DNS consiguration question(s)

I have added a new site into my Server 03 AD Domain. Right now there is only one DC in this new site. At this point, this server is providing AD DC, DNS, WINS. DHCP is being handeled by another device in a seperate Domain I am sharing this "Space" with (for now).

I have two other sites: the main site, and a smaller single DC site.

This new site has a pair of linked Riverbed devices between the new site, and the main site.

What I am trying to figure out is:

Network neighborhood from the new DC is SLOW to show me anything. When I look at the list of machines in the domain, this new DC does not show up. I have compared my DNS setup between all three sites, and the only two differences I see are:

The "Other Two" sites have the same set of two external Forwarders in the DNS settings. I believe these are the ISP DNS servers for the main office. The forwarders on the new DC are the external DNS servers from the ISP for that office.

And, Each of the other two sites DC's have an SOA record that basically points to itself, where as the new DC's SOA record points to the main DC server from the main office.

...What am I missing here?

    Accepted Solution

    Your missing NetBIOS protocol or a WINS server.  The Network neighborhood depends on the NetBIOS, not DNS.  If you have no WINS setup, then it is handled automatically for systems in the same subnet.  If you want it to span subnets, you will have to setup a WINS server.

    I just setup a WINS server this morning.
    I will monitor the situation over the next couple days and see how it pans out.
    Can I assume that the SOA record and the Forwarders are both non issues?

    I think so, as far as NetBIOS.  Don't forget, everyone has to be looking at the same WINS server for them to see eachother.  You can also use Browmon resource kit tool to find the master browser, that might help.
