I have a Dell PowerEdge 1950 rack-mount server with the latest BIOS (2.7.0) running 64-bit Server 2008 R2 Enterprise w/ SP1. I have installed the Hyper-V role and setup a VM running 64-bit Windows 7 Pro SP1. Everything went smoothly with the install except that I simply cannot get the Win 7 guest O/S to communicate on the network no matter what I try.
The host server has two Ethernet adapters, both of which are connected to my Gigabit switch. Initially each of them was setup with a static IP (in the Class A 10.0.0.0 range). After the installation of Hyper-V, there is also a third adapter showing up: "Local Area Connection 2 - Virtual Network" which is, of course, set to obtain its IP automatically.
In attempting to troubleshoot, I tried to use the "Legacy Adapter" on the VM - that did not work. I also tried setting one of my host machine's Ethernet adapters to obtain its IP automatically, leaving the other static. No good. Finally I disabled the second Ethernet adapter in the host machine entirely. Still no good.
I have also shut down the VM a couple of times and checked to see if there is anything I can adjust under "Settings". Aside from just removing and recreating the virtual network adapter, there doesn't seem to be much else I can do that is of any use.
Does anyone have any suggestions?
Any help would be greatly appreciated.
