WCFTestClient exception in deployed service

Question

I use WCFTestClient, which is provided with a visual studio to test my service. The fact is that this tool works for a service that is deployed to wisual studio using my application. But if I try to connect to the deployed instance on another computer, I get the following exception. Has anyone solved this problem?

The service is using 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 configuration file in wcftestclient, click on the copy of the full path, open the path in the editor and check if the security settings match the deployed service configuration
