This will open the DNS Manager GUI. The File Replication service (FRS) does not replicate with a file share that is on a server cluster under a virtual server's computer object. The first is mostly used as DNS Server - the second as fallback. In a cluster with multiple subnets (such as a multi-site cluster) you may see something like the example below: In some respects, this architecture is great because you no longer need to use complex network magic to span a subnet across geographic differences.

Ensure that the network adapters associated with dependent IP address resources are configured with at least one accessible DNS server. I tried 2 things: DNS resolution in a multi-site server cluster. All servers must have the Failover Clustering feature installed. All servers must use logo’d hardware that has been certified and the collection of servers must pass all cluster validation tests. This problem with DNS also affects multi-site Hyper-V clusters. You can add Windows hosts to a custom cluster by editing the cluster and choosing the Windows option.. From the Global view, click Clusters..
