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.
Set the application path for a site
A Web site must have a valid application path. If the application path is incorrect, the site will not start. Set a valid application path for the Web site, then restart the site.
Set a valid application path for the Web site
To set a valid application path for the Web site:
Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
Type cd %Windir%\system32\inetsrv\config
Type notepad ApplicationHost.config.
In Notepad, search for the sites section under system.applicationHost, and locate the Web site that is causing the error.
Correct the application path, or add the following to the site configuration so that it has a default path:
<virtualDirectory path="/" physicalPath="%SystemDrive%\inetpub\wwwroot" />
Restart the Web site
To restart the Web site:
Click Start, click Control Panel, and then click Administrative Tools.
Right-click Internet Information Services (IIS) Manager and select Run as administrator.
In the IIS Manager Connections Pane, expand the computer name.
Select the Web site that has to be restarted.
In the Actions pane, click Stop to stop the site.
In the Actions pane, click Start to start the site.
