I'm running windows xp professional, and I've been having trouble accessing web-based email services (hotmail, yahoomail, and also a private microsoft exchange server web interface) from my computer. I've tried using both firefox and internet explorer. When attempting to load my hotmail or yahoo inbox in ie, the page simply never loads. When I try in Firefox, I get an error message that reads "the document contains no data." I am able to access my inbox at the exchange server, but am unable to send emails.
I also can't access my online banking (fleet.com), and have had trouble posting to some tech support forums. I thought it was a problem with secure sites, but I am able to access some secure sites.
All of these services are fully available from a friend's computer running on the same internet connection, through the same router, so it's a problem specific to my machine. Any help?
