My new Dell XPS 8100 with Win 7 64-bit: RDP randomly freezes when connected to my work PC which has Win 7 32-bit. I had Win 7 32-bit on my old PC and never had a problem. Now the new PC randomly freezes during the RDP session. I say random because it will freeze during every session but it may be a few seconds or a few minutes before it freezes. If I wait for approx 3 minutes, it will unfreeze for a random length of time before freezing again. Any suggestions?
