ok... nice

but what happens when the system is so secure that they even blocked command.bat

and also, what if there is no possible way to inset a disc to upload that program?

i really need advice on this, because I really wanna leave a mark on my school before I leave, and I think being able to crack into the system, making an admin account, sending out a word document to all the student accounts telling them the new admin account username and password, and watching all the faculty tripping over their asses trying to delete the account (even though their OWN SECURITY blocks you from doing that, regardless of admin status or not), would be priceless.
