cracking a domain cachedump

[slawson]

I guess I didn't make my question clear enough. I will rephrase it. If I have a hash from a Domain Credentials cache dump, can I crack it by using either hash type 1000 or 1100? My testing shows that cracking via type 1100 is about 75% slower.

The reason I ask is because Oclhashcat accepted the hash when I used type 1000, but it didn't crack anything.
