This is what we noticed in the event log: (infact in the application log
right before the problem occured).
EventID : 1002
The Shell Stopped unexpectedly and Explorer.exe was restarted.
IIS State we did not run continuously. so I have not much from the log which
says that something happened at the time the problem occurs.
