Note that the problem is not limited to Windows - some versions of Samba
have the same problem - and, although it is generally a broadcast problem,
it is occasionally not a Netbios/SMB broadcast.

Fundamentally, the problem is that *nix TCP/IP networking started with the
assumption that a server would have a single adapter with a single IP
address. The "Socket" interface is a standard way of dealing with that
situation. Once you go to multiple adapters, each with multiple IP
addresses, there is no standard interface, and the whole thing is OS
dependent.

I certainly have a lot of sympathy with the samba/linux/OSX/windows
implementations that broadcast packets using the wrong source IP address.
I've tried to find the correct IP address on a multi-homed server and
sometimes there was nothing but pain.

this can happend when the clients are running Windows and when the file
sharing protocol is bound to the tap-win32 adapter - in that case Windows
sometimes uses the wrong source address. Unfortunately, there's little that
can be done about this.
