I have a Dell Dimension 8100 running windows XP Pro. I can't seem to access certain website. The only 2 I have noticed are http://www.babycenter.com and http://www.gamefaqs.com. Evertime I try, a screen pops up that says DNS search error and that the websites could not be found. My other computer accesses the websites just fine. I have had this probles for about 1 month. Can anybody help me?
