I just installed Hyper-V Server 2012 and first thing I get when logging in to the host is "No Active Network Adapter Found".

I know I have to use the following command:

pnputil –i –a <inf file>

I found the Realtek Network Driver for my MB for Windows 7 here: http://za.asus.com/Motherboards/AMD_AM3Plus/M5A97_PRO/#download

But there is not one for Windows 8 so I tried using the Win 7 one with PnPUtil, and I got:

Failed to install the driver on any of the devices on the system:   
No more data is available.

Does this really mean I can't use Hyper-V Server 2012 with my motherboard? This is hard to believe because I installed Windows Server 2012 directly (prior to installing Hyper-V Server 2012) on this same computer and I had internet access on that server without even configuring any drivers.


Ok so I went to PowerShell from cmd and typed

Get-NetIPConfiguration

And it said the name of my driver (Realtek) and "Disconnected". I switched the Ethernet wire from my primary computer with my server and everything was fixed. Interestingly, my primary computer connects to the internet just fine with the wire that was previously in the server, just with much slower speed.

Does anyone know what could be the difference between these 2 Ethernet wires?
