The Windows Media server components and Microsoft Internet Information Services (IIS) can coexist on a computer when you use their default values as follows:
The Windows Media Unicast service binds to port 1755.To stream content through HTTP, the Windows Media Unicast or Windows Media Station service must have an IP address available on port 80. To do this, you must configure IIS so that is does not automatically bind to port 80 on all IP addresses. With IIS version 4.0 or later, you can specify an IP address that IIS can use when it binds to port 80 to serve HTTP streams. The Windows Media Unicast or Windows Media Station service can then use another available IP address to stream ASF content through HTTP. To enable HTTP streaming for the Windows Media Unicast or Windows Media Station service, Web sites running under IIS 4.0 or later cannot be configured to use all unassigned IP addresses.
The Windows Media Station service binds to port 7007.
IIS binds to port 80.
To use HTTP streaming when the Windows Media server components and IIS 5.0 are installed on the same computer, at least two IP addresses bound to your network card are required.
