I'm not going to argue with you but I will point out the Samba
documentation that covers this...


from which I quote...

"Right now Samba WINS does not support MS-WINS replication. This means
that when setting up Samba as a WINS server, there must only be one nmbd
configured as a WINS server on the network. Some sites have used
multiple Samba WINS servers for redundancy (one server per subnet) and
then used remote browse sync and remote announce to effect browse list
collation across all segments."
