I solved my own problem, I had to modify the driver, but I got it. I used this link:
Thank you for contacting the Intel® Communities.
I am glad to hear that you were able to get the NIC to work using a server OS.
I would also like to bring up the following, NUC were intended for "desktop" use, not so much server solutions, which may have been affecting the communication of the OS and the component.
If you encounter with any new or additional inquiries about any Intel® product, do not hesitate to contact the Intel® Communities.
Thanx for following up and I see that you have followed up on a bunch of peoples questions which is way cool.
As to OS being supported or not supported, Intel actually removed the ability to even get the driver installed on the NUC, I had to hack the driver just to get it to install. Why would they intentionally make it so that a driver will not work? The Driver is specifically written to only work on Windows 7/8/8,1/10 (even though WHS2011 is based on the same code as Win7). If the driver sees anything but those OS's it rolls itself back.
So you may not support, but at the same did Intel has REMOVED the ability to even try.
I am perhaps a bit late to this conversation (I see that there is an answer already).
By any chance did you try the following driver Download Network Adapter Driver for Windows Server 2008 R2*?
I believe the NUC you have uses and Intel I218-v Gigabit Ethernet controller so this driver should work.
No that is not how I did it but I do thank you for the link and information, its always cool to learn another way to solve these problems.
