All is not lost. As long as you can stick a floppy into the Server and boot off of it you can recover/reset the password.

Petter Nordahl-Hagen has a free tool that you can download from home.eunet.no/~pnordahl/ntpasswd The tool uses a Linux bootdisk. There is also a link on the page to a DOS version of the same tool.

to fix this problem you need to do the following steps:-
1- create another group in the domain controller and provide it Administrators privalege
2- create a user in this group and provide him the same access that the group has it
3- log in by this user and go to the local administator of the machine and reset the password
that is all

Try downloading a program called L0phtCrack 2.52 from L0pht.com. That would be a zero not a letter o. This program helps find weak passwords on your NT machine. There's a good chance this prgram will reterieve the administer password. There is a trial version, so there would be nothing lost, and everything to gain.

If the system partition is fat, or you can boot into NTFS (SysInternals ERD commander) and delete the SAM database, NT will replace it upon reboot and the administrator password will be blank. Obviously this is only a good thing if there are limited user accounts and groups on the server. If this is your PDC, there are better although slower way of fixing it.

Are there any users listed as "Domain Admins"? If so, they can simple connect to the machine in question via User Manager for Domains/Select Domain... type in \\machinename... select Administrator and change the password.
If you do resolve this, I'd suggest creating your own ID and adding it to the Domain Admins group (if indeed you should be granted that status). Loging in as Administrator is not commonly considered good practice. Login as yourself, this way you can better track access to your system. If you see someone logged in as Administrator you have no way of knowing who that is. FWIW...
