A server-side database availability group administrative operation failed. Error The operation failed. CreateCluster errors may result from incorrectly configured static addresses

Recently , we were working with one of our customer to build the Exchange 2019 DAG. When we add the 2 Exchange Nodes to the DAG , the process got failed with the error “A server-side database availability group administrative operation failed. Error The operation failed. CreateCluster errors may result from incorrectly configured static addresses – Error: Windows Failover Clustering isn’t installed on ‘xxxxxx’.. [Server: xxxxxxxxx] – Restart the server to complete the failover cluster installation also check for the duplicate mac , incorrect IP address, if it is a VM make sure you have done sysprep.”

However , we were pretty sure that the servers were created using a fresh installation instead of syprepped images. Also , we noticed that the Server Manager on both the servers were displaying a message ” Restart is Pending”.

Therefore , we simply restarted the server , and thereafter we were able to add the 2 exchange servers to the DAG.
