nov 6, 2020 @ 7:06 am

Navigation

This page details creation of session profiles and policies for NetScaler Gateway 10.5 where ICA Only (formerly known as Basic Mode) is checked.

Partly based on Citrix Knowledgebase Article – How to Configure NetScaler Gateway with StoreFront

Session Profiles/Policies CLI Commands

The CLI commands are shown below:

add vpn sessionAction "Receiver Self-Service" -transparentInterception OFF -defaultAuthorizationAction ALLOW -SSO ON -icaProxy ON -wihome "https://storefront.corp.com" -ntDomain Corp -clientlessVpnMode OFF -storefronturl "https://storefront.corp.com"

add vpn sessionAction "Receiver for Web" -transparentInterception OFF -defaultAuthorizationAction ALLOW -SSO ON -icaProxy ON -wihome "https://storefront.corp.com/Citrix/StoreWeb" -ntDomain Corp -clientlessVpnMode OFF

add vpn sessionPolicy "Receiver Self-Service" "REQ.HTTP.HEADER User-Agent CONTAINS CitrixReceiver" "Receiver Self-Service"

add vpn sessionPolicy "Receiver for Web" "REQ.HTTP.HEADER User-Agent NOTCONTAINS CitrixReceiver" "Receiver for Web"

Session Profiles

Or use the GUI to create the policies/profiles:

  1. On the left, expand NetScaler Gateway, expand Policies, and click Session.
  2. On the right, switch to the Session Profiles tab, and click Add.
  3. Name the first one ReceiverSelfService or similar. This is for Receiver Self-Service (not in a web browser).
  4. Switch to the Client Experience tab.
  5. Check the Override Global box next to Clientless Access, and set it to Allow. Scroll down.
  6. Check the Override Global box next to Plug-in Type and set it to Java.
  7. Check the Override Global box next to Single Sign-on to Web Applications and enable it. Scroll up.
  8. If you need two-factor authentication, the session policy for Receiver Self-Service needs to be adjusted to indicate which authentication field contains the Active Directory password. On the Client Experience tab is Credential Index. This needs to be changed to SECONDARY. Leave the session policy for Web Browsers set to PRIMARY.
  9. On the Security tab, check the Override Global box next to Default Authorization Action and set it to Allow.
  10. On the Published Applications tab, check the Override Global box next to ICA Proxy and set it to ON.
  11. Check the Override Global box next to Web Interface Address, and enter the load balanced URL to the StoreFront servers. You can use an IP address. Don’t add any path to the end of the URL.
  12. If you only have one domain, then check the Override Global box next to Single Sign-on Domain and enter the name of your Active Directory domain. StoreFront needs to accept this domain name (Configure Trusted Domains).
  13. If you have multiple domains, then leave Single Sign-on Domain field blank, and ensure the LDAP authentication servers have userPrincipalName in the SSO Name Attribute field.
  14. For Account Services Address, enter the Base URL for StoreFront. NetScaler needs to be able to resolve this DNS name.
  15. Click Create.
  16. Highlight the existing session profile, and click Add. This copies the settings from the existing profile into the new one.
  17. Change the name of the second Session Profile to ReceiverForWeb or similar.
  18. On the Client Experience tab, Clientless Access should be set to Allow. Scroll down.
  19. Plug-in Type should still be set to Java.
  20. Single Sign-on to Web Applications should be enabled.
  21. If you need two-factor authentication, the session policy for Receiver for Web needs Credential Index set to PRIMARY. Only the Receiver Self-Service policy needs SECONDARY as detailed earlier.
  22. On the Security tab, the Default Authorization Action should still be Allow.
  23. On the Published Applications page, for the Web Interface Address field, add the path to your Receiver for Web site (e.g. /Citrix/StoreWeb).
  24. Everything else should be the same. If you only have one domain, then check the Override Global box next to Single Sign-on Domain and enter the NetBIOS name of your Active Directory domain. If you have multiple domains, then leave this field blank and ensure the LDAP authentication servers have userPrincipalName in the SSO Attribute field.
  25. Account Services Address is not needed in this profile but there’s no harm in leaving it.
  26. Click Create.

Session Policies

  1. On the right, switch to the Session Policies tab, and click Add.
  2. Name the Policy ReceiverSelfService or similar.
  3. Change the Request Profile to ReceiverSelfService.
  4. In the Expression box, either type the following, or use the Expression Editor link to build the following expression:
    REQ.HTTP.HEADER User-Agent CONTAINS CitrixReceiver

  5. Then click Create.
  6. Add another policy, and name it ReceiverForWeb or similar.
  7. Change the Action to ReceiverForWeb.
  8. In the Expression box, either type in the following, or use the Expression Editor. It’s the same as the previous expression, except it’s NOTCONTAINS instead of CONTAINS.
    REQ.HTTP.HEADER User-Agent NOTCONTAINS CitrixReceiver
  9. Click Create.

    bind ssl vserver lbvip-StoreFront-SSL -eccCurveName ALL
    
    bind lb vserver lbvip-StoreFront-SSL -policyName insert_STS_header -priority 100 -gotoPriorityExpression END -type RESPONSE
  28. Then click Done.

SSL Redirect – Down vServer Method

If you created an SSL Offload Virtual Server that only listens on SSL 443, users must enter https:// when navigating to the website. To make it easier for the users, create another load balancing Virtual Server on the same VIP that listens on HTTP 80 and then redirects the user’s browser to reconnect on SSL 443.

This procedure details the Down vServer method of performing an SSL redirect. An alternative is to use the Responder method.

  1. On the left, under Traffic Management > Load Balancing, click Virtual Servers.

  2. On the right, find the SSL Virtual Server you’ve already created, right-click it, and click Add. Doing it this way copies some of the data from the already created Virtual Server.
  3. Change the name to indicate that this new Virtual Server is an SSL Redirect.
  4. Change the Protocol to HTTP on Port 80.
  5. The IP Address should already be filled in. It must match the original SSL Virtual Server.
  6. Click OK.
