DNS error when trying to run DCpromo on 2003 server

When running DC Promo on a 2003 server, the following error is received :-

"The following error occurred when DNS was queried for the service location (SRV) resource record used to locate a domain controller for domain Martek.com:

The error was: "This operation returned because the timeout period expired."
(error code 0x000005B4 ERROR_TIMEOUT)

The query was for the SRV record for _ldap._tcp.dc._msdcs.example.com

The DNS servers used by this computer for name resolution are not responding. This computer is configured to use DNS servers with the following IP addresses:

10.0.0.50

Verify that this computer is connected to the network, that these are the correct DNS server IP addresses, and that at least one of the DNS servers is running.

----------------------------

There is currently one 2000 server running as a DC already. We would like the troublesome 2003 server to act as a peer DC in the same domain. The network is a single subnet, and the 2003 server is working fine as a member server on the example.com domain. Some help would be much appreciated !!!

Is the DNS server at 10.0.0.50 authoritative for your domain?  Are you sure that is the correct DNS server that is hosting your internal AD records?  If that is the correct DNS server have you tried to see if you can ping it?  Perhaps there is a network problem preventing you from contacting that server.

Brian, the 10.0.0.50 machine is the DC and DNS server, and authoritative for the domain. Yes you can ping it, both servers communicate!

I wouldn't take those steps just to recreate some records if this is a production DNS box.  All you would have to do is type "net stop netlogon" and then "net start netlogon".  

Also make sure that your current DNS server is allowing Dynamic Registration of records.

thats some good advice mkbean!! thanks ill do that. I was weary of those steps also, as it is a production server. Will the net stop, net start command recreate the missing srv records? also will it cause havoc with a live domain ?
BrianIT ManagerCommented:
It will re-register SRV records and may cause a slight amount of downtime do to the netlogon service restarting.  In my experience it has not been longer then 30 seconds.

thanks Brian, if this works youll get plenty of points ;0)
mattacukAuthor Commented:
OK, I have looked at the Server and it has no SRV records at all for AD !!! - this is of course the problem. It does have forward and reverse lookup zones for the domain. Whats the quickest was of adding these AD services to DNS ? will the net start/stop add these if they are not present at all? or will we need to recreate the zone? (which id not like to do if poss)
BrianIT ManagerCommented:
Yes net start/stop will reregister those records as long as the DNS server is authoritative and Dynamics updates.

Brian
mattacukAuthor Commented:
Brian, thanks for your help its much appreciated. Ill try the net start/stop. Tell me, how do i tell if its authoritative ? is it the SOA record ?

Looks like there useing static IP config, which is bad. I dont know who set up the network, but im worried this might complicate things further. Will DDNS work with clients useing static IP configs ?
BrianIT ManagerCommented:
Yes DDNS will work with those clients.  You may want to try an ipconfig /registerdns to verify it adds a new record.

Thanks Brian your the man! will let you know how it goes. If the net start/stop doesent work, and i need to resort to recreating the zone. If i point the clients to an external dns server while i recreate the zone, will they be ok for loggin in and out of the domain?
BrianIT ManagerCommented:
No it won't since when a client logs on they contact DNS, and DNS uses those SRV records to redirct users to the domain controllers.  So in short, as a last resort that will work but do it during off hours.
