I got an old desktop I want to use as a file server. I installed windows server 2003 and it loads fine but the Ethernet drivers are not installed. I went to device manager and there is a bunch of yellow question marks in the ethernet adapter section. It says no drivers. I cant connect to the internet with that machine, I dont know the name of the intergrated NIC so how can I get deivers for it? Also when I plug the cable in the back it turns yellow instead of green. Any ideas ?
