Are you installing x86 or x64?
From what I have read it looks like all 64 bit system are not seeing this correctly. I looked at ASRock’s website and did not even find a driver for that. Best thing is to try the latest drivers from Intel. If that does not work then contact tech support and make sure to ask about Vista drivers. I have contacted a few companies and they all give me the run around when I tell them Windows Server 2008.
