HI I have question about default zone _msdcs.root.forest.net. I have promoted new tree domain in existing forest, domain controllers is replicating fine with root domain, but on new tree domain controller DNS this zone is missing. When I check _msdcs.root.forest.net on root domain, zone is configured to only replicate all domain controlers in this domain (for windows 2000 compatibility), its necessary to change replication of this zone to all domain controller in forest ? Is there some chance to broke something. On root domain is bunch of old w2008r2 controllers and others is w2016. Its safe to change this?

    Well i have use condittional forwarder in root domain, which point to tree domain dns and it works, also in tree domain also works conditional forwarder to root domain dns servers, question is that is neccesary to replicate _msdcs.root.domain.com to treee domain DNS server, by default it is replicated forest wide but in our case zone is only domain replicated in root domain, for unknown reason.
    Thank for your sugesstion DSPatrick.

    Hi there,

    The cause of this issue is that, in the DomainDNSZones partition, we already have an entry for this Zone. Changing the replication scope tries to recreate the Entry which Conflicts with the existing Entries and hence does not allow.

    To resolve this issue, the following solution is considerable:

    1. Change the Zone type from Active Directory-integrated to Standard primary Zone
    2. Go to adsiedit and connect to DomainDNSZones

    Here is a thread as well that discusses the same issue and you can try out some troubleshooting steps from this and see if that helps you to sort the Issue.
