network help

My school, as everyone hear knows, is setup on a network. My network admins dont know what there doing because they had every file on the network able to be accessed till i decided to tell them they needed to get it secure. anyways, now it says i do not have permission to access this file. How would i get around this? i have the main administrators password to can access everything, but i dont want to use that. i want to just raw hack it to where i have full permission to view all files, how can i do this?

Use a Linux LiveCD to copy the files to your "My Documents" folder. :p

Edit: That was a joke… just so people know.

lol seriously, what is there i can do. I already use cain and able to poison all the routers to get all the passwords, but thats to easy, i want to learn and be able to manually do everything.

Use the "cacls" command… take ownership of the files as an admin… I mean, other than boring hash cracking or brute forcing, you could maybe check Bugtraq for some Buffer Overflow vulns in Windows progs… Privilege escalation is the name of the game, and it all depends on what's on the systems.

Anyways, I'm sure someone else has much more to contribute to this than me right now…

alright, ill check out bugtraq and milworm both. also i didnt know that about the cacls command, thanks
