I am calling another one endpoint via code which is using 'ReportingService2010Soap' binding.

I have two client(WPF click once application) and one server where WCF deployed.

Client 1: Above code works fine without any issues.

Client 2: In page load I am calling both end points to verify both endpints are active. In above configuration I am getting this error and page itself not loading. Then I enabled WCF trace, in that calling BasicHttpBinding_AppSecurityService endpoint and throwing InnerException: The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate'. InnerException: The remote server returned an error: (401) Unauthorized. ReportingService2010Soap calls return result.

But If I remove this endpoint ReportingService2010Soap page loading without any issue.

So I am confusing where is error? either 1st endpoint or 2nd endpoint. If I remove 2nd endpoint application loading fine and If I enable application throws error in 1st endpoint.

I have enabled Windows Authentication and provider is 'Negotiate' in IIS.

Please check am I missing anything?
