It would seem that the Windows/Microsoft Update site is a little bit broken. I noticed this recently and first thought that it was just a problem with Windows 2000. But it seems to be affecting Windows XP and Windows Server 2003 as well. All of the affected OS's give that same error message, with IE6 and Microsoft Update on Windows 2000, and IE8 and Microsoft Update on XP and Server 2003. Strangely enough, it would seem that the older (I think) Windows Update client still works, at least that is the case on my main computer running Windows XP x64. Has anyone else noticed this issue?
