We are set up as a Domain and we do not seem to experience the problems that you are refering to. We have just added a wonderful program called Deep Freeze to our build. Deep Freeze automatically shuts down computers and prevents students from loading unwanted material onto our computers. When I was visiting the Language Lab at Cornell I noticed that they are also using this program... Have you spoken to Nils Sodderman about your dilema?
