Is physical NIC being recognized or is what I'm seeing a virtual NIC? hyper-v

I'm running Hyper-V 2008R2 server. Everything was working fine until I
decided to change the connection type from Internal Only to External. I
mention this, so when I tell you the problem you don't think it's a NIC
driver issue.
I used the MMC Hyper-V Managment plug-in to set the network connection
type to external and I selected "Allow management operating system to
share this network adapter". I also entered the Name as "Virtual Office
NIC". The action did not complete cleanly and I lost connectivity to the
Hyper-V server host.
When I go to the server and select item (8) Network Settings, I no longer
see the physical NIC, but I see the name "Virtual Office NIC".
Did I hose my physical NIC? Or did the Hyper-V Manager simply write a
string to the physical card's BIOS? That is, am what I seeing at the
server, a renamed physical NIC or a new virtual NIC.
Since I've disabled the physical NIC in the server's setup I assume I'm
seeing a virtualized NIC?
Assuming the physical NIC is still good, is there a way to fix this? I
don't see anyway to revert back to the Broadcom NIC from the host and all
connectivity to the box is toast.
