Internet Information Services (IIS) Web sites that use HTTP rely on several important IIS components for their availability. The Windows Process Activation Service (WAS), the World Wide Publishing Service (W3SVC), the HTTP service, all must be running correctly. In addition, a properly running application pool must be available for the Web site’s applications. If any of these components is not functioning, the Web site will not be available.
Stop and restart the site
On startup, WAS reads information from the ApplicationHost.config file. Part of the information that WAS reads is application configuration, such as enabled protocols and the application pools for the application. For applications to be configured correctly, there must be clear communication between WAS and the protocol for the application. Stopping and starting a site can reestablish this communication.
To stop and restart the site:
Click Start, click Control Panel, and then click Administrative Tools.
Right-click Internet Information Services (IIS) Manager and select Run as administrator.
In the IIS Manager Connections Pane, expand the computer name.
Select the Web site that has to be restarted.
In the Actions pane, click Stop to stop the site.
In the Actions pane, click Start to start the site.
