Any help on this section of article would be great as I am currently stuck at this point. Trying to find some information.

"Install the windows operating systems on each VM and create a domain controller with a test domain on ClusterDC. Configure Public networking between the 3 VM's and join the 2 nodes to the domain. Configure the iSCSI network between the VM's and the NAS VM. Configure the heartbeat network between the cluster node VMs.

Ensure you set the network adapter bindings on the 2 cluster nodes. The Public NIC should have priority followed by the Heartbeat and then the iSCSI NIC."
