DHCP and a big damn wall (Score 1)

Make all of the Dorms DHCP while the classroom and administration buildings are Static IP, then seal them off from each other. The only place both should have access to is the school mail servers. I work for one of the top five wired schools in the nation, and students can only see other dorm shares. Students use Peer2Peer or just run through Windows shares. It runs most of the time and issues only really arise from ground seep taking out major wiring and occasional lose of our connection to the outside world from unexpected circumstance.
