i have a shared windows xp computer. i wasn't around one day and the next day i tried to log on to Facebook through chrome as usual and got the webpage unavailable message. I've tried IE and Firefox on this computer and none of them will get me to Facebook. I've tried to ping Facebook and the request timed out. I've tried turning off my firewall and I've tried turning off Norton. other computers on this same network can connect to Facebook just fine. i'm baffled. any ideas what the problem is?
