Windows Can't Display the Update Page

I've seen this a couple of times... Windows XP and you go to manually run Microsoft or Windows Update and it comes back to a screen saying: "The website has encountered a problem and cannot display the page you are trying to view. The options provided below might help you solve the problem." and it seems like you can't do anything about it. Microsoft does have a Knowledge Base article addressing it and it's worked for me every time. It seems that once you do the fix the problem disappears forever (in my experience). Here's the Microsoft article. There's an additional reference to a similar behaving problem here.
