  • Hi,
    Please check if IPv6 is enabled on the DC or not, if yes, you could have a try to disable it or move IPv4 higher in the binding order.

  • I see that a PTR record query failed for 1.0.0.127.in-addr.arpa which is normal. I would advise to review your DCs IP settings and refer to what I recommended here: http://www.ahmedmalek.com/web/fr/articles.asp?artid=23

    Public DNS servers should be set as forwarders and not on DCs IP settings.

  • Hi

     Agree to wendy,you should modify network provider order to resolve from Ipv4,check follow the steps on the article;

    https://technet.microsoft.com/en-us/library/cc732472(v=ws.10).aspx

    Then run "ipconfig /flushdns","ipconfig /registerdns".. and check from dns the records update correctly.
