I have removed viruses & spyware from a customers pc and now the network card will not obtain an ip address. After testing windows tcp/ip components, I finally decided to try another network card. It installed and gets an ip address just fine. The original network card was working just fine before the spyware so I don't believe the card is bad. I have went through and uninstalled the individual drivers for the network card and all related applications. I have downloaded the driver for the original card and reinstalled it. I still can't get it to take an IP address. Any ideas what to try next? Of course reinstalling the OS may fix it but I would prefer to find a way to fix it without taking that extreme option.
