Question: Windows 2003 Server does not stream FLV videos Answer: With IIS 6.0, Microsoft changed the way streaming media is handled. Previous versions of IIS did not require any modification to stream Flash Video. Microsoft IIS 6.0, the default web server that ships with Windows 2003, requires a MIME type to recognize that FLV files are streamed media.
On the Windows 2003 server, open the Internet Information Services Manager.
Expand the Local Computer Server.
Right-click the local computer server and select Properties.
