[Samba] Help Required !

[Bijo]

Hi,

We have configured samba server(2.2.8a) on linux 7.3 for our Office Lan,
which has got 7 diffrent private subnets(10.1.1.0, 10.1.2.0,
...10.1.7.0/24). After migrating machines from 2 subnets we have seen that
we are able to view all the machines from these 2 subnets from the client.
The plan was the machines in one subnet can see only the machines in that
specific subnet and not other subnet machines. Can you please let me know
how to block this through config file?.

please note that we have done the same setup in one of our bracnh office in
a diffrent location, with the same config and there it is working as normal.
(They can see only those machines comes under in that particular network).
I'm attaching the smb.conf file for our site, please go through it and let
me know where is the mistake I've done or is it something to do with the
network configuration.
