Well, this option was previously set to yes, and it did not work either.
Changing this, I thought it would make difficult the election of a LMB
on other nets, but you say it won't, so I put it back, and maybe the
other things I changed will cause it to work at last !

Do you have any other ideas about this config ?

Thanks,

Okay, I checked on my clients, and what I see is for the most
surprising: they only display hosts within the samba server's
browse.dat, not even the other hosts on the same subnet (usually, I
believe they would have been discovered through broadcast). So the only
machines that appear on ALL the machines of all the subnets are :
- the server
- the XP box, located on the same subnet as the server

The other hosts' names can be successfully resolved by the server
(checked with Ethereal) when explicitly typed in the explorer bar. But
they are not "discovered" by the network browsing.

Any idea of the problem ?

The local masters don't seem to be doing their job, do they ?

Official Samba HowTo suggests that you would need a WINS server on each
subnet

http://samba.org/samba/docs/man/Samba-HOWTO-Collection/NetworkBrowsing.html#id2588936

You might want to review the documentation - there is a possibility
that
'remote browse sync = broadcast_address_of_remote_subnet'
might work for you.

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.

Not quite!

The LMB does nothing to contact the DMB. The responsibility for browse list
synchronization belongs to the DMB.

The DMB looks for the LMB registrations in the WINS (wins.dat) database. It
then contacts each LMB to synchronise the browse list.

Ergo, if the WINS database does not contain all machines that are LMBs -
browse list synchronization will not happen.
