Paul,

I am aware of tools like asleap and cain and abel that do password
cracking for MS-CHAP, as I tried to explain in my previous post.

What I'm looking for is tools or ways to decrypt the network traffic
when you have the NT hash / password. Hope that clears it up.

Most tools (and there isn't an awful lot of them anyway!) focus on

CHAP(v1|v2). This seems to be an area where some significant papers were

back in the days, but very few tools were actually implemented and
published openly!

If you have packet captures of a tunnel initiation, the username is in clear
text and you can use asleap (http://www.willhackforsushi.com/?page_id=41) to
crack the CHAP challenge/response.
