Event ID 1003 — IIS Web Site Availability

  • Article

Applies To: Windows Server 2008 R2

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.
