Authentication failed when calling WCF service from ASP.NET

Question

Platform: VS 2008, .NET 3.5, C #, Oracle 11g

I created a WCF service that takes some data items and then inserts them into a database table and returns an integer. I also created a small ASP.NET web application to test this service. In the test web application, there is only a page with fields and a button, clicking this button actually calls the web service to insert data and return an integer value.

The steps I took:

• Create a WCF Service
• Publish WCF Service
• Generate proxy class (.cs) and app.config using svcutil
• Create an asp.net test application and add the proxy settings and configurations that you created in the previous step.
• Destroy test application

It works great when I deploy both WCF and a test web application on my computer - Windows XP, IIS 5.1. But, when I try to deploy them to a remote server, this will not work. When I try to use a service (deployed on a remote server - Windows 2003 server, IIS 6), I get the following error:

The request for the security token cannot be satisfied because the authentication failed.

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

Exception Details: System.ServiceModel.FaultException: The security token request could not be satisfied because authentication failed.

The following is a list of .config files:

May be related to wcf service security configuration, to be specific, Windows credential type requires a valid domain username and password.

Try providing the following attributes on clientide;

 proxy.ClientCredentials.Windows.ClientCredential.UserName = "UserName "; proxy.ClientCredentials.Windows.ClientCredential.Password = "Password "; proxy.ClientCredentials.Windows.ClientCredential.Domain = "Domain ";
