Note Image Notes

If the properties for this plug-in appear dimmed, you must stop the broadcast publishing point before making any modifications. After modifying this plug-in you must run the Multicast Announcement Wizard again to update the multicast information (.nsc) file with your changes before restarting the publishing point.
Windows Media Services is Internet Protocol version 6 (IPv6) enabled. IPv6 is the newest version of the Internet Protocol and was designed to accommodate the rapidly increasing demand for unique IP addresses. IPv6 increases the IP address size from 32 bits to 128 bits to support more levels of addressing hierarchy and a greater number of addressable nodes. Not all networks are configured to use IPv6, but Windows Media Services will automatically use it when it is available. For more information about IPv6, refer to the IPv6 page at the Microsoft Web site.
Multicast streaming and the WMS Multicast Data Writer plug-in are available only if Windows Media Services 9 Series is running on the following editions of the operating system: Windows Server 2003, Enterprise Edition and Windows Server 2003, Datacenter Edition. If you are running Windows Server 2003, Standard Edition, these features are not supported.
