Is automatic replication available for conditional forwarder between DNS cache servers running windows server 2019 or 2022

Question

Hi, all

I am deploying a redundant configuration of DNS cache server with windows server 2019.

I am going to add some conditional forwarders.

So I’d like to know if replicating conditional forwarders automatically is possible/available for windows server 2019.

Thank you.

Hi SK

No, automatic replication is not available for conditional forwarders between DNS cache servers running Windows Server 2019 or 2022. Conditional forwarders are a DNS configuration setting that allows you to specify specific DNS servers to forward queries for specific domains. However, the configuration and replication of conditional forwarders need to be done manually and are not automatically replicated between DNS cache servers.

If you have multiple DNS cache servers and want to ensure consistent conditional forwarder configurations across them, you would need to manually configure the conditional forwarders on each server individually. Any changes or updates to the conditional forwarders would also need to be manually applied to each server.

There is no built-in automatic replication mechanism specifically for conditional forwarders in Windows Server 2019 or 2022. To streamline the configuration process and ensure consistency, you might consider using scripting or automation tools to manage and deploy the conditional forwarder configurations to multiple servers simultaneously.

There are a few reasons why automatic replication of conditional forwarders is not supported:

Conditional forwarders are typically used to point DNS servers to external DNS servers, and it is not always desirable to have these changes automatically replicated. Conditional forwarders can be changed frequently, and manual replication allows administrators to control when and how these changes are made. Automatic replication of conditional forwarders could introduce additional latency and complexity into the DNS infrastructure. If you need to replicate conditional forwarders between DNS servers, you can use the following methods:

Manually create the same conditional forwarders on all DNS servers. Use a third-party tool to automate the creation and replication of conditional forwarders. It is important to note that manual replication of conditional forwarders can be a time-consuming and error-prone process. If you need to replicate conditional forwarders between a large number of DNS servers, it is recommended to use a third-party tool to automate the process.
