Two questions come to mind.
1: Why is this in the Mac OS X forum when it appears to be a question about Windows XP?
2: Why are you asking us about it instead of taking it to the company IT people to investigate a possible intrusion into their network?
today when i try to log on to network, there is a new logon window besides my normal logon window, if I click this new window, it shows others log on, I haven't seen this before, if it is windows xp, normally it will display the last logon user.
I think someone log on to my computer, how can i check when this guy logon, the user name? any action he did on my computer? he may log on locally or through company intra network. thanks
