There is a program I use at work to get around peoples passwords when they forget to tell me what it is or if they have forgotten it themselves. Its called Winternals ERD and when you restart it will boot up off the cd and allow you to change the password on any user and lots of other stuff. I think most of the programs you have to buy but you should be able to dl winterals easy of a p2p program or something. They may even have a trial.
