at this Microsoft KB web site;
see if you can reconfigure Windows Updates.
You say nothing happens. When you goto Start > Windows Update, does IE open up? If so, what happens then? Is a connection established to the internet? Does IE just sit there with a blank page?
When I go tothe windows xp update website. Nothing happens, it will not scan for updates. I don't get any error messages or anything. A few months ago I was receiving updates aon a regular bases. then I lose the update icon from the taskbar. I can still recive other downloads.
