Take a look here:

This is a Linux boot disk that will let you reset the password to whatever you like. The whole process only takes a few minutes.

Good luck, hope this helps!

Do you have another account with administrative rights? If yes use that account to reset your password.
If not:
The object is to gain access to your File System and change the cmd.exe file from cmd.exe to logon.scr (and the logon.scr to logon.old,so you have a backup). They are both located at c:\WINNT\System32. That way when your OS boots you can wait for the screen saver to start working (don't touch the mouse or keyboard), once the screensaver is running (now it is the command prompt) usethe net user command to change the password for the administrator.
Here are a few ways you can access the file system:
1. If your boot partition is FAT, just boot using a win98 boot disk.
If your boot partition is NTFS:
2. Using a Lynux boot disk and mount the NTFS volume then rename the files as above. Don't use lynux if your boot partition is part of a software RAID.
3. Remove the Harddrive and install it into any other computer that has NTFS support (WINNT/2K, if it is a Win2K machine don't put it into a WINNT machine). Using a local admin account on the new comptuter follow the above steps.
4. Install another instance of WINDOWS NT/2K (dual boot) and boot to the new installation, browse to the above files and rename them as above. Reboot boot into the old version of Windows and wait for the command prompt.
The above works becuase the screensaver runs as the system account which has permissions to change everyones password.

That easy... If you have the correct tools. There is and appication by WinTernals call ERD Commander: Read what I have cut from there web page:
"ERD Commander provides a set of tools on a single bootable CD that will help you troubleshoot and correct many common problems that can occur on Windows NT (service pack 4 or better is recommended), Windows 2000, and Windows XP. It runs automatically from a bootable CD-ROM, which you can either receive from Winternals directly or can create from a CD image you obtain electronically. This tools CD provides you with full access to dead systems by giving you the means to recover and reset administrative passwords, edit the system Registry, enable or disable services and device drivers, and search for files. The latest version, ERD Commander 2002, works with Windows XP, provides you with Network Neighborhood browsing (a Notepad-like interface for editing text files), and gives you access to the system event log?all through a Windows-like graphical user interface (GUI). "

It really works expensive but worth the investment!

been there ..... done that.
Boot NT with the setup disks (which you can create). Select install Windows NT. Your existing installation will be shown. Important: select "N" to install a new installation (not upgrade) and install into the existing installation leaving file system intact. This will overwrite your security and account information. After rebooting you will be able to skip most of the system GUI setup and have access to your system mostly intact.
