This policy setting specifies whether the UDP protocol will be used to access servers via Remote Desktop Protocol. If you enable this policy setting, Remote Desktop Protocol traffic will only use the TCP protocol. If you disable or do not configure this policy setting, Remote Desktop Protocol traffic will attempt to use both TCP and UDP protocols. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Connection Client!Turn Off UDP On Client (2) REG: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client!fClientDisableUDP
