The Web.config file is missing

Symptoms

The Upgrade.log file contains an error that resembles the following:

[AssemblyReferenceFixUp] [3.0.4.0] [ERROR] [10/18/2007 11:47:40 AM]: Application Web Config for this IIS site (944564711) could not be found at \wwwroot\wss\VirtualDirectories\5003\web.config.

Cause

This behavior occurs when the Web.config file has been deleted or moved.

Resolution

To resolve this problem, make sure that the Web.config file is located in the Wwwroot\Wss\VirtualDirectories\xxxx folder before you run the SharePoint Products and Technologies Configuration Wizard.

Note xxxx represents the virtual server physical location for the SharePoint Web application. In IIS, the virtual server physical location is listed next to Local path on the Home Directory tab in the virtual server properties dialog box.
