You have a problem resolved many times and documented somwhere in samba
However, there are some experiences explained (hope you will understand
my bad english:( )

First of all: The windows smb protocol discovers machine on a brodcast
basis, so if you have two separeted subnets the machines of one subnet
do not see the ones of another subnet.

To resolve this and other weird problem with broadcast discovery, wins
were introduced. The wins server may reside in any subnet, the ckients
must be configured to connect to wins server.
Once a client come up, it register himself on the wins ang get back the
list of currently registered machines, then it will resync every
x-minutes with the wins to get updated browse lists.

At this point however you have two scenarios:

1. you have only workgroup and no domains, once wins is activated, after
some minutes(or hours) the wins clients should see all the other
registered clients.

2. You have domains.
In this case you will probably see al the windows domains but you can
access other domains only if the other domain server permit this (the
last statement is based on personal testing).

So if you have more subnets you should really use a wins server (this
will reduce also the brodacast trafic), if you have domains you should
grant correct permissions (trusting) to access others domains.
