Computer access in evenings
Hi,
I have a coworker who has been found to have been going on another person's machine in the evenings and has changed architectural drawings that the person who's machine it is has done earlier (by scaling them down .9822 or more % depending on his mood),. this has been found to have been going on for at least a year... proof is the log in the hardrive (event viewer, System log and application log) showing someone logged in a couple of hours after the other left. And there are other things like security code for building was signed out last by this individual as well as discovering that the drawings this individual was working on were saved at the same time... the partners want the person whose machine was accessed to let it slide.
Please advice?
