After the version update of Windows 11 to 22H2, Windows 11 uses the protocol UDP instead of TCP for Remote Desktop connections. Currently our load balancer does not forward the UDP packets, which prompts the message "The virtual computer is loading".
Our network department is currently checking whether it is possible to configure the load balancer for UDP. Until then a registry key must be adjusted under Windows 11.
To do this, press "Win + R" and enter "regedit". Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client
Search for the entry "fClientDisableUDP".
If it does not exist, create a new DWORD value named "fClientDisableUDP" and set the value (right click -> Change) to "1".
