Want to alter the default error pages displayed by IE ?
Download Resource Hacker (http://www.users.on.net/johnson/resourcehacker/) and open %SystemRoot%\system32\shdoclc.dll. In the resource fork (i.e. the folder in the tree view) marked “23″, all the HTML source for the various IE error messages is contained. Simply replace the HTTP_404.HTM resource code with your own source.
Nice eh
