Select RDP transport protocols

This policy setting allows you to specify which protocols can be used for Remote Desktop Protocol (RDP) access to this server.

If you enable this policy setting, you must specify if you would like RDP to use UDP.

You can select one of the following options: "Use both UDP and TCP", "Use only TCP" or "Use either UDP or TCP (default)"

If you select "Use either UDP or TCP" and the UDP connection is successful, most of the RDP traffic will use UDP.

If the UDP connection is not successful or if you select "Use only TCP," all of the RDP traffic will use TCP.

If you disable or do not configure this policy setting, RDP will choose the optimal protocols for delivering the best user experience.
