Looks like the last MS-patch for Internet Explorer (MS04-004) wasn't quite what it should have been.
Microsoft on Thursday released a patch of the MS04-004 update that fixes Microsoft Extensible Markup Language (MSXML) functionality so that it can work properly with the changes made with the last patch...
There are three different versions available:
Service Pack2
Service Pack3
Service Pack4
Happy patching of the patch!
