I think you guys have it right. It is when you try to use Windows built-in remote software because I remember the problem of the GPUs shutting down. If you use a true VNC like TeamViewer or UltraVNC then I don't think there is an issue.

Boy this topic is sure dusting off the old cob webs. My memory isn't what it used to be

When I'm at home (with the computers) I only have 1 machine that has a keyboard, mouse, and monitor on it. The other machines are all controlled with BoincTasks and TeamViewer.
