I tried to repurpose one my my systems to run Windows Server 2003. System Specs are:
ASUS A8N-VM Motherboard
AMD X2-3800+ (s939) CPU
2x1GB DDR-333 RAM
120GB Hard Drive
I managed to get Server 2003 installed, but I would not connect to the internet, nor could it see any other systems on my network. I tried finding network drivers on the ASUS web site, but found none for that motherboard/OS.
It's definitely not a hardware issue, as after that failure, I re-installed and updated XP on the system without issue.
So now, I'm stuck trying to find a new motherboard that will accept a mainstream processor (Core2Quad or Phenom) as well as a Windows Server OS (going to try Server 2008 & Hyper-V next) and has all applicable drivers.
@ ZeCow - I have another system with a Gigabyte motherboard that supports Windows Server 2003, but I didn't want to repurpose that machine. I'll take another look at Gigabyte boards.
