I have a Vostro 200 which has an on board nic card. For some reason when I plug the ethernet cable into the computer it fails to get ANY ip. Meaning it doesn't even get the windows timeout IP. If I go to look at the IP address, it completely blank. So I tried uninstalling and reinstalling the drivers, that didn't work. I found a guide online about uninstalling TCP/IP and reinstalling it, that didn't work either. I tried doing a windows repair and that didn't work. So I just plugged in a new nic card and that one is having the same exact problem.
