Hello. Can you explain how DNS is integrated with Active Directory during installation ?

Where are the settings stored, how are they replicated, what is the protocol?

    Hi @Андрей Михалевский ,

    Where your DNS records are stored depends on the DNS zone integration settings: If the DNS zone is Active directory Integrated then all records are stored in the Application Partition of the Active Directory database. I would first encourage to read and undertstand the structure of the Active Directory Database.
    Back to your question: DNs records are stored in the Application Partition and this is explained well here:

    What Active Directory Partition Holds the DNS Database (Explained)?

    You can also watch this video:

    https://itfreetraining.com/lesson/adpartitions/#:~:text=DNS%20uses%20application%20partitions%20to,the%20Active%20Directory%20replication%20system.

    So, considering this, DNS AD integrated zones are replicated with the AD replication, which uses RPC as protocol:

    I hope this help you out!

    Hi,

    You can review the AD + DNS integration over here in MS Learn article and this should give you a good starting point to understand the process, however if you have any other queries please ask over here.
