I have a W2K8R2 SP1 (Datacenter Edition) Failover Cluster. Each node has 8 network interfaces: 4 External Virtual Networks connected to company network switches, 2 iSCSI interfaces (CSV) and 2 management interfaces on different subnets. NW3 (subnet 10, same subnet as the domain controller) is listed as a "Domain" network. NW4 (subnet 20) is listed as a "Public" network. With the exception of the External Virtual Networks, all cables are routed to a pair of HP V1810G 48 port gigabit switches trunked together. Each switch has 2 VLANs, one for iSCSI only and another for all others.
I was expecting NW4 to be listed as a domain network as well. Perhaps I have misconfigured something? Should I create another VLAN for subnet 20? Use more switches? Add a NIC to the domain controller on subnet 20? Maybe I need to register the subnet 20 IP addresses in DNS?
I am not a network engineer so I don't understand all of the intricacies involved. The network diagrams I have seen in researching this are line diagrams and not a physical representation of the network.
Thanks for your assistance, Vint
