I'm having a major spin cycle installing drivers for the i219-V controller chip with Server 2012 R2. The correct driver appears to be Intel LAN Driver V20.2.3001.0 for Windows Win8.1 64bit.
ASUS doesn't "support" 2012 R2, so the ASUS installation application errors out as an unsupported operating system. The Intel application doesn't see the controller as an Intel product (I assume because it is new). The "Update Driver" function in WinServer device manager doesn't see the chip in the device database. Any suggestions?
