I need help. A former employee changed the password on win
2000 and we haven't an idea what it is. We installed
windows 2000 on a point of sale system in our retail store
and now we can't get into the system. We can't process any
sales. Should we re-install win 2000? If we do, will the
entire contents of the hard drive be obliterated?
