For what it's worth, I had a hard time with this when I first
began working with Samba.  I had no difficulty with the Unix
end or with networking in general, but when you're coming
from a Unix background and setting up Samba on your server,
it takes some time to wade through and get oriented with
Windows networking concepts.

I found that the best thing for me was to read the book
"Implementing CIFS".  Even though it's targeted at developers,
it seemed to cover things from a Unix point of view.  I found
that a much more helpful source of conceptual information
than the Samba docs, which are really targeted at the Samba
implementation of the set of protocols rather than the protocols

Based on the log message, it seems that was the
IP of the host that sent the request, not the destination of
the request.  At least that's how I interpret "should be sent
to WINS server".  To me, that phrase means "I got a request
as if somebody thought I was the WINS server but I'm not, so I
thought I'd let you know somebody thinks I am".  In other words, is the address of a misconfigured client.
(Or the server that generated that log message needs "wins
support = yes" turned on.)
