Win NT , how to break admin password?

[vanln]

Hello Bro,

At my work place, we got some computer missing admin password. I tried to recover . Did any body have a good way to break it? I remove the hard drive to another computer as slave drive. I'm able to see those file. I 'm thinking to override the password by copy the admin file from other computer and paste to the hard drive that have missing password. Do anybody now which file that I need to copy??

Thank for response

There is a trinux bootdisk out there that is used to make a new NT password. Do a google.com search for it, or wait for someone to post a link, and you can change the password.
