Thought about that but I don't know anything about them. I will have to look and see what there is. Have you used any?

Try Ophcrack. http://ophcrack.sourceforge.net/down...hp?type=livecd
Its a live CD. Download it, burn to disk, and boot the computer from the disk.

This is the one I have used in the past, it worked both times so I never had a reason to experience any others.

I've used Nordahl to bypass admin passwords on NT machines. They claim it will work on all versions up through 64-bit Win7.

I usually use the Ultimate Boot CD (UBCD). They even have a UBCD for Windows that provides a simple XP desktop to make it easier for the computer challenged. It's freeware so there is no cost to try it.

http://www.ubcd4win.com/ The iso download and all the instructions are on that site for the Windows UBCD. It will work with Vista as it uses the same SAM file as other versions of Windows.

UBCD is a good tool it has a lot of disk utilities, diagnostic tools, etc that come in handy. It will show all the user accounts and you can change or blank any of the passwords so you can log in. But... you knew there had to be one right..... if the user encrypted any of the files with Windows you will still need the password to open those, there is no way to change the password or remove the encryption from files.

Checked some of the sites out and they seem a bit over my head at the moment. I almost need a step by step for some of them.

Like Ralff said, skip trying to crack the password. It's an old machine with a horrid operating system. You would want/need the cracker if you were trying to recover data in the original user accounts. That doesn't seem to be the case here.

Just reinstall Ubuntu, W7, or XP (in that order) and run with it. No reason to try and salvage the Vista installation.

Go the safe mode route. If the Administrator login doesn't work, there's a 99% chance it hasn't been activated, and thus has no password protection. To activate, boot into safe mode/dos prompt and follow these instructions:

Change NT Password is a small bootable cd that allows you to wipe the password and unlock accounts. Give it a try. We always used it to unlock PCs before fixing them for the customer (customers were never smart enough to write the password down on the paperwork).
