SYMPTOMS
You are running Microsoft Windows Small Business Server 2003. When you try to use the Remote Web Workplace or another subweb that is using Microsoft ASP.NET under the default Web site, you may receive an error message that is similar to the following:

Server Error in '/Remote' Application.

Assume that you turn off the friendly custom error by modifying the C:\Inetpub\Remote\Web.config file after you receive this error. If you then try to access a remote Web workplace or a subweb under the default Web site, you receive an error message that is similar to the following:

Server Error in '/Remote' Application.

Debugging is not supported under current trust level settings.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

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  with .

Note &quot;Off&quot; is case sensitive.
 * 1) Save and then close the Web.config file.
 * 2) Click Start, click Run, type iisreset, and then click OK.
