Enabling multicast logging

You must specify the URL of the Web server location where you placed the Windows Media Internet Server Application Programming Interface (ISAPI) logging application (wmsiislog.dll). This DLL must be configured to be executed by Internet Information Services (IIS) in order for it to log information about clients that connect to your multicast.

• Yes, enable logging for this publishing point. Select this option to log information about your multicast streaming session.
• Logging URL. Type the logging URL in the text box. The logging URL is the URL of wmsiislog.dll. For example, if you have placed the DLL in the scripts directory of wwwroot, the URL would be http://IIS_server_name/scripts/wmsiislog.dll.

Notes

• The logging URL can also be modified in the Properties page of the WMS Multicast Data Writer plug-in. Changes made to the plug-in properties after creation of the multicast information file invalidate the announcement file and require that you run the announcement wizard again to update the file.
• 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.
