A friend's house had a lightning strike on a tree and the Verizon FIOS box near its base. This fried everything - box in their garage, modem/router and apparently the onboard nics in their two computers. The Verizon tech who reinstalled the boxes and put in new modem/router tested their connection with a laptop and connected to the internet normally, and suggested that their nics were fried too.
When I checked their pcs, I found that their nics were not working with both pcs showing a network cable was unplugged. I installed generic nics in both pcs. One a low end Dell, works fine without any tinkering in the bios - disabled the on board lan in Device Manager. But the other one a Compaq Evo D510 (a discarded corporate pc) won't connect to the internet. Both are running XP, ipconfig shows Compaq getting a valid IP and it pings the router fine, but cant ping other web addresses, it pulls the correct DNS address but times out. A few minutes after start up a limited connectivity icon pops up. It sees the other computers on the network, and data transfers between the pcs work fine, so does printing over the network.
Clicking on the limited connectivity icon, and then choosing repair - get a renewing IP address message - which shows up as failed with an 169.xxx.xxx.xxx ip address. Disabling the onboard lan does not make a difference. I havent gone into the bios and disabled the on board lan because I didnt know how to get into the bios<< does this have to be done.
I know that such power surges can do all kinds of damage, and the whole pc may be damaged/flaky. But it powers on normally, and the all programs, including games, run fine.
Any ideas and diagnostics to be run would be welcome.
