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 W3SVC
Stopping the W3SVC service will also stop any other services that depend on it. Thus, you may also have to start these other services.
To stop and restart W3SVC:
Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
At the command prompt, type net stop w3svc /y.
At the command prompt, type net start w3svc.
Start any other services that were stopped when W3SVC was shut down.
