How To Change RDP Listening Port - Windows Server 2008 R2 Enterprise

My ISP routinely blocks RDP traffic. Sometimes works and sometimes not. I think they are blocking the port rather than deep packet inspection as it is encrypted via SSL automatically. So I've changed the port to 443 which is never blocked (SSL traffic). You can change the port easily by editing the registry and rebooting: http://support.microsoft.com/kb/306759
