Windows Server 2022 Remote Desktop - Black Screen

Simon Miles 1

We've recently installed a Server 2022 as a Remote Desktop Server.
We have a load of Mac users, some laptops, some desktops who connect using the Microsoft Remote Desktop app from the app store.
We are finding that when a user gets disconnected, whether its VPN drops out, or the Mac goes to sleep and closes the RDP connection, when that user tries to log back into their remote desktop session, they get a black screen.
If I try and connect to that session on the server, the black screen appears for me too. I also notice the network information bar shows 1 or 2 bars out of the 4.
To get the user back signed in, I have to manually close the Windows Logon User Interface service (I think thats what its called)
Some of these users are connecting on the local network over wireless and some are connected with an ethernet cable.
Really odd. Has anyone else seen this before?
Many thanks

Hi, I have added the specified keys into the Registry Editor and restarted the server. However, after logging in, the server continues to display “Preparing Windows” and does not proceed further. As a result, I am unable to access the server

Unfortunately, end users have started reporting the black screen again!

I had thought moving the licensing role to another server had fixed it, but that doesn't appear to be the case.

What is odd....Although licencing is clearly on a different server and the CALs have been moved successfully, the licensing role server doesn't appear to be issuing licenses to those who login to the remote desktop server.

It has only licenses 1 user (an admin) which I used to test it...

Any thoughts?

Many thanks

Same problem here. New 2022 RDS running as an VM on HyperV-host.

RDS winver -> 20348.1668
Does not matter if client is local or remote using VPN, nor if the client is running fully patched windows 10, or using HPE's thin client (runs linux of some sort).
Completely random....
Only way out is for me as admin to kill logonui.exe for the user with black screen and then logout the user.

Any ideas?
