Windows Media Services cannot bind to ports in your firewall that are being used by other services. You can avoid port conflicts between the Windows Media Services service and other services by assigning each service to a different port. You can install multiple network interface cards and assign IP addresses for the Windows Media Services service and other services to different cards, enabling each service to use the same port with a unique IP address. You can also configure the Windows Media Services service and other services to bind to separate IP address/port combinations on a single network interface card.
