Hello, works for me (i386), resetted my mothers password :)
jirib chntpw is a Linux utility to (re)set the password of any user that has a valid (local) account on your WinNT or Win2000 system, by modifying the crypted password in the registry's SAM file. You do not need to know the old password to set a new one.
