How to update multiple DNS servers when failover occurs

Table of contents

Overview

This article explains how to update multiple DNA servers when a failover occurs. For example, if you can't use the HA integrated DNS update for the virtual hostname, you can continue to use the DNSCMD.EXE that the failover engine used.

Goal

After completing this how-to you will know how to update multiple DNS servers when a failover occurs.

What to do

The following link shows an example PowerShell Script Microsoft has posted, which can be executed as an alert action when a failover occurs, similar to the Orion out-of-the-box alert to update the HA virtual hostname on Amazon Route 53.

The DNSCMD.EXE command line utility is built into every Windows Server. If it's not already installed, you can add it from the "Server Manager" list. Select Features > Add Features > Remote Server Administration Tools > Role Administration Tools > DNS Server Tools.
