Losing connection after Reboot in XP

Hi, I am using windows XP and I have just reformatted my HDD after installing a new motherboard. However, I am having trouble with my ethernet connection. I have dsl and I am using a built in ethernet port. After I reboot my computer, I lose my connection. I can easily fix it by setting up a home or small office network. However, every time I reboot I must re-setup that network.

 

something may have gone awry with your installation of XP after the reformat. I would re-install, then make sure you download the latest drivers for the NIC from the mfr's web site, then go to Windows Update for patches and service packs. Did it work OK before the re-install? Same NIC?
