Hi Oleg,

I understand, but from what I saw we don't send the NTLM response at all, only 
the LAN Manager
>From your reply I understand that this is also a part of NTLMv2?,
I was reading a tutorial on NTLM and it seems to say that there should be an 
NTLM reponse for both v1 and v2 (though different)
(http://davenport.sourceforge.net/ntlm.html#theType3Message, see relevant part 
below)

Thanks,
Tali.

Responding to the Challenge
The client creates one or more responses to the Type 2 challenge, and sends 
these in the Type 3 message. There are five types of responses: 

LM (LAN Manager) Response - Sent by most clients, this is the "original" 
response type. 
NTLM Response - This is sent by NT-based clients, including Windows 2000 and 
XP. 
NTLMv2 Response - A newer response type, introduced in Windows NT Service Pack 
4. This replaces the NTLM response on systems that have NTLM version 2 enabled. 
LMv2 Response - The replacement for the LM response on NTLM version 2 systems. 
NTLM2 Session Response - Used when NTLM2 session security is negotiated without 
NTLMv2 authentication, this scheme alters the semantics of both the LM and NTLM 
responses.
