RDP, ie 7, vpro not working on half of my servers

I have placed 13 new computers in the office in the last few days. My computer was the last one, for now, to go into effect. My computer is a VPro, 160Gb HD, 4 Gb RAM, Windows XP SP2 and the latest version of RDP.

All computers can use the Remote Desktop Connectioin and connect to all servers without issue. However, my computer is another story. Every time I try to connect to about half of my servers, I receive a “The remote computer disconnected from the session due to a licensing issue” error. I have looked at every article I can find, I have done everything I know to do. All other servers and workstations work flawlessly.

Anyone have any ideas?
