Change the port Windows Media Services uses for HTTP streaming
To change the port Windows Media Services uses for HTTP streaming
Click the server for which you want to change the port allocated for HTTP streaming.
In the details pane, click the Properties tab.
In Category, click Control protocol.
In Plug-in, click WMS HTTP Server Control Protocol, and then click Properties.
If you have more than one IP address available on your server, in IP address, click Allow selected IP addresses to use this protocol, and then click the specific IP addresses you want to use from the list.
In Port selection, click Use other port, and then type the port number you want to use in the space provided. HTTP port numbers can range from 1 to 65535.
Click OK to apply the change.
In the details pane, in Plug-in, click WMS HTTP Server Control Protocol. Click Enable to make the HTTP protocol available for streaming content from your server.
Windows Media Services tries to use port 80 by default, but Web servers frequently reserve that port. To avoid port conflict, use a port other than 80 for HTTP streaming. If you do not use the default port, the URL that a player uses to connect to the publishing point must include the new port number. For example, if you change the HTTP port to port 1450, the connection URL would be http://server:1450/publishing_point.
To provide more than one port 80 on your server, you can install additional network adapters, or you can use the networking features of the operating system to add IP addresses to a single network adapter. After creating additional IP address/port 80 combinations, you must configure Windows Media Services and your Web server to use separate ports.
