smb_sniffer module question

[hdm at metasploit.com (H D Moore)]

There is a difference between a login request between a client and a 
trusted server and an inbound request to the smb_sniffer service. Windows 
XP and 2003 will not blindly send password hashes to smb_sniffer (unlike 
NT 4.0, 2000. and Win9x). There are some configurations where the client 
will send these hashes anyways, but this will result in a much smaller 
number of captures when used against a XP/2003 network. Additionally, the 
smb_sniffer code only handles NTLMv1 authentication -- any client 
configured to do NTLMv2 only will not send a valid password hash to the 
smb_sniffer module.
