DNS records

Posted on 2006-03-21

When I look in DNS manager, I see all of my records. My question is why some of my servers have both a Host (A) record with the hostname of the server and one with the hostname of {same as parent folder}. They both have the same IP address. Why would it have both entries?

    This is because you have numerous domain controllers and we all know that the netlogon service will register this blank domain FQDN (also called the LdapIpAddress) for AD domain communication, to actually identify the DCs.

    You are saying this is why it says "same as parent folder"?

    Yes, because your parent folder is your domain.

    Accepted Solution

    The server registers the default domain record to itself to point DNS clients directly back to a DC.
