well you already stated how difficult this would be.... i wouldn't disagree.... its way bigger than just the school, and most likely not worth the effort....

my next best thing would be a per computer per use basis....

which is, yes i know, a pain in the ass, and quite not hacking or cool at all, but it might just get the job done

Unplugging the computer from the network, logging on, and then plugging it back in again does nothing to help the situation as it merely gives you normal account privileges on the computer as opposed to the generally heavy restrictions placed on your usual login. This in no way helps because Sonicwall doesn't care about what account you are logged into on the computer and it blocks your internet still.

Anyways, is their any suggestions for actually attempting this or should I just abandon the thought and move on?

You have the ***** username and Password, how much easier could it get? Just do a little bit of searching around the network...or be like me and copy all of the network files...(like i copied the entire net at my school, and posted the login scripts here lmao)...and then search through it all(it should be too much space, if you get, say, a 4gb flash drive...

EDIT:Thats a great form of reverse psychology...i do the same thing...but i do it cuz im lazy

They were scripts that ran when you logon, so to me, they seem like logon scripts...but call them w/e you like cuz u own me at this stuffs...

Ok, i understand that part, but now you've just made me curious, so whenever i see u on aim ur gonna have to answer some questions for me
