I've asked this question a couple of times but I don't seem to be getting any real answers.
We have a SBS (Windows Server 2008 Rc) server and suddenly the screen has started freezing. Even when we go into the system via remote desktop it worked once or twice (since the problem started), but now the RDP screen freezes once it gets just past the Welcome screen.
The server itself is running, SQL is working, Exchange is working, file share is fine. It's just the UI that isn't working.
We've tried hard resetting and that works for a short while before the problem comes back.
EDIT: When the screen freezes we cannot get access to the operating system at all. That is, we can't access the GUI portion of the OS either via the machine itself or RDP. But, we can still access shared drives, run commands on the machine from a different machine (CMD).
