Specifying the files to create

Select which of the following types of files you want the wizard to create:

• Multicast information file (.nsc) and announcement file (.asx). Click to have the wizard create an announcement file (a file with an .asx file name extension) and a multicast information file (a file with an .nsc file name extension). The announcement file directs users to the location of the multicast information file. The multicast information file provides the player with the information it needs to connect to the multicast and render the stream. Select this option if this is the first time you have announced this publishing point.
• Automatically create a Web page. Select this checkbox to have the wizard create a Web page with an embedded player control that accesses the multicast stream.
• Multicast information file (.nsc). Click to have the wizard only create the multicast information file. This is useful if you have already announced the content but need to update the stream format or if you have reconfigured the WMS Multicast Data Writer plug-in on the Properties tab of the publishing point.
• Announcement file (.asx). Click to have the wizard only create the announcement file. This is useful if you have already created the .nsc file but need to update the location of the announcement file.

Note

• 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.
