I was almost suspended at school eight years ago for using `net send` from .bat files and because I had Everest portable on my network drive (a tool that lists system specs, I was curious what hardware the PC's had).

The guy that managed the network at the time was almost personally offended and accused me of 'hacking' the network with dangerous tools. He got the school board involved, my parents had to go talk to the headmaster. My parents and I had to sign a contract which said that any other 'unauthorised' use of the school network would get me suspended for 3 days.

If you have one bitter person working somewhere and nobody knows enough about something to stop them, you can get these power-mad types. Probably happens a lot at schools with just one network administrator.
