Right now it works fine. If enough people at your school abuse the P2P shares, your admin will no doubt go out and get the protocol analyzer add-on for websense and that will bring an end to P2P at your school. The protocol analyzer can block chat clients, P2P shares, etc.

Ya see, when you make a request, your firewall first determines if it has a rule in place to pass the request. If it does it then queries the websense box and asks if it is ok to continue with the request. Websense then looks at your IP/AD account or however your admin has setup the box, and then logs your attempt and either passes it along or tells you to go pack sand in your a$$.

I admin a websense box and while it can be beaten on occasion, for the most part it is a *very* solid program. As for your idea about pluggin in to the school network, yeah, you'll draw an IP address from the DHCP pool in order to obtain connectivity but ultimately the websense box is the authority on what you can and can't do out on the net, not your NT server.
