Another way?

You might try this to bypass the windows Admin/user passwords. It can come in handy if you have forgotten the Admin/user/power user password, or simply cannot get access into the system.
It does not require any 3rd party software, simply a bootable floppy/cdrom. It involves renaming the WINDOWS user database file (SAM) effectively resetting all authentication.

To get access into a locked out system, simply follow these steps. It will work on Windows NT/2000/XP including server editions, because of the way authentication is handled by windows.

1> change the boot sequence of your system and set it to boot from the floppy/CD drive.

2> insert the Bootable floppy or CD and power on your system.

3> after the system boots from the drive and halts at a prompt, type the following

cd c: (or wherever your windows partition is located)
cd C:\WINNT\system32\config ( replace c:\WINNT with your windows folder)

now rename the SAM file. The file has no extension so your command can be something like this :

C:\WINNT\system32\config>ren sam sam.bak

Now the next time when you boot, all your passwords will be reset to blank, as windows rebuilds the user database and the SAM file. Possibly all the users you have defined and any domain affiliations may be lost as well.

So use this at your own risk and preferably on standalone machines which you want to gain access to.
