_msdcs missing from domain's forward lookup zone. RRS feed

  • Question

  • Hi There,

    In DNS I have a forward lookup zone of _msdcs.mydomain.com but do not have a _msdcs folder within the forward lookup zone of mydomain.com.

    I think this is causing me some major problems with my domain controllers.

    Can anyone advise what should be in the _msdcs folder and what steps I need to take to recreate it?

    I've attached an image of my DNS config to show the issue.

    Please make sure that the Register this connection's addresses in DNS is checked.

  • If it didn't get created automatically with Jeremy's recommendations, let's go ahead and create it (going from memory):

    • Right-click ResourceGroup.co.uk
    • Choose New Delegation
    • Type in _msdcs
    • Type in your DCs as NameServers
    • Choose AD integrated
    • Allow Secure Updates Only
    • Click OK and finish
    • Go back into the properties, and change the replication scope to Forestwide

    After you're done, it should look like the picture below. There are some notes on the picture, which provides a brief background on the zone. For a full sized image, click THIS.
