Unable to remote into terminal server using the mstsc /admin

Question

Hi,

On Windows 11 we are unable to remote into our terminal server using the Mstsc /admin command.

If remoting into the terminal server without invoking admin rights it remotes just fine.

If using the /admin on a Windows 10 machine we can remote to the terminal server just fine as well.

It seems to be a problem with Windows 11. We even tried different admin user to remote into the terminalserver but the error is the same.

I understand that there was an patch fix for a similar issue a couple weeks ago. Before the patch fix the remote connection was stuck on "estimating connection quality".

Now with the new patch in place the error is showing attached.

Any help on this would be much appreciate it.
