Remote Desktop no work after windows 11's update

Question

Good morning,

Since I upgraded my virtual machine to Windows 11, remote desktop with a VPN no longer works. Indeed, after entering my credentials, it shows me the attached error. To know that:

• Connecting from an Ethernet cable works.
• After a restart of the machine, the connection works for a few minutes with a VPN but then hangs.
• The connection works with Windows 10 clients but does not work with Windows 11 clients and the Remote Desktop application.

Also, I manage to access the other VMs on Windows 10 after this error, so the connection cannot come from the VPN.

Thank you in advance for your answer

Hello there,

If you started noticing that the Windows 11 Remote Desktop is not working after installing the 22H2 update, it is because the feature is trying to connect with UDP. The solution here is to disable UDP by creating a new registry value.

You will expand the folder that says HKEY_LOCAL_MACHINE, then expand the folder that says SOFTWARE, then expand Policies, then Microsoft, then Windows NT, then Terminal Services, then Client.

You will then select the Client folder so that its highlighted (it's blue on mine), and in the menu bar at the top, click EDIT, NEW, DWORD (32-bit) Value. The 32 and 64 bits have nothing to do with your computer being a 64bit or 32bit, by the way.

Then you will will see a new item pop up in the right side of the screen that says New Value #1. You will edit that to say fClientDisableUDP. Then you will right click on it, and select MODIFY, and in the box with the 0 in it, change that to 1.

Then reboot your computer and it should fix it.

Hope this resolves your Query !!

Answer 5

The problem still hasn't resolved itself and I'm going to need it resolved very soon. Also, since I migrated more than 2 weeks ago, I can't go back to Windows 10 anymore. Do you have a solution for me?
