Isn't the system simply configured not to store the LM hashes, but
rather the NTLM hashes only? Is there a
key set in the registry? That disables the storage of LM hashes -- and
the best way to use it is to set passwords to something noone would
use as passwords (say something prevented by password policy, like empty
passwords, or very short ones), then disable LM hash storage by setting
this key, and then set the new passwords. That would produce the situation
you have, if I have understood it correctly.

You don't say how you ran LC3 -- did you try to crack only the LM
hash, or both?
