LophtCrack and SAM Passwd

["William Woodhams" <William.Woodhams () wegmans com>]

I have a system that recently got hacked and the passwords on the
machine were compromised.  I want to get back into this system for
forensic reasons.  Unfortunately when I dumped the SAM file and tried
cracking it with LophtCrack nothing worked.  I ran it for a good 10
hours with no success on any account.  I was thinking maybe my word list
was not big enough.  So the questions are:

A.  Anyone have any good sources for large word lists?
B.  Any other application for cracking SAM's that I have not thought of?
I have ran it through a couple smaller security apps (names escape me at
the moment.)

Thanks,
