There a number of similar issues on EE but having looked through non of them relate to my specific experience.
I used RDP to connect to machines at home and at work. Not through a VPN just the local network. But every 2-3 minutes the session freezes, then disconnects and reconnects within seconds and repeats over and over.
I am using Windows 7 Ult to RDP to Win XP, Server 2003R2, and 2008R2.
Since you cant reinstall RDP, is there a repair for this condition?
