Well, just to be clear Sparda, they were not actually asking me to fix the computer. They were just connecting to a network they were not supposed to be connecting to. Secondly, my boss asked me to try to identify who it belonged to and block it's access. Yes I can shut down that port for starters but they could just move to another one. I would like to gather more info and maybe block access to the MAC address. Hmm, maybe I can block that at the switch....
