chntpw is a utility to (re)set the password of any user that has a valid
(local) account on your NT system, by modifying the crypted password in
the registrys SAM file.

You do not need to know the old password to set a new one. It detects and
offers to unlock locked or disabled out user accounts!

It works offline, that is, you have to shutdown your computer and boot off
a floppydisk or CD. The bootdisk includes stuff to access NTFS partitions
and scripts to glue the whole thing together.
