To install the Multicast and Advertisement Logging Agent

1. In Add or Remove Programs, click Add/Remove Windows Components.
2. In the Windows Components Wizard, select Windows Media Services and then click Details.
3. Select the Multicast and Advertisement Logging Agent check box and then click OK.

   The Wmsiislog.dll file is placed in the %systemdrive%\WMPub\WMIISlog directory, and the default multicast logging properties are set in the registry.

4. In Internet Information Services (IIS), create a virtual directory that references the %systemdrive%\WMPub\WMIISlog directory and then assign it read, run, and execute permissions. For more information about configuring IIS to use application extension, see IIS Help.

   You may now use the URL to the Wmsiislog.dll as the URL for any field that can use a logURL attribute, such as an announcement file, the Multicast Data Writer plug-in, a multicast information file, or clientData elements in a server-side playlist file. The logURL is specified as http://web_server_name/virtual_directory/wmsiislog.dll.

Notes

• The Multicast and Advertisement Logging Agent is dependent on Internet Information Services (IIS) version 6.0. If IIS version 6.0 is not installed on your server, selecting this component will also install IIS 6.0. However, removing this component does not remove IIS from your server. For more information about Internet Information Services, see IIS Help.
• It is recommended that you do not install the Multicast and Advertisement Logging Agent on the same computer that is running Windows Media Services. The Multicast and Advertisement Logging Agent uses Internet Information Services (IIS) to receive log files. By default, both Windows Media Services and IIS will attempt to bind to port 80, which causes a port conflict. If Windows Media Services and IIS are installed on the same computer, be sure each service has been allocated a unique HTTP port.
• If you change the default logging directory, you must grant the Multicast and Advertisement Logging Agent permissions to write to that directory. For the statistics to be successfully written to the log file, grant read and write permissions to the Network Service account and IWAM_HOSTNAME.
• 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.
