NTLM hash, how practical is it?

[ToJ]

May I borrow this thread a little? I have a pwd dump file from Win Server 2008 and I need the admin pwd (the one who set the pwd died, unfortunately).

The file (say ha.hash) is on the format:
Administrator:500:NO PASSWORD*********************:[32-Char Hash]:::

How do I get oclhashcat to start cracking this password for me?
