I am running windows xp on an AMD athlon 64 bit processor and gigabyte k8ns ultra motherboard with build in dual lan (nvidia chipset). Last night I encountered a very frustrating problem. My internet connection was working fine, then all of a sudden it stopped working. No matter what program i ran (AIM, mozilla, outlook express) i couldn't get on to the internet. I ran the ipconfig utility in the command prompt, and it showed that i was connected and was receiving a valid ip address from the network i'm on. I connected my friend's computer to the same jack that mine was connected to, and it worked fine. At this point i began to suspect a virus or spyware, so i scanned for both. Nothing was found. I used the command prompt to try to ping other computers, including myself but all i got was a message saying that whatever host i was trying to ping couldn't be found. I did an ip release and renew, and it took an extremely long time to get an ip address after the first few attempts at renewing it failed. I am convinced that is it something with my computer, but i have no idea. If someone could help me out i would greatly appreciate it. I'm also running norton internet security 2003. Thanks!
