Weird problem... Within the last week or two, this machine has been having trouble getting to certain websites. For example, the machine has no problem getting to google, Microsoft, and a couple bulletin board sites. It cannot get to sites like usps.com, netflix.com, or here at OT. When I try to ping the sites it can't get to it says destination host unreachable. Other machines in the network are fine leading me to believe that it is something wrong with the machine. I chekced everything I could think of and found nothing wrong. The machine seems to be free of Spyware. It's running Windows XP SP2... Any ideas before I decide to format? Why would I be able to get to and ping certain sites, but others come back as destination unreachable?
