Never knew you could do a remote shutdown like this, but we did find out about a "net send" command to put popups onto other kids' computers.
Later we found a neat exploit / remote access kit, friend of mine could merge the backdoor onto a random .exe file (we used a desktop sheep because ha ha look at the funny sheep). We got that onto a number of school PC's and told people off for using MSN at school for example. I also used it on my parents' computer and found out how much they had on their savings account.
Hazy memory but I forged the NetWare login screen to grab admin password then replaced the original login process with one that logged all logins. Was a moron and left a printout somewhere and I was the first suspect. Had a good relationship with the compsci teachers so I somehow ended up getting a shared office and got paid by the school to secure their systems.
This is true! I also have a good story about how certain network cameras were left unprotected on the school network and some individuals took advantage of that by guessing the default password.
