  • Cannot add child domain

    "an active directory domain controller could not be contacted.ensure the dns name is typed correctly.if the name is correct click details for trouble shooting" NOTE: the error returned indicates that the AD wizard was able to find the SRV records for the primary DC.

    The above is the error that my client gets when he is trying to promote a member server to a DC in the current domain/forest to be part of the existing domain/forest but to be a child domain.

    An A record for the DC does exist in DNS and nslookup returns the correct A record aswell as the member server being able to ping the DC via DNS. The server being promoted resides in a diffrent subnet but routing is not an issue as the member server is able to resolve DNS entries in the adjacent subnet as its nic is pointing to the root domain controller which is also a DNS server.

    Is it best practice to create the DNS zone first on the PDC?


    Any ideas guys?

    There are log files on the server you are trying to promote, located at c:\windows\debug. Inspect dcpromo.log and dcpromoui.log files - this should tell you where exactly the DCPROMO is failing.

      dcpromoui 7E0.254 0171 DNS was successfully queried for the service location (SRV) resource record used to locate a domain controller for domain domain.com:

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

      The following domain controllers were identified by the query:

      server.domain.com

      Common causes of this error include:

      - Host (A) records that map the name of the domain controller to its IP addresses are missing or contain incorrect addresses.

      - Domain controllers registered in DNS are not connected to the network or are not running.


      This is the following in the logs. Note currently the server is in a workgroup. Is it advisable to ensure the server is on the domain first before it is promoted?

        Re: Cannot add child domain

        Is the server pointing to a DNS server in the forest root domain ?

          Re: Cannot add child domain

          I managed to resolve the error. The server in question to be promoted was in a diffrent subnet. The router/gateway that the server was pointing too was inappropiately configured to forward LDAP and DNS traffic. He has since changed this and is able to promote the server. Many thanks for your input.
