Subject: Best way to crack NT passwds

Yup after I posted that I read your post, have to admit, searching a 
table full of hashes would be a hell of alot quicker than cracking it 
manually :]
But then again, I rarely crack any hashes (good memory for my own 
passwords) but anything for md5 i use passcracking.net/com.
But i suppose it wouldnt be difficult to code up a quick php page to 
fill a mysql dbase with incremental hashes generated on the fly... might 
look into it
(even though its no doubt been done) fun project for a rainy day i suppose.
