bringing Windows 2008 DC back into my Windows 2003 Domain

I have a small home lab and a year or so ago I decommisioned one of my DCs that was running Windows 2008. Yesterday I tried to bring it back. I booted the old server back up and logged it in locally. I tried to rejoin the domain, but I kept getting a DNS error and the server could not even PING the FQDN of my Windows 2003 DC. I mapped the IP to the FQDN of the active DC using the HOSTS file and finally got it on the domain. I was ready to run DCPROMO, but hit a snag. I start out selecting existing domain and the next screen I tell it to use my current login credentials. This is when the problem starts. I get an error "An Active direcotry domain controller could not be reached" I select details and get the following error;

he following error occurred when DNS was queried for the service location (SRV) resource record used to locate an Active Directory Domain Controller for domain Jim.Fatima.home:

The error was: "DNS name does not exist."
(error code 0x0000232B RCODE_NAME_ERROR)

The query was for the SRV record for _ldap._tcp.dc._msdcs.Jim.Fatima.home

Common causes of this error include the following:

- The DNS SRV records required to locate a AD DC for the domain are not registered in DNS. These records are registered with a DNS server automatically when a AD DC is added to a domain. They are updated by the AD DC at set intervals. This computer is configured to use DNS servers with the following IP addresses:

Is there some kind of DNS entry I need to remove? Any suggestions are welcome,,,thanks

It sounds like this server used to hold a FSMO role. If it was the first DC you had on your LAN & you didn't transfer the roles before demoting it, then this is the case.
Mike KlineCommented:
run dcpromo /forceremoval on your 2008 box that has been offline

 from your current "good" DC do a metadata cleanup for that box that has been offline for over a year

Did that 2008 box hold any FSMO roles; run

netdom query fsmo > to find your FSMOs

If it held FSMO roles you would seize the roles

Once the metadata cleanup is done you can join the 2008 back to the domain and you can promote it again. the way this is an excellent thing to do and learn in the lab.

I am assuming the the 2k3 was the first domain controller installed:

On the 2008 box, for DNS, you should be pointing to IP address of the 2k3 box for DNS resolution.  Also, the 2k3 box should be pointing to itself for DNS, so

IP on 2k3:
DNS: (sometimes set to but prefered to be

IP on 2k8:
IP: (or something in the correct range)
DNS (should match IP on 2k3 box)

More info:
AD must be able to write DNS records on a DNS usually the first DC (the 2k3 box); the 2k8 box cannot find those records and therefore can't find the domain.  You may also want to verify on the DNS entries on the 2k3 box that you have these records populating:

Open DNS, expand Forward Lookup Zones, expand your Domain name, you should see at least four folders:_msdcs,_sites,_tcp,_udp.  If you don't see these (and more) I suspect that the above IP info is not right!   If not, set 2k3 dns to point to itself, reboot and verify.  Then attempt dcpromo!
if u do what mkline says it should fix your issue

Ok this all makes sense now, thanks...I was working on something a year ago and you jarred my memory. I had been hip deep in VMware for the past year, but just got a new job and need to get my basic AD and Windows Server skills back up there....thanks
