Windows server 2019 - FREEZES

Question

Hi. When working on a terminal server, the client often freezes.

There are no errors in the logs. I read that UDP may be the problem. But turning it off is a bad decision.

Answer 1

Disabling UDP helped. Is there any fix without disabling UDP?

Answer 2

Hi，

You may try setting set the group policy "Use WDDM graphics display driver for Remote Desktop Connections" under "Computer Configuration->Policies->Windows Settings->Administrative Templates->Windows Components->Remote Desktop Services->Remote Desktop Session Host->Remote Session Enviroment" to Disabled.
This will force the use of XDDM graphics display drive.

Best Regards,
Ian Xue
