What's the best way to set up DNS servers for remote offices?

    Question

  • I run into a problem with DNS record updates. We have remote offices and their DC or RODC is set up as local DNS servers that their local PCs and servers use as their primary DNS server.

    However, somehow their PCs and servers' DNS records are not being updated in our main DC/DNS server in the central office. The DNS records were updated locally but not replicated over.

    What did we do wrong?

    Hi,

    Since you installed DNS on DC, zone would be transferred during AD replication.

    In this scenario, I recommend to check if any error occurred during AD replication.

    In order to audit AD replication, you can try this:

    Are they (remote offices) supposed to be set up as secondary or primary zone? It looks like they are all primaries.

  • Hi,

    Because only primary DNS zone records can be stored in AD database.

    If the remote domain is one of your subdomain, you can configure a delegation between you main office and remote office.
