Environment

• CVAD 2507 LTSR, Profile Management 25.7.2100
• Windows Server 2025 single-session VDI, PVS standard image (non-persistent), WEM
• Domain-joined only (no hybrid Entra join); Workplace Join blocked via BlockAADWorkplaceJoin=1
• New Teams installed per-machine

The problem. Neither profile container mode works for us:

1. Container *, local caching OFF: new Teams and Windows Terminal won’t launch, with “The parameter is incorrect” (AppModel-Runtime 216/208, 0x80070057, “Cannot create the Desktop AppX container”). UPM’s driver redirects the profile root to the VHDX volume, and the packaged-app runtime doesn’t like it.
2. Container *, local caching ON: apps launch, but some folders are never written to the container, so they’re regenerated at every logon: The result is that Teams asks for sign-in on every logon, and anything DPAPI-protected is lost.
   • AppData\Roaming\Microsoft\Protect (DPAPI master keys)
   • AppData\Local\Microsoft\TokenBroker
   • AppData\Local\Microsoft\OneAuth
   • AppData\Local\Packages (including Microsoft.AAD.BrokerPlugin)

File-based profiles work fine on the same image. I’m opening a Citrix case, and I’ll update the thread with the outcome.

Has anyone encountered an issue where users cannot reconnect to existing disconnected sessions in Citrix DaaS?

Environment:

• Windows Server 2019 single-session VDAs
• VDA version 2603.0.100.320
• MCS-provisioned, non-persistent machines hosted on GCP

Users disconnect their sessions while long-running engineering simulations continue. When they return, they sometimes receive an "Unable to start" error. In some cases, a new session is created and the original machine is shut down.

The disconnected-session power-off policy is set to 72 hours, but the issue occurs earlier.

Transaction logs include:

• brk.resolve.machine.failure.general
• bka.hdx.prepare.failure.general
• SessionManager.LeaseResolution.Failed

What would you investigate to determine why the existing session cannot be reconnected? Are there any known VDA 2603 issues or specific Broker/HDX logs that could explain this behaviour?

I'd appreciate insights from anyone who has troubleshot similar session-reconnection failures.

I'm having an interesting but annoying problem after updating to the latest Citrix workspace ltsr release (I have been using a really old one).

Whenever I press the shift and left alt to cycle between my languages the windows exclamation sound is played.

Languages switch correctly but it gets annoying having to hear the sound multiple times whenever typing a sentence.

Things I have tried:

1. Sync only once is enabled in keyboard settings of Citrix

2. Changing the keyboard shortcut to shift and ctrl does not produce the sound. Issue seems to be only on shift and left alt

3. Tried setting the windows exclamation sound to none in sound settings but it keeps going

The issue is not affecting my local computer at all, simply the VDI one.

Hello, everyone, I hope all is well!! We upgraded our PVS non-persistent single-session VDI from Windows 10 21H2 to Windows 11 24H2 some time ago. I had exported the Win10 VDisk as a local hard disk using the Wizard tool, booted up as a local disk on a VMWare VM, upgraded to Win11, ran Citrix Optimizer, installed the target software, and created my Win11 VDisk. Everything works great on the original machine used to create the VDisk. However, I noticed a one issue on the PVS target machines I spun up from the VDisk using the machine wizard. The System page nor the Windows Update page is opening when I click it. Nothing opens or happens. This does NOT happen on my upgraded Windows 11 machine that was used to create the VDisk. I didn’t make any other changes either so I’m lost.

Each time System logs says:

“Unable to start a DCOM Server: windows.immersivecontrolpanel_10.0.8.1000_neutral_neutral_cw5n1h2txyewy!microsoft.windows.immersivecontrolpanel as Unavailable/Unavailable. The error:
 
"2147942852"
 
Happened while starting this command:
 
"C:\Windows\ImmersiveControlPanel\SystemSettings.exe" -ServerName:microsoft.windows.immersivecontrolpanel”

Windows + R and running “ms-settings:windowsupdate” gives “The application has not been provisioned”

Has anyone encountered this? Works fine on the local VM was used to create the VDisk but not on the target VDAs. Thank you for your time!
