when you are running samba , you will start nmbd also which resolves your
unix host on which samba running as netbios
each time client access \\foo\bar, dns will send the request one by one as
you list ips.

i haven't tried that yet, but my intuition is that that would make it 
impossible to, for instance, mount the same share from multiple windows 
hosts. ie


would not resolve, because windows demands an nmb lookup, even after the
host has been resolved via ip. is this not correct?
