OK, here's a few links I saw for getting the NT password:
NTPasswd: http://home.eunet.no/~pnordahl/ntpasswd/
Knoppix-STD: http://www.knoppix-std.org/
SAMInside: http://www.insidepro.com/eng/saminside.shtml
LC 5: http://www.atstake.com/products/lc/
NTPasswd looks like the easiest way. Burn the CD bootdisk, follow the directions on the web-site.
Knoppix-STD is full Linux system on bootable CD with some hacking utilities. you put the CD in, boot the machine, and the Linux operating system boots off the CD. I don't know what utilities come with the CD, but I'm sure their web-site can help out with that.
