NSLOOKUP shows old domain controller IP address mike11d11 <mike11d11[ at ]yahoo.com> 12/18/2008 12:37:11 AM I'm getting some errors on a few client computers when logging in from the event viewer. The are getting error 1053 saying user or computer not found. Also message about not able to find domain controller. We have removed and old 2003 SBS domain controller from the network and now only have a windows 2008 and server 2003 standard machines as the only 2 domain controllers left on the network. When i do a nslookup for our domain on a machine i'm showing it still has the third IP address of the old domain controller. I'm not sure where i need to go in DNS to clean this up. Machines seem to be trying to connect to the old domain controller and retrieve gpo's and I beleive DNS is the issue. Any help is appreciated...

Did you also cleanup AD sites and services from the old servername?

Re: NSLOOKUP shows old domain controller IP address mike11d11 <mike11d11[ at ]yahoo.com> 12/18/2008 2:55:26 PM Under sites adn services i still see the old server listed there. It doesnt have any settings under it like the NTDS Settings, its just the server. I guess i can just delete that server from the list now. The old server is just a member server on the domain now, would removing it as a member server get rid of the listing? We do not use this server right now for anything anymore. Within DNS, i go to DomainDNSZones and a Host (A) record for the old server. It also has a Host (A) record under the ForestDnsZones for the old server as well. Should i just delete these or is there a proper procedure for removing these from the Zones?

How was the SBS domain controller removed? Did you demote it using DCPROMO, or manually unplugged it? If manually unplugged or blown away, you may also need to do a Metadata Cleanup. How to remove data in Active Directory after an unsuccessful demotion (of if it failed, unplugged, etc): http://support.microsoft.com/kb/216498 Also follow Meinolf's suggestions to remove it from Sites, Nameservers tab in DNS properties, and anywhere in the SRV records. You can also cleanup the SRVs by performing the following on each DC: delete the system32\config\netlogon.dns and dnb files. ipconfig /registerdns net stop netlogon net start netlogon Ace This posting is provided "AS-IS" with no warranties or guarantees and confers no rights.
