Event ID 5151 — 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.

Event Details

Product: Internet Information Services
ID: 5151
Source: Microsoft-Windows-WAS
Version: 7.5
Symbolic Name: WAS_EVENT_FAILED_TO_SEND_APP_UNCONFIG_TO_PROTOCOL
Message: Windows Process Activation Service (WAS) did not send a request to protocol %1 to remove configuration for application %3 in virtual site %2. WAS will assume that the protocol is disabled. To guarantee the state, start and stop the virtual site. The data field contains the error number.

Resolve

Stop and restart a virtual 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 perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To stop and restart the virtual site:

  1. Click Start, click Control Panel, and then click Administrative Tools.
  2. Right-click Internet Information Services (IIS) Manager and select Run as administrator.
  3. In the IIS Manager Connections Pane, expand the computer name.
  4. Expand Sites.
  5. Select the Web site that has to be restarted.
  6. In the Actions pane, click Stop to stop the site.
  7. In the Actions pane, click Start to start the site.

Verify

To verify that a Web site is started, you can use either IIS Manager or the appcmd command line utility.

To perform these procedures, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To verify that the Web site is started by using the appcmd command line utility:

  1. Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
  2. Change the directory to %SystemDrive%\Windows\System32\inetsrv.
  3. Run the following command: appcmd.exe list site -site.name:"Site Name". If the Web site is started, the output will resemble the following:

        SITE "Default Web Site" (id:1,bindings:http/*:80:,state:Started)

To verify that the Web site is started by using IIS Manager:

  1. Click Start, click Control Panel, and then click Administrative Tools.
  2. Right-click Internet Information Services (IIS) Manager and select Run as administrator.
  3. In the Connections pane, expand the computer name.
  4. In the Connections pane, click the Sites node.
  5. In Features View, look for the Web site name. The Web site status will be indicated under the Status column. If the Web site is started and is using the HTTP protocol, Started(http) will appear.
