Cracked windows 2008 r2 hash does not work
I extracted the following hash from a windows 2008 r2 server with iis7.5.


I can easily crack the latter part of the hash. The LM hash seems to correspond a default value (disabled).

When I connect a display to this device, I cannot login to the server with this password using Administrator username.

I seem to be missing something
Are you sure the account is not disabled?
I guess it's possible that depending on how you extracted the hash, you are trying to login onto the domain with the local admin password or vice versa.
