Hello, Im new here and I have a simple question. And based on what I've read on this forum I'm sure you guys could help me out. I go to a small school with only about 50 kids and our schools network administrator (who is also the math and computer teacher) thinks hes the crap. For example: Today I was in computer class and since I have already finished the course weeks ahead of schedule, I was working on a website from the school computer. So my netadmin starts screwing around with my mouse and crap with some classroom spy program and then exits out of all my apps and shuts the computer down like the deusche he is. Heres where I stand on the network. Last year, some stupid moron from yearbook left the administrator login password on a post-it note. I try it out and it works. At that time I had no intention on doing anything and wasnt even into hacking. So this year comes around and I want to play a couple "pranks" on my "invincible" netadmin. Just something like changing his wallpaper around to whatever. Theres like 25 computers in the lab, and I have admin privileges on all of them locally. Turns out the admin password for the network that got changed still works if logging onto the local machine. So if someone could assist me in gaining access to network with admin privileges so I can change his wallpaper, it would be greatly appreciated. P.S. I did try running a brute-force on an account on the network with admin privileges which is no longer in use, however due to the slowness of our schools computers, it said it would take 45 days to complete, so that was of no avail.
