If you intend to deliver your live streaming content as a multicast stream you will need to modify 
one of the system Multicast templates and then use the Windows Media Services Multicast 
Announcement Wizard to create an announcement.  The announcement is a Windows Media 
metafile that provides the player with the information required to receive the streaming content.
