bypassing logon in win2k

Hello,
My company unexpectedly fired one of our managers yesterday. When I was asked to retrieve any business info I could off of her PC, I found that her PC was not configured to run on the network. All of her data is on her hard drive. The guestaccount was disabled, and I don’t know who set the PC up initially…so I don’t know the adminstrator password. I obviously don’t know the password of the person fired, either. In Win2000 there doesn’t seem to be a way around this, like there is in win98. Any suggestions?
