The way they used to track us at my old high school was to force us to proxy through an N2H2 server and log all the requests to sites that were not allowed. They also had Centurion cards so we couldn't get virii, etc on the computers.

I've since moved to a new high school with a much more lax security code. First, there are no Centurion cards, and second, all connections are direct(no proxy) with expception to the NAT running at the district center. They also dont have their Novell set up very well(version 3.51, can you say boot up knoppix and have a look at win386.swp after admin logged on). In 5 minutes I managed to get a shortcut to the Control Panel in my personal folder(they disabled it from the start menu), get a command promt, and a list of all student user names. I am not sure wether I want to notify the admin because they might kick me off for general purpose.

Maybe you should try a tracert to google or someplace to see how long you stay in their network and where you go in their network. Sorry if someone else already suggested this.
