One of my clients has an intranet-only website that contains many links to files on the local network, in the form of <a href="file://localfileserver/importantdocument.doc">Link</a>. However, none of the links seem to work anymore in IE9. I know all the other browsers refuse to allow linking to local files from pages fetched over HTTP, is this the case in the newest version of IE as well?
All the links still work fine on IE8.
Please see this post. The change here was also made to IE8, so I'm guessing that the Zone settings you have are configured differently between the IE8 and IE9 machines.
