This will let the Windows NT or Windows 2000 to use CMD.EXE command prompt program as the screen saver that will be activated after computer idle for specific minutes.
- Ensure that you activate the screen saver of the Windows.
- Wait for the computer screen saver activation idle wait time timeout, so that Windows will load the unprotected DOS command prompt in the context of the local system account as if it¡¯s the screen saver.
- In the CMD command prompt that is opened, key in the following command to reset and change the administrator¡¯s password:
net user administrator newpassword
And the user account for administrator will have the new password of newpassword (which you should change to your own password). With the syntax of net use user_name new_password, it can be used to reset or modify the password of other administrative user account¡¯s passwords.
- You can now log on to the administrator account with the new password. You may want to replace back the original LOGON.SCR that has been backed up or renamed.
- You may want to delete the alternate installation of Windows, by deleting the installation folder or format the partition (if you install in different partition), and removing the second Windows entry in BOOT.INI file at the root. Use attrib -r -s -h c:\boot.ini to change and allow the boot.ini to be modified and viewed.
Unless you¡¯re using Windows NT 4.0 computers that were installed out-of-the-box that set the NT¡¯s default permissions for Everyone to Full Control, you most likely will have problem to rename, change or delete the files located in \Winnt\System32 or \Windows\System32 folders if you log in as the non administrative regular user, as regular user cannot manipulate the files¡¯ permissions.
In this case, install an alternate second copy or Windows NT or Windows 2000 (make sure it¡¯s the same version with the existing OS which you have forget the password installed), and the new install of Windows must be installed in different directory/folder from the existing Windows, which usually located in \WinNT or \Windows, or install the new Windows on another partition or drive. Alternatively, you can take out the hard drive (where you lost the admin password) and place or install it as a slave on another computer with any OS such as Windows XP or Windows 2000 installed. The purpose is to access the %systemroot%\System32 of the OS that you have lost or forgot the administrator password, and does the modification specified above.
After installing the alternate copy of Windows, or install the hard disk as the slave disk to another Windows in a computer, boot up the system with the alternate Windows. If you install the second copy of Windows on the same machine, go to Control Panel -> System -> Startup (NT) or Control Panel -> System -> Advanced -> Startup and Recovery (W2K) and change the default boot instance back to your original instance of Windows. Then follow the step 2 to 4 above. After done, reboot and restart the system and bootup to the original instance of Windows (if you take up the hard disk to another machine, now put it back to the original computer), and continue the rest of steps from step 5 onwards.

Hi,
There is a tool which automates this process and will even create a bootable .iso for you to burn to CD.
The tool is called DreamPack PL and can be found at:

Note; The background music on this site is loud and annoying. Switch off your speakers before visiting.
This tool will work on Windows XP.
Kind Regards
