Managing Citrix Client Selective Trust settings on AAD devices using Intune

-

Citrix Workspace app for Windows provides access to a user’s resources using Citrix Virtual Apps and Desktops. These resources include SaaS, web and legacy applications and desktops. Citrix Workspace app provides access from the desktop, start menu, Citrix Workspace user interface and web browsers.

Now in an Active Directory infrastructure, Citrix Workspace app can be centrally configured using Microsoft group policies. This requires that the administrative templates (the ADMX and ADML files) for Citrix Workspace app are copied to your Group Policy Central Store. Part of these setting include configuring Client Selective Trust registry keys which allows controlling the user permission prompts in a Citrix session related to access of resources on the device like local drives, webcams, microphones etc.

But how does one address this on devices that are Azure AD joined only? If you are managing devices using Intune, then one can using PS scripts to configure the necessary registry keys. At the time of writing this blog, following keys are available that can be configured.











It took me a while to research for the settings, therefore I decided to share the details on the setup through this post to help others save some time. I basically configured the settings myself and exported them to be used later in a script for configuration during Autopilot provisioning. Following is the script that I put together to configure some of the relevant settings.

3. Click Add
4. Provide a Name and hit next
5. Under Script settings, select the desired script.
6. Select No against Run this script using the logged on credentials option.
7. Select No against Enforce script signature check option.
8. Select Yes against Run script in 64 bit PowerShell Host option.
9. Assign the script to a device-based group.

How to force escrowing of BitLocker recovery keys using Intune

-
Image
Every now and then it so happens that BitLocker recovery keys do not escrow in AAD. The usual culprits are incorrect BitLocker policies and\or the device hardware configuration failing to meet the minimum requirements. The other scenario and something I recently experienced is when everything is setup right and still the recovery key doesn’t escrow in AAD. As I understand, this can happen if the escrow process got interrupted the first time due to network or local devices related issues and the process could not resume. To circumvent this issue, one can simply push a PowerShell script to the devices to force the escrow of the recovery keys to AAD. Here is a script to do so. try{ $BitlockerVol = Get-BitLockerVolume -MountPoint $env:SystemDrive         $KPID=""         foreach($KP in $BitlockerVol.KeyProtector){             if($KP.KeyProtectorType -eq "RecoveryPassword"){              ...

Prevent users from running certain programs or applications on Windows endpoints using Intune

  When it comes to blocking or preventing users from running an application on Windows devices, one normally uses App locker policy, Windows Defender Application Control and not so new but pretty useful method called Defender Vulnerability management within Microsoft 365 Defender Portal. A recent question on the Tech Community Microsoft forum prompted me to look for all possible alternatives. I started reminiscing over the legacy GPO policies and that is when I stumbled upon the policy  Don’t run specified Windows applications  located under User Administrative Templates - The policy setting does come with its own caveat - " This policy setting only prevents users from running programs that are started by the File Explorer process. It does not prevent users from running programs, such as Task Manager, which are started by the system process or by other processes. Also, if users have access to the command prompt (Cmd.exe), this policy setting does not prevent them from st...

Intune: Configure Printers for Non-Administrative Users

-
Image
Configuring printers for end users or giving them the ability to do it themselves is a normal requirement for organizations. Now if your users are Administrators, then the configuration can be straight forward, but in case of Non-Administrators there are additional steps required as Non-Administrators will not be able to add a driver in the driver store despite being able to install a printer. In this blog, I will cover the steps that I took to address this requirement using Intune. The setup involves 2 steps -  1. Setup registries. 2. Install the driver and configure the printer Setting up registries – The registries that need to be configured are actually part of a GPO setting – Allow non-administrators to install drivers for these device setup classes It can be found under: Computer Configuration -> Policies -> Administrative Templates -> System -> Driver Installation I used a Powershell script to set the values and wrapped it in a Win32 application. $P...
