It's been several days of replacing motherboards (Maximus IV Extreme), etc. without any success.
I've tried unsuccessfully for the last 24 hours to get a clean installation of WSE. The installation process fails because it cannot establish a network connection.
This is a completely new DIY system with the following components:
•ASUS Maximus V Extreme Motherboard, BIOS 1402 (or most current)
•750GB Primary HD (SATA)
•3 x 3TB Secondary HDs (SATA)
•1200W Power Supply
I've downloaded the current drivers (chipset, BIOS, LAN) from ASUS and Intel.
Oddly enough, the light actually illuminated when the Ethernet cable is connected to the computer, but Device Manager doesn't recognize the on-board Ethernet Controller.
Also not clear of any solutions are available.
At this point, I just need to get the driver issue resolved so I'm able to finish the Windows Server 2012 Essentials installation.
Oh and yes, power cord and Ethernet cables are in good working order.
