SYMPTOMS
When a Microsoft .NET Framework 2.0-based application calls the HttpListenerRequest.GetClientCertificate method, the HttpListenerRequest.GetClientCertificate method may not retrieve the client certificate. This problem occurs if you use the HttpListener class to programmatically control the client certificate request. For example, you can configure the HttpListener class by using the Httpcfg.exe tool. This problem may occur after you run the Httpcfg.exe tool together with the /f option set to zero by using the following command:
httpcfg /f 0
