nmbd & netbios name -> many addreses

[Peter Polkinghorne]

Just an update - I sent more details to Christopher R. Hertel & Luke Kenneth 
Casson Leighton - but working on the assumption it is:

	nmbd-as-WINS -> NT workstation

transaction that is at fault - ie NT workstation is expecting WINS server to 
give it one address for a NETBIOS name, but is in fact given 2 - I used 
tcpdump to sniff between biela - the Samba 2.0.3 WINS server and test-nt - a 
NT 4.0 sp3 intel box - kudos is a multihomed Samba server.

Here is the result (sorry about all the ^M):

callisto.brunel.ac.uk% ~peter/tcpdump-solaris-2.5 -i le0 -s 200 port 137^M
tcpdump-solaris-2.5: listening on le0
