We have a LAN with three WIN XP SP2 systems and one WIN ME system, all with access to each other and to the internet via a router and DSL modem. We want to move the WIN ME system to the semi-public room outside the office and use it for teaching via our wireless connection and the internet. We expect eventually to let some teachers and students use it locally.
The problem is that we don't want to compromise the security of the three machines that are still in the office. WIN ME doesn't seem to have real security. So I'm wondering if there is an easy way to set up the WIN ME machine so that some random person in the public room couldn't turn it on and gain access to the machines in the main office. It might be OK if the person, who might be a student or teacher, could access the internet only.
The minimum scenerio would be something like this: The WIN ME computer would sit in the semi-public room. For certain classes, the teacher of the class would be able to turn it on and use it in, e.g., a language class, by using the internet. After the class, the ME computer would be turned off. In the meantime, if somebody else came in an turned on the ME machine, we would want that person to have no access whatsoever to the XP machines on the same network. If it could be arranged, that person could surf the web, but that isn't a requirement right now. And the person would not be able to change the name of the computer or user, or fool around in other ways to gain access to the other machines.
It is also the case right now, that all the XP machines have the same user name for users and administrator. It would be nice if the people in the office didn't have to login and logout all the time.
