Subject: NTLM cracking

Folks,

(sorry about spamming).
I have found what i needed in the first place, this article/response
describes what i have to do to crack NTLM passwords:
http://www.openwall.com/lists/john-users/2006/07/08/2

I quite happily ran this command: john -show pwfile | cut -d: -f2 > cracked
However, im getting: Unknown ciphertext format name requested when i run:
 john -w=cracked -rules -format=nt pwfile

Yes, i have done the following:
In john.conf (or john.ini if you're running on Windows), rename the old
[List.Rules:Wordlist] section to [List.Rules:Disabled] to deactivate it.
Rename the [List.Rules:NT] section to [List.Rules:Wordlist].

I'm running john 1.7.0.1 under windows 2k3. Any hints would be great!

Thanks much
