DNS was not setup properly, need to make a choice from 2 options, advice needed RRS feed

  • Question

  • I have been working through error logs and best practice analyzer at a few primary school. None of them were setup correctly but all are working. Basically what I have found is the _msdcs was not created properly by whoever installed server 2003 and it must have been that way ever since. We are currently on server 2008r2.

    To fix the issue I have been told to follow some simple step by step instruction but they give me a choice at the start and I want to make sure I follow the correct choice.

    Case 1: The _msdcs.ForestName zone is a subdomain of your Active Directory-integrated forest root DNS zone, and the secondary _msdcs.ForestName zones are stored in your child domains (if child domains are present).

    Case 2: The _msdcs.ForestName is a subdomain of your Active Directory-integrated forest root DNS zone

    looking at my screen capture which case do I follow 1 or 2? I recon it is 2 but would like someone with better DNS skills to advice.

    If you need any more info please ask.

    These are the instructions I have been told to follow - https://support.microsoft.com/en-us/kb/817470

  • Hi ASnet0007,

    According your description,you don't have a child domain,so I surpose that you should follow case 2.

  • Hi ASnet007,

    Thanks for posting as you are saying currently you have in windows 2008R2 and DNS is not set up properly . _msdcs is created automatically during installation of AD. Try o run the command NSLOOKUP your domain name and update us.

  • Thanks for getting back to me.

    NSLOOKUP - 

    Default server - unknown
    Address - ::1


    BPA reports - Zone _msdcs.........lan is an active directory integrated DNS zone and must be available

    Which led me to https://social.technet.microsoft.com/Forums/windowsserver/en-US/3eca6eba-68ad-43e2-9580-16e72cf8e95a...

    Which has the following,

    Manually create the _msdcs.ForestFQDN. I right-clicked the Forward Lookup Zones/New Zone.../Next/Select "Primary zone" radio button and the "Store the zone in Active Directory" check box (these are defaults)/Next/for replication scope I selected "To all DNS servers running on domain controllers in this domain" (I have a simple single forest, single domain config)/Next/Zone Name: _msdcs.ForectFQDN

    Wait for replication and population of the zone. The population appears to happen automatically (DC,Domains,GC,PDC folders and NS, SOA, and Alias records), be patient and refresh your view on the other DNS servers where you expect this zone to replicate to.

    After more investigation I found this MS KB,
    https://support.microsoft.com/en-us/kb/817470
    Which has the question in my first post.

    Hope that all makes sense.
