Issues with Remote Desktop on Windows 11 after Update 22H2

All of our Remote Desktop Users using Windows 11 are having problems connecting to Remote Desktop after installing this update. It just hangs at connecting.

We have found that there is a bug in the Remote Desktop client so that it is only trying the UDP connection and not trying TCP connection. We only allow the port 443 connection through on our firewall.

The only workaround we have found is to make the following change on the Windows 11 computer.

Have to set this value to 1 in the registry for Windows 11 client to work outside the network

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client

KEY VALUE - fClientDisableUDP SET TO 1

Otherwise the Remote client just keeps trying to connect via UDP.

This issue did not start until the Windows 11 update was installed over the last couple days.

    Well I'm a home user and I have got the same problem - I work a casual job 2 days a week from home and cannot connect to the remote desktop after downloading the Windows 11 Update. How do I fix this?
