You can add a <REF> tag to the announcement file to specify the content to be played before and after the multicast stream. If a client tries to connect to a multicast stream using the following example announcement file, the client will connect first to a unicast server to view an introductory file, and then will connect to the multicast stream. After the multicast stream has ended, the client will be directed to a concluding file at the end of the broadcast.

Multicast streaming is not available if Windows Media Services is installed on some Windows Server 2008 and Windows Server 2008 R2 operating systems. For more information, see Decide which version of Windows Server is right for you.
