  • my dc has two dns names???

    I renamed my win2k3 dc from srv01 to srv02 and now when I do an nslookup it pulls the same ip address I checked dns forward and reverse lookup and there are no entries for the old name(srv01). what gives? I also did a search in ad and nothing came back with srv01. anyhelp would be great.

    If u change computer names then the ip address should be the same.
    might also want to try ipconfig/flushdns

      When you do an NSLOOKUP, it first returns the name of the DNS server which resolved the query and whether it was authoritative. Then it returns the answer.

      Go to the server which resolved the query and find the "cached lookups" object in the DNS console; right click it and clear/flush the cache. Do this until all the caches on all of your DNS Servers are clear. Then do an IPCONFIG /FLUSHDNS on a client and try your NSLOOKUP again. If it still resolves then more investigation is needed and we'll need to ask more questions.

          I still can't see what is the problem then?
          You renamed the DC name to srv2, why are you looking for SRV1?
          Anyway , the problem is most likely caused (which is not really a problem) , since your DNS is configured to "Secure Updates Only" , that means that when you renamed the DC it renamed it's DNS record with it when you booted the Machine.

          For future reference, questions related to Active Directory/DNS are best asked in the Active Directory forum. One of the MODs will most likely move this shortly.

            I wanted to setup another machine and use the SRV1 name but didn't want to continue until the 'old' SRV1 name was removed from DNS. Thanks for the replys. I removed all references related to SRV1 from DNS and was able to setup the new server.
