Yes, thanks. I also noticed the code in head which expresses essentially 
the same things.

I am interested in whether it look like NDR Encoded stuff as well. I will 
probably spend a small amount of time getting the NTLMSSP dissector to 
decode it as NDR to see what it looks like.

The list desctription for the BLOB within the BLOB looks spot-on. How did 
you figure that one out?

Richard,
Please see my previous posting on this:

The middle describes the NTLMSSP challenge.  The ULONG of zeroes is the end
of the list (address type 0, length 0).

It's probably time to gather the info up into one place, so we don't have
too many people rediscovering the format...you and I are certainly not the
first ones to do this.
