The latest round of Windows Update breaks admin shares, MMC tools, etc. between MCS provisioned machines.
The issue is due to duplicate Computer SIDs. Both MS and Citrix have pages/articles saying duplicate SIDs don't matter in domain environments, but they clearly didn't think about cloned machines when they made the recent cert/auth changes.
All that being said, the way to get unique SIDs is via Sysprep. Of course, Citrix says NO Sysprep for MCS.
Sorry, long question to ask, are you doing anything to work around Citrix's no sysprep guidance? Is this a non-issue for you?
Here is a link to a post I found:
Windows 11 VDI's created with Citrix MCS + KB5064081/KB5065426 : r/Citrix
