I reloaded Win XP ( formatted drive too). Install went smooth. I can not get a IP Address from my ISP. ipconfig /all shows no addresses. I buillt a new Internet connection with no joy.
In Device Manager the NIC is fine, no yellow exclamation point and it says it is working fine.
But... I do have the Yellow Question mark on my Ethernet Controller.
Is the Ethernet controller software for the motherboard?
Thanks,
D.

If your Internet cable plugs into the motherboard, you have an on-board Ethernet and need to install motherboard drivers. If it plugs into a card that is plugged into your motherboard, it needs a separate driver. If you do not have a CD that came with the card, go on-line and find the correct driver, download, copy and install in your PC.
While the yellow exclamation mark is there, you will never get on-line.

Thanks Bob_180_Bob. I found the Intel driver needed on the web, installed it and it works great now. My backup that I did prior to the reload had a virus which i backed up. Now my machine is lean, mean and clean.
Thanks again.
