Hello everyone, I have finished installing the Operating System: Windows Server 2012 Datacenter. Installation went smoothly without issue, and it was fairly fast installing it from my USB drive to the SSD.
The first thing I did was, of course, patches/updates. That completed again, without issue However, I did encounter an issue with the OS not discovering both of my LAN ports on my motherboard.
First, I would like to vent a little about why motherboard makers don’t use the same model of LAN port when they include more than one on the motherboard. I have no clue why. To me, it would make logical sense that they would use the same model, but at least in the case of the ASUS P9X79 WS motherboard they do not.
According to the ASUS webpage for this specific motherboard, it says (about the LAN ports) the following.
Built-in Dual Intel Server-Class Gigabit LAN
Dual Intel® hardware-accelerated LAN
For more reliable networking, the P9X79 WS features built-in dual Intel® Gigabit LAN. This leads to lower 71% CPU utilization , increasing throughput to achieve outstanding performance as well as better support for diverse operating systems.
Note that it refers to them as “server-class Gigabit LAN”. However, when you look at the specifications, it has an Intel® 82579V, 1 x Gigabit LAN Controller(s) and an Intel® 82574L, 1 x Gigabit LAN Controller(s).
Based on my research prior to purchasing this specific part, I recall reading from other users (that setup home labs and server OS’s), that (according to Intel) “The 82579V was never intended for server platforms and was not validated with any Windows Server operating system.” That being said, I remember reading about how some other users were able to modify the 82579V driver’s .inf file in order to make it “discover-able” and thus the driver to be installed on a server OS. Through much searching of the inter-web, I came across a site that explained this in detail (found here: http://www.ivobeerens.nl/2012/08/08/enable-the-intel-82579v-nic-in-windows-server-2012/). I followed these steps, and now have both the LAN ports present (one will be used for the Internet connection, and the other for the internal Hyper-V network).
For the purpose of information preservation, and easy reference, I have copy/pasted the steps below. For the original source, please see the link provided above.
Enable the Intel 82579V NIC in Windows Server 2012
After installing Windows Server 2012 on my homebrew server, the onboard Intel 82579V Gigabit NIC on the Asus P9X79 motherboard was not working. On the Asus site I found Windows 8 Intel drivers for the motherboard. After installing the drivers the NIC was still not working. To get the Intel 82579V NIC working in Windows Server 2012, I used the this forum thread as reference for this blog post.
Here are the steps:
- To be able to modify the drivers you need to run the the following commands:
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON
- Download the Intel drivers. In my case I used the Intel drivers Asus has available for the Asus P9X79 motherboard
- Save them to a map and extract them if needed
- Open the folder PRO1000
- Open the folder Winx64
- Open the folder NDIS63
- Open the e1c63x64.inf file, I used Notepad++ to edit the file
- In the [ControlFlags] section delete the 3 lines (1)
- Select and copy the five %E1503 lines (2)
- Paste the 5 lines in the [Intel.NTamd64.6.2] section below the %1502NC lines
- After the modifications the e1c63x64.inf file must look like this:
- Save the file
- Install the Intel drivers
- After the installation the Intel 82579V Gigabit NIC is recognized and enabled
- Enable the driver integrity checks and disable test signing again by using the following commands:
bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING OFF
Now you can use the Intel 82579V Gigabit NIC in Windows Server 2012.
