I set it up so that my client could work from her home computer (Sony Vaio running xp home, sp2) using remote desktop to connect to her work (Dell optiplex with xp pro sp2) computer. When she tries to connect she can login but after that she cannot click on anything and eventually that red x icon shows up in the top right corner indicating that the connection is lost. Usually though, the connection stays active and sometimes after a few minutes I can start clicking on icons. The computer can connect to any other machine with no issues, and any other machine can connect to the work PC. Both locations are using a broadband connection and I can do a persistent ping at the same time without losing one packet.
I tried connecting from my own network and still the same problem. It worked fine in safe mode so I disabled antivirus, windows firewall, and everything else I could find in startup but no luck. Finally I decided to format the client machine with a fresh copy of XP and the problem is still there. I switched the nic card, upgraded bios, tried different resolutions and video drivers but this problem will not go away.
This is one of the wierdest problems I have ever troubleshooted. and can't find anything wrong in either computers event viewer. I think I have eliminated software by formatting machine.
Just wondering if by chance anyone has run into anything like this?
