  • As far as I know the domain join process is not dependent on that. DNS registration could come after join process.

  • for joining domain, only the path to the domain controller is enough, no need of A records for the server being joined.

  • The QIP would surely have some records for the domain controller, since it should be holding the zone.

    go to nslookup

    type "set type=a"

    <Domain_FQDN>

  • thanks for the reply. i was confused.

    you are right, domain join is not dependent on A record. To join a computer to a domain it should only be able to find the domain controller, not the A record.

    A records are only to resolve hostname to IP.
