How do I configure Windows Media Services and IIS to use the HTTP protocol on the same server?
If you set up Windows Media Services to stream content by using HTTP on a Web server that is running Internet Information Services (IIS), both services will try to bind to port 80. You can avoid this conflict by changing the port that Windows Media Services uses for HTTP streaming. As an alternative, you can create multiple IP addresses on a single network adapter and then assign separate port 80 addresses to these IP addresses. You must then configure Windows Media Services and IIS to bind to different IP address/port 80 combinations. For more information, see Using HTTP for Streaming and Downloading from the same computer.
