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.

Add or edit site bindings

Ensure that the site has bindings with a valid port and IP address configured, and that the IP address and port configured for this Web site are not already being used by another site or entity. Only one Web site can be bound to a particular IP/port pairing at one time. After you add or edit bindings, you may have to restart the Web site, and, in some cases, the HTTP service.

Add or edit site bindings

To add or edit site bindings, follow these steps:

• Click Start, click Control Panel, and then click Administrative Tools.

• Right-click Internet Information Services (IIS) Manager and select Run as administrator.

• In the Connections Pane, select the Web site that you have to configure.

• In the Actions pane, click Bindings...

• To modify an existing binding, select the binding and click Edit.

• To add a new binding, click Add...

• After you have set the unique bindings for the site, click OK, then click Close.

Restart the site

If necessary, restart the site by following these steps:

• Click Start, click Control Panel, and then click Administrative Tools.

• Right-click Internet Information Services (IIS) Manager and select Run as administrator.

• In the Connections Pane, select the Web site that you have to configure.

• In the Actions pane, click Stop to stop the site.

• In the Actions pane, click Start to restart the site.

Stop and restart the HTTP service

In some cases, you may also have to stop and restart the HTTP service:

• Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

• Type net stop HTTP /y.

• Type net start w3svc. This will also start the HTTP service.

• Start any other services that were stopped when the HTTP service and W3SVC were shut down.
