To prepare the Windows Media server for broadcasting a presentation

1. Open Windows Media Administrator.
2. Create the programs and streams to multicast the presentation and slides. You need to create the following items:
   • Two multicast file-transfer programs and two streams: one high bandwidth stream to transfer the slides into the browser cache before the presentation starts and one low bandwidth file-transfer stream to continue transferring slides during the presentation. See To create the multicast file-transfer program for Windows Media Presenter and To add a file transfer stream to a program for Windows Media Presenter for detailed step-by-step procedures.
   • One multicast station with a program and stream to multicast the ASF stream that contains the audio content, video content, and script commands. See To create a multicast station, program, and stream for Windows Media Presenter using the Station QuickStart wizard for a detailed step-by-step procedure.
3. Before the presentation is scheduled to begin, using Windows Media Administrator, start the programs that you set up. When you start the programs, the Windows Media server begins delivering information. Any user who goes to the initial Web page can begin receiving the presentation images.
