Fortify DCOMs AppId permissions. Any changes should be thoroughly tested so objects continue to function under tightened security. - Open the Registry Editor. - Navigate to HKEY_LOCAL_MACHINE\Software\Classes\Appid. - Select the application that generated this vulnerability. - Set the permissions for standard (non-privileged) user accounts or groups to Read only.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
