CAUSE

This problem may occur if the Web.config file is located in the root of the default Web site. The root is typically C:\Inetpub\Wwwroot.

The Remote Web Workplace inherits the information in the Web.config file from the root of the default Web site. If those settings are incompatible, the Remote Web Workplace may fail.

RESOLUTION

To resolve this problem, you must move the application that has been installed in the default Web site to another Web site or into a virtual directory. If you are no longer using the application, remove the Web.config file from the C:\Inetpub\Wwwroot folder. By default, the C:\Inetpub\Wwwroot folder does not contain the Web.config file on a Windows Small Business Server 2003-based computer.

Note Do not install any applications that reference ASP.NET on the companyweb Web site. If you do this, you may break the Microsoft Windows SharePoint Services Web site.

STATUS

This behavior is by design.

MORE INFORMATION

This error occurs when you are running the following software versions:
  • Version 1.1.4322.573 of the Microsoft .NET Framework
  • Version 1.1.4322.573 of Microsoft ASP.NET

How to turn off error reporting

  1. Open the Web.config file in the C:\Inetpub\Remote folder.
  2. Replace <customErrors mode="On" defaultRedirect="Error.aspx" /> with <customErrors mode="Off" />.

    Note "Off" is case sensitive.
  3. Save and then close the Web.config file.
  4. Click Start, click Run, type iisreset, and then click OK.
