Huh? Why would the nmbd perform the same way that the multi-homed NT box
does? It's not the nmbd platform that's multi-homed.

Okay, that's between the multi-homed box and the NBNS (WINS in this case).
The traffic Peter is asking about is between the NBNS server and a client.
Multi-homed-server <=====> NBNS <=====> Client
Not this bit
When the client sends a query to the NBNS regarding a name on the
multi-homed server it gets back a list of IPs, so it fails to resolve the
name. As a result, the client cannot access services on the multi-homed
host. This may be Microsoft's bug, but it's a bug none-the-less. It
prevents users from accessing services.
So, two questions:
1) Is Samba's NBNS (in nmbd) replying just like NT WINS to queries when
the name is from a multi-homed host?
2) If nmbd is behaving just like NT WINS, is this basically broken and
should we offer an option to fix it?
