Your network contains a server named Server1 that runs Windows Server 2008 R2. Server1 has the Streaming Media Services role and the Web Server (IIS) role installed.
Server1 hosts the company’s intranet Web site.
You need to configure Windows Media Services to stream content by using HTTP.
What should you do first?
A. Install the RPC over HTTP proxy server feature.
B. Configure a host header for the intranet Web site.
C. Configure the server to have an additional IP address.
D. Create a new virtual directory on the intranet Web site.
Correct Answer: C
Explanation/Reference:
Microsoft Windows Media Services (WMS) and Microsoft Internet Information Services (IIS) can coexist on a computer when you use their default values. By default, WMS does not enable the WMS HTTP Server Control Protocol plug-in. In this manner, IIS can safely bind to port 80 for delivery of Web-based content.
Sometimes it can be useful for WMS to use port 80 to deliver content. For example, if the majority of a content provider’s clients are behind a firewall, it can be better to use port 80 for delivery of streaming content, because most firewalls have port 80 opened.
With IIS 6.0, HTTP requests are handled by the Http.sys listener. By default, Http.sys will listen to all requests coming in on port 80 for all IP addresses bound to the computer (except for the loopback address: 127.0.0.1). For WMS to bind to use port 80 for streaming content, you must configure the Http.sys listener so that WMS can listen to the specified IP addresses. If you enable the HTTP Server Control Protocol plug- in without configuring the listener, you may receive the following error:
One usage of each socket address (protocol/network address/port) is permitted. Verify that other services (such as IIS) or applications are not attempting to use the same port and then try to enable the plug-in again.
Error Code: 0xC00D158B
MORE INFORMATION
For both IIS and WMS to use port 80, one of the following two conditions must be true:
One (1) network adapter has at least 2 IPs bound to the adapter.
Two (2) network adapters have at least 1 IP bound to each adapter.
