ok, short question, my xp machine failed to connect manually to windows update today. i tried to use the "check for updates" under the "securIty" tab of "control panel" but when the usual internet explorer webpage opened it said it could not connect to the website. at that time the same browser was giving reliable access to other sites and chrome and firefox were both in working order. i disconnected my dongle(mobile broadband connection) and then plugged it back in after having closed and reopened the browsers. this time it was able to connect to www.update.microsoft.com/ and found nothing new that needed installing, can anyone suggest why the attempts to connect to that page failed but every other page worked fine at the time?
