Event ID 1007 — 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.

Resolve

Remove a duplicate binding

Web sites that have duplicate URL bindings will cause one of the Web sites to be disabled. Make sure that you do not try to register duplicate application URLs in the ApplicationHost.config or Web.config files. To resolve the duplication, determine which sites are using the same bindings. Then, modify the bindings as needed, and restart the site. You can do this by following the steps in A, B, and C.

A. Determine which sites are using the same bindings

To determine which sites are using the same bindings:

  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. Left-click the Sites folder. A list of the Web sites on the server appears on the right in Features View. The binding for each site is listed in the Binding column.
  5. Review the list of bindings and look for sites that have the same binding properties set. For example, look for two sites that both have a binding of *:80 (http).

B. Remove the duplicate binding

To remove the duplicate binding:

  1. In IIS Manager, in the Connections pane, select the Web site that you have to configure.
  2. In the Actions pane, click Bindings...
  3. To modify an existing binding, select the binding and click Edit.
  4. To add a new binding, click Add...
  5. After you have set the unique bindings for the site, click OK, then click Close.

C. Restart the Web site

To restart the Web site:

  1. In IIS Manager, in the Connections pane, select the Web site that you have to start.
  2. In the Actions pane, click Stop to stop the site.
  3. 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.
