Hello Experts. A friend of mine has an issue with one of his systems. His business has approximately 15 computers connected to the network which is also connected to the internet. All of his systems are Windows 7 or Windows 8. One of his machines runs Windows XP. He recently had Centurylink upgrade his internet speed. All of his systems are fine, except the Windows XP system. The windows XP system is connected via wireless. Most of the systems are cabled, but others are wireless too. On the 'bad' system, It says it is connected to the internet and has a good signal. But if he tries to open IE it crashes. When I got on his system, I tried to ping the local network. That was fine. When I tried to ping outside the network (220.127.116.11) it could not find it. I tried other IP's too, same result. We have rebooted the system and the modem. Can someone please suggest how to debug this and then how to fix it? Or I guess, just fixing it would be great.
