A week or so ago I built a computer for my best friend in Arizona, using an Asus P4P800_Deluxe motherboard, which I found to be a pretty sweet motherboard. I hooked it up in my apartment to test it and tweak it, and get the Windows XP updates. My apartment comes with an ethernet connection in each room. When he recieved it in Arizona, an issue came up, but he asked me about it last night at 3AM and my troubleshooting skills aren't that great at that hour. When he plugs in his ethernet connection from a DSL modem, he gets link lights and the activity light blinks as it should, and his network connection is showing the LAN connection under network connections. However, when he starts Internet Explorer it can't find any website. The LAN connection shows packets sent but none are ever recieved. When I talk to him later today I am going to tell him to to get in the command prompt and do an ipconfig /release and /renew. If that doesn't solve the problem, what else can I check for or steps can I take?
