I have a Windows Server 2012 Failover Clustering Instance, hosting a SQL Server 2012 Enterprise Cluster, via NODE1 and NODE2.
I need to add a new read-only Replica to this cluster: NODE3, which is a Windows Server 2012 R2.
I've activated SQL Server AlwaysOn to both FCI NODE1 and Node2.
I've tried to add the new node, NODE3, to FCI cluster services, however I'm seeing this error
cluster node could not join the cluster because it failed to communicate over the network
What do I need do to add NODE3 as a read-only replica in FCI?
