Error during DCPROMO: Diagnostic Failure

Microsoft Microsoft windows 2003 server...

Specs: Windows Server 2003 SP2, Intel Zeon
I am trying to install active directory using DCPROMO on a Windows 2003 server SP2. I have setup static IP addresses. When I get to the DNS Diagnostic I get an error about dynamic updates. Could someone please give me an idea at to how to correct this problem?

I have not setup DNS manually prior to running DCPROMO. I trying to have the server handle the DNS locally to speed up the DNS resolution, hence I’m try not to use a forward lookup zone. This is the first and only server. It will have internet access but we don’t planning on registering the domain. The server and error details are below.
IP: (Server Address)

dns1 (
dns2 (comcast dns1)
(the numbers above are for testing only and will be change)
currently the router has the firewall off and the server is located in the DMZ)

Diagnostic Failed
The registration diagnostic has been run 1 time.

Warning: Domain Controller functions like joining a domain, logging onto a domain, and Active Directory
replication will not be available until the DNS infrastructure for Active Directory is correctly configured.

The DNS zone authoritative for the domain cannot be updated because it is the DNS root zone. Domain controllers will not send dynamic updates to the DNS root zone. If you want to use this domain name, select 'Install and configure the DNS server on this computer' below and create a delegation for the new DNS zone from the root zone to this DNS server.

For more information, including steps to correct this problem, see Help.

The primary DNS server tested was: (

The zone was: . (root)

Domain controllers will not send dynamic updates to the DNS root zone.

"hence I’m try not to use a forward lookup zone."

You can't be the "root". First error.
Second error its clear you don't understand how dns works. No forward lookup zone = no dns.

This will get you started concerning the root zone but you should readup on MS DNS config

Answers are only as good as the information you provide.
