I go online and I find some random sites but that have a general theme (gaming) blocked. Like when I go to www.gamespy.com it comes up with this:401 website blocked by administratorI dont get it IM administrator.
check your blocked sites on your internet options
it might be your firewall?
i once had...a spyware issue....that blocked all sites that didn't have the domain www. it was kinda anoying. anyway, do a spyware check it could possibly fix your problem
