If you use a Windows hosting, sometimes after embedding video into your webpage, uploading to a Microsoft Windows 2003 server and then viewing in a browser the player says that the “specified file is missing”. The SWF file (flash player) shows correctly, but the FLV video does not stream.
Microsoft Internet Information Server (IIS) 6.0, the default web server that ships with Windows 2003, requires a MIME type to recognize that FLV files are streamed media.
Log on the Windows 2003 server and run the Internet Information Services Manager.
Go Start > All Programs > Administrative Tools > Internet Information Services (IIS) Manager
Note: If you do not have access to the server, please send this guide to your hosting provider or administrative contact.
Right-click the local computer server and select Properties.
Then click the MIME Types… button
