    Hi,

    When I execute dcdiag /test:dns /dnsforwarders /v.
    Please find the below details:

    Summary of test results for DNS servers used by the above domain controllers:

    DNS server: 10.176.0.17 (<name unavailable>)

    This is a valid DNS server.
    Name resolution is funtional. _ldap._tcp SRV record for the
    forest root domain is registered

    I just wanted to know why the name unavailable is appearing side to dns

    Have you implmenented reverse lookup zones for the subnets where DNS servers
    are residing on?

  3. Have you created the reverse zone? It doesn't appear that you have.

  4. Your reverse lookup zone is missing thats why you are not able to resolve IP
    to hostname.
    Create a reverse lookup zone for the said IP subnet.
    Create pointer record for the server and run dcdiag again
