Just got passed this link, and figured I'd pass it along . . .

Forgot your NT admin password?
Reinstall? Oh no.. But not any more..
Offline NT Password & Registry Editor

Overview
This 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 works offline, that is, you have to shutdown your computer
and boot off a floppydisk. The bootdisk includes stuff to
access NTFS partitions and scripts to glue the whole thing together.
Note: It will now also work with SYSKEY, including the option to turn it off!

Why?
NT stores it's user information including crypted versions of the passwords
in a file called 'sam', usually found in \winnt\system32\config.
This file is a part of the registry, in a binary format previously
undocumented, and not easily accessible. But thanks to a German(?) named
B.D, I've now made a program that understands the registry.
As far as I know, Microsoft provides no way of changing the password
if you cannot log in as someone with appropriate privileges, except
restoring the registry files from the rescuefloppy.
You don't forget passwords?
You never get boxes to admin when someone quits suddenly?
Your vendor delivers a preconfigured system to you, but never
have "freak" accidents and lose the password they've set on it?
If so, what are you doing reading this?? Go read propaganda
from your favourite software vendor instead.


Haven't tested this, but heard it works with Win2k also . . .
