Why is it that the simplest question always receives irrelevant answers and boiled waffles?
The link we are trying to reach is:
http://www.microsoft.com/windows/using/tools/igd/default.mspx
The error message: HTTP 404
with default redirect to http://windows.microsoft.com/en-IE/windows/how-to#2TC=windows8
So you see my friend, some smart web designer removed the link to a very useful piece of software.
If you never saw that tool (very possible scenario, we cannot know it all), can you ask your NW techies, INFOSEC, Productivity Centre, et. al. to find it in a backup and restore the download link?
Much Obliged :)
