Web sites and Web applications depend on the availability of Internet Information Services (IIS) application pools. IIS application pools in turn depend on the Windows Process Activation Service (WAS). If WAS is not running or errors occur during the startup or shutdown of an application pool, Web sites and Web applications may not be available.

Resolve

Configure the globalModules section in ApplicationHost.config

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

To configure the globalModules section in ApplicationHost.config:

  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. Type cd %Windir%\system32\inetsrv\.

    A directory with the backup name that you specify will be created under the %Windir%\system32\inetsrv\backup directory. If you do not specify a name, appcmd will generate a directory name automatically using the current date and time.

  4. Type cd %Windir%\system32\inetsrv\config
  5. Type notepad ApplicationHost.config
  6. In notepad, search for the globalModules section under the system.webServer section.
