Reboot to Safe Mode, select Administrator, leave password
blank.
Then go to User Accounts in Control Panel and
delete/change the
password.
You do not need to reinstall if you forgot the admin or
any other password.
There is a boot disk you can download at:

that will let you reset the password of any account on
NT4, Windows2000 or
XP.
Just follow all the default settings which are for the
admin account.
For an Win2k AD domain controller, you need to do more
than that:

I would strongly urge you to increase security on this
system, enclose it in a locked room, with only cleared
staff having access, enable the audit process to kee track
of who logs on and makes whatever changes, and fire the
idiot who altered the password!
