You will need to brute force attack the passwords, using a
utility that can read the SAM registry on disk, encrypt
dictionary words, common names, common passwords as well
as generate passwords and compare.

I don't know of such a utility, but I have a feeling that you
might have better luck finding that on Windows. If that is the
case then you could create a WinXP USB drive to boot from.

I find it easier to steal passwords through key logging,
phishing (web or wireless) or social engineering then by
brute force (as a security admin I test out our corporate
environment routinely).
