servers on different subnets cannot see all other computers in dom

We have 6 different sites that all operate on their own different subnets.
these sites are connected together via a fixed lines and can fully
communicate with each other subnet but when you open the network on each
local site, it will only show the computers located within its own subnet.
Each site has its own dhcp server.
we have dns/wins servers located at one site only and every machine points
to these.
there is no name resolution problems.
we are on AD with 2003 on each server.

I would like to be able to see all computers in the domain within network
neighbourhood but cannot find a way to correct this.

Any guidance would be greatly appreciated.

First of all, in order for this to happen, you have to have at least
1 domain in place. This will not work with remote workgroups
because there is no DMB or domain master browser in place
to merge the entire list.

You haven't really mentioned how they were connected aside
from saying you have fixed lines but you didn't mention your
routers. It is common to have 1 machine act as a router with
multihoming which would give you the same result.

Each subnet will have 1 subnet master browser which is
responsible for gathering the local list from all machines
then passing that list on to the DMB as well as passing the
merged list from the DMB back to all clients who request it.
All SMBs must be able to setup a NetBIOS connection with
the DMB(s). This whole process relies on NetBIOS broadcasts.

Hey Mike,

I have a similar issue. All my site are connected via cisco routers. They
can ping eachother just fine by FQDM. We are in a single forest and a few
child domains on different subnets. I can only see machines thats are in
thier own subnet from nethood. How can I get all machine to see eachother in
the entire forest? Do I need a WINS server in every domain?

Thanks

Hi Mark,

Open a dos prompt and run net view against a remote
domain e.g., net view /domain:remotedomainname ;
what do you see?

Hi Mark,

The command is: net view /domainarentdomainname

Use the NetBIOS name not the FQDN.

You, somehow, queried a specific computer for it's
shared resources.

ok got it

from the shanghai server

net view /domainarent.com
system error 6118 has occured

The list of servers for this workgroup is not currently available

when I net view /domain:shanghai (it's own domain) I get

net view /domain:shanghai
Server Name Remark
-----------------------------------------------------------------------
\\SHA-002
\\SHADC01

No. You need just one WINS that all the machines use. "Domains" are totally
irrelevant.

OK here is some additional info from a test I ran.

The parent domain is in NY and we also have a child domain here is NY as
well. We kinda did the single foraet empty root approach. These two domains
are on the same subnet 10.100.0.0/16. Everything communicates perfect b/c
it's the same subnet no router/VLANs separate the two.

I put a laptop from the child domain on it's own subnet 10.200.0.0/24. I
have a router to separate the two subnets. I setup WINS on the child domain
and pointed the laptop to it, rebooted and all the domains show up in
nethood. I can ofcourse connect to the child domain the laptop belongs and
the partent but cannot connect to the other child domain. I get not
accessible error.

So should I setup a WINS server in each domain based on this? Or should I
point everything to the WINS server in the parent domain and try to figure
out the issue?

As I suspected. Have a look at the following:

Internet firewalls can prevent browsing and file sharing
