Win 2000 computer name and netware login

Can any one help. I work at a college as a technician where the computer labs have recently started to be defaced and damged.
What I would like to do is when some one logs in with Novell client 2000 to a windows 2000 proffesional PC a log is created that lists the users login name, time, and the full computer name that windows 2000 uses.
any ideas would be greatfully recieved as our IT department tells me that it cannot be done.
