samba - Feb 2005 - no session setup connecting from xbox

Hi All,

I am attempting to connect to a Samba server (version 3.0.10) from my  
xbox running MAMEoX, a port of MAME to run on the xbox. When the  
program attempts to connect, Samba terminates the connection. Looking  
at the host log, the relevant line is:

smbd/service.c:make_connection(735)
   make_connection: refusing to connect with no session setup

I have successfully connected from MAMEoX to a Windows machine with a  
share. I have also successfully connected to the Samba server from Xbox  
Media Center, another application on the Xbox. I have captured a  
loglevel 4 (more readable) and loglevel 10 transcript of the session.  
You can see them here:

I've scoured Google/Usenet for information on this, and the closest to  
an answer I've found is this:

Any ideas? Let me know if there's any more information I can offer.

Thanks!
