Impossible to obtain the NETBIOS name of a Win95 box using samba 2.0.5..0

[Herb Lewis]

Unfortunately with the 2.0.x code this will still not work for
Win9x clients if you have nmbd running on your machine. These
clients will only respond to port 137 (which was why you need
the -r flag) but if nmbd is running it has already bound to 
that port and will "eat" your answer so nmblookup will still
not see it. If you must use this and you still want browsing
to work on your machine (you cannot kill nmbd) then you will
have to rsh to another machine not running nmbd and run the
nmblookup command from there.
