I have an Acer Aspire One netbook (A0531h) that cannot access (or even ping) microsoft.com. I can access (and ping) any other site just fine. I just re-installed Windows XP Pro 5 mins ago (second time) so I know it's not infected with anything.
Ping request could not find host microsoft.com
It is using an Atheros AR5007EG wireless card.
What could be causing this?
