Flash Not Playing on IIS 7

The latest verion of IIS, 7, will not serve files with unknown extensions. Unfortunately, the .flv extension for Flash videos is one of the un-registered file extensions. This can cause serious grief when a video is not working and there is no error message.

You register a file type in the MIME section of IIS.

1. Open up IIS and right click the server listing.
2. Select Properties
3. Select File Types in the MIME Map section
4. Select New Type
5. Type ".flv" as the associated extension
6. Type "video/x-flv" as the content type
7. Select Ok
