Issues with Remote Desktop on Windows 11 after Update 22H2

Anonymous

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.

    Thank you ever so much for sharing the fix!

    Also a home user who accesses Remote Apps.

    Ever since I updated to Windows 11 22H2 it would get stuck on Configuring Remote Session and I could only close it via Task Manager. I had no clue on what to do especially since Remote Apps were working on my other devices.

    Thank you so much for that explanation! I am a home user, but I use RDP via a browser to connect to my company's database. I took the 22H2 update and that's where all the problems started. The company's I.T. department is unavailable on weekends generally. Your explanation saved the day!

    You need to right-click and create a new DWORD value called fClientDisableUDP and then change the actual value to 1. Restart the computer after you're done.
