windows update problem

I reformatted a few weeks ago, and since doing so I have not been able to get anything on Windows Update. It doesn't seem to be connecting to microsoft or something. Is there a fix for this anywhere?

What happens when you open a browser and go to http://windowsupdate.microsoft.com?

IE just sits there. I get nothing.

What OS?

XP

Does it end up redirecting to http://v5.windowsupdate.microsoft.com/v5consumer/default.aspx?ln=en-us??? Did you go there before and decline when it told you it needed to install the update component? First time there on this machine? Is there any HTML rendered in the browser at all?
