I am running a single physical server -- a Dell PowerEdge T410 -- with Server 2008 R2 SP1 as the parent OS. I have 2 physical network cards configured with 2 static IP addresses (#.#.9.132 and 9.133 respectively). I want to use the first (9.132) as the NIC for the parent (NIC1) and the second (NIC2 = 9.133) for the 4 virtual machines I am going to run as guest (or child) OSes. I brought up the parent and updated the OS to current. I configured the 2 NICs (for IPv4 only) and had internet access on both. I then added the Hyper-V role and chose NIC2 as my virtual network (an external network). As expected, NIC2 now shows only the Microsoft Virtual Network Switch protocol enabled and I have a new "Virtual network" connection with the IP address of 9.133 -- all of this sounds reasonable and expected to me. The problem is that I don't get internet access on the virtual network connection -- every time I look at the properties, the DNS address is blank. I re-enter it and reboot and it still comes back with no DNS address.
It seems like I dealt with this once in the past, but I can't find the solution. What am I missing in this process?
TIA
