Hello, I've got 7 Dell Optiplex 755 running Win XP on a 2003 Standard Domain. Every couple of logins the computer will just freeze on a blank desktop screen, and will not respond to commands. (This occurs immediately after entering name and password and pressing enter to log in.) I have to do a manual shut down every time this occurs. It used to happen to only one of the machines, but now has spread to three others.
After I restart, everything is fine
