adding domain controller

[dustin]

I am adding an additional domain controller to my
existing domain. This will be the second AD server.
However, when I run dcpromo I get an error message saying
that it cannot contact the domain and states that it
could be dns problems. I looked at the dns settings on
the DC that I am trying to contact and noticed that the
DNS is missing some stuff. Under forward lookup zones is
the domain name. Under the domain name there should be
some directories like _msdcs, _sites, _tcp and _udp.
These directories are not there. The only thing that it
has is the host files for the computers on the domain and
a SOA record and a NS record. Is there anyway that I can
fix the DNS so I can make this new server an AD server?
Thanks for your help.

Hi Dustin

On your existing domain controller go into the TCPIP properties and make
sure that it points to itself only for DNS. If you have an ISP in their
then add this as a forwarder in the server properties in the DNS snapin.
If the fowarders is greyed out you will need to remove the forward lookup
zone with the name "."

After this is done stop and start the netlogon service. This should
register all the records. If not make sure that the foward lookup zone for
your domain is set to allow dynamic updates(only secure is fine). Once
these are registered point your new DC to your esting DC for DNS and this
should allow youto DCpromo up

Great article on small networks that walks through all of this.
