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.


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.

To work around this problem, recycle the IIS application pool that hosts the ASP.NET 2.0 Web application to register the VirtualPathProviders classes again. To do this, follow these steps:
  1. Click Start, click Run, type inetmgr, and then click OK.
  2. Expand <Server Name>, and then expand Application Pools.

    Note <Server Name> is a placeholder for the name of the computer on which you want to recycle the IIS application pool.
  3. Right-click the IIS application pool that you want to recycle, and then click Recycle.
  4. Right-click <Server Name>.
  5. Click All Tasks, and then click Restart IIS.
  6. Click OK.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.


This hotfix becomes effective the next time that the IIS application pool is recycled.
