FIX: Error message when you try to run an ASP.NET 2.0 Web application that includes Web services: "The file <FilePath> does not exist"

Article ID: 922345 - View products that this article applies to.

SYMPTOMS

When you try to run a Microsoft ASP.NET 2.0 Web application that includes Web services, you continuously receive the following error message:

The file <FilePath> does not exist

Note In this error message, <FilePath> is placeholder for the path of the .aspx file.

You continuously receive this error message until the Microsoft Internet Information Services (IIS) application pool that hosts the ASP.NET 2.0 Web application is recycled.

This problem may occur when you run the ASP.NET 2.0 Web application in a high-load environment.

CAUSE

This problem occurs because the code that generates the Web Services Description Language (WSDL) file may unregister any VirtualPathProviders class that is used by the ASP.NET 2.0 Web application. This problem may occur if more than one WSDL help request is in process. If the VirtualPathProviders classes are unregistered, any content that resides on the virtual path may be inaccessible.
