Netgear GA311 Gigabit NIC 10/100/1000 does not offer drivers to support Microsoft Windows 2003
Although I ran across this article that inspired me below, I physically verified the chip on the card. The Netgear GA311 REV.A1 uses Realtek’s RTL8169S-32 chipset. I have tested this driver on this card on a Windows 2003 server without any problem. The driver is available as a Windows XP driver (32-bit).
