I found this for W2K - could work as well

Quote:

In fact, if you've installed Win2k on a partition formatted with FAT or FAT32, it's not all that hard:

Boot your computer using a DOS or Windows 9x boot disk.
Type:
CD C:\winnt\system32\config

and press Enter to change to the folder where your passwords are stored. (Of course, if you've installed Windows to a folder other than C:\winnt, you should substitute the correct folder name in the command above.)

Delete the SAM file by typing:
DEL sam.*

and pressing Enter.

Remove the boot floppy and restart your machine.
When prompted for a logon name, use Administrator with a blank password.
One word of warning: The SAM file defines all the user accounts on the computer. When you delete it, you'll lose all user accounts.
