OK correction...I have it on good authority that I have given bad advice
above...

1 - only 1 WINS server
2 - remote browse sync is not what you want
3 - clients need to have proper configuration of WINS server address -
if by DHCP, then you probably need to set the node type (option 44/46)
correctly
4 - OP should check contents of wins.dat (on my RH systems, they are
located in /var/cache/samba but on others, they are in /var/lib/samba
YMMV)

WINS uses UDP unicast (directed UDP) which is routable. What you have referred
to is known as "NetBIOS helper agent" - a router configuration option that
can perform forwarding of NetBIOS UDP broadcasts. This option is a VERY bad
thing and is totally unecessary if WINS is correctly configured and if
clients are working as they should.

Ah! Does your DHCP settings include "option netbios-node-type 8"?

Wrong! WINS uses directed UDP. Directed UDP is routable. Does your router pass
directed UDP packets?

Check your wins.dat file on hgsserver to see if all clients have registered
with the WINS server.

Yes, they have, and the infos are accurate. NetBIOS name resolution
works perfectly. The problem is about browsing.
