Re: ET Dual Port Server Adapter And 2012R2

Hi snapmick,

Thank you for contacting Intel. 

The Intel® Gigabit ET Dual Port Server Adapter (E1G42ET) has In-box support only, no full support.  In box driver means the driver and software are not planned for this adapter model.  Please refer to our website for Intel® Ethernet Adapters with driver support for Windows Server 2012 R2*:

Hope this is helpful.

Sincerely, 
Sandy
