I have a Windows7 Ultimate x64 machine that I connect to via RDP from multiple places (a few WinXP/Win7 machines, a few iOS devices using different RDP clients). Everything works like a charm.
But there's this single 32-bit WinXP SP3 laptop that does not work. Specifically, I can connect, I can login, I can even see a glimpse of the desktop, but then the RDP client window just disappears a second or two after showing the desktop. No error messages, no nothing. This same client machine can RDP into other boxes just fine, so the client is not completely broken.
I am pretty sure this is caused by installing some fairly recent windows updates -- if I restore the machine from backup, it works fine until I reinstall those updates. And I would strongly prefer to have the updates installed, for obvious reasons...
Any ideas on how to diagnose/fix this would be greatly appreciated.
