SYMPTOMS
Impersonation may not work as expected when the following conditions are true:
 * A server is running Microsoft Internet Information Services (IIS) together with the Microsoft .NET Framework 1.1 Service Pack 1 (SP1). This server hosts an ASPX application in IIS.
 * IIS is installed on a second computer. The second computer hosts a Microsoft .NET remote object.
 * You call the .NET remote object that is hosted on the second computer from the ASPX application that is hosted on the server.

For example, a method may run under the ASPNET account instead of the IIS anonymous account.

This problem occurs even if the Web.config file contains the  and  settings.



CAUSE
This problem occurs when you make an asynchronous call to a remote method that has the OneWay attribute.
