domain controller 2016 DNS zones empty

tarek H 181 Reputation points

I dont know what happen after scavenging all DNS records and folders are missing from my only domain controller
i have no backup as i didn't even have time to set up the backup
now i have this - how can i recreate the folders ? they are all missing like dc , _sites,_tcp , etc
I also have these events : The DNS server has loaded the zone _msdcs.Otojuste.local from file NULL on server DC.Otojuste.local. [virtualization instance: .].
The DNS server has loaded the zone Otojuste.local from file NULL on server DC.Otojuste.local. [virtualization instance: .].

looks like a file should exist in place of NULL

    From the test i have done, if the DNS Zone is AD integrated and it has never been changed for a file, you should be able to restart the netlogon service on the DC to recreate all folder /records.

    But if the DNS Zone has been configured into a file, event if revert configuration to AD integrated, you cannot recreate those records by restarting the Netlogon service

    Can you validate if the records are still in the Domain DNS Zone & Forest DNS Zone Partitions ?

    You can see this informations using the console adsiedit.msc

    Click Action / Connect To
    Click on the radio button "Select a well known Naming Context:
    Select Configuration
    Click Ok

    Open the configuration partition and click on CN=Partitions
    On the right side, right click on the DomainDNSZone and click on New Connection from Here
    You will have a connection to the DomainDNSZone on the left side

    Click on the DomainDNSZone on the left side and navigate to CN=MicrosoftDNS
    Under that, you should see the DNS Zones. Are you able to see the different records under each DNS Zones ?

    Do the same thing for the Forest DNSZone

    Also, what is the Scavenging configuration for the Refresh interval / No-Refresh interval ?

    Hmmm... that's weird... normally a scavenging does not delete this...

    Have you tried to restart the netlogon service on the DC ?

    net stop netlogon && net start netlogon

    Does the zones were AD Integrated of in a file (C:\Windows\System32\dns...) ?
    By default, the DNS zones are AD Integrated.
