WCFTestClient exception on deployed service

Question

I use the WCFTestClient that is provided with visual studio to test my service. The thing is that the tool is working for the service that is deployed in wisual studio with my aplication. But if I try to connect to a deployed instance on another machine I get the following exception. Has anyone solved this issue?

The service uses WindowsAutentication.

The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate oX0we6ADCgEBonQEcmBwBgkqhkiG9xIBAgIDAH5hMF+gAwIBBaEDAgEepBEYDzIwMTAxMDI3MDgzNTIxWqUFAgMCED6mAwIBKakLGwlCQVcuTE9DQUyqJzAloAMCAQOhHjAcGwRob3N0GxRsYmFpdGVzdDAxLmJhdy5sb2NhbA=='.

You can right click on the config file in wcftestclient, click copy Full path, open the path it in an editor and check that the security settings match the deployed service configuration
