    Hello, I'm trying to call an asmx web service through a plugin.  I know asmx is old school but that's the web service that's been provided to me. Anyway, I need to programatically call the web service from the plugin.  My code is currently returning the following error:

    "The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Negotiate,NTLM'."

    Here's the code I'm using to try to call the asmx from the plugin:

            private void Execute()
            {
                string svcUrl = "http://mycompany.com/services/external-service.asmx";
                var svcClient = new mycompany.services.SwiVulnWriterSoapClient(Binding, new EndpointAddress(svcUrl));
                svcClient.ClientCredentials.Windows.AllowedImpersonationLevel = TokenImpersonationLevel.Impersonation;
                svcClient.Test()
            }

            private WSHttpBinding GetBinding()
            {
                return new WSHttpBinding
                {
                    Security = new WSHttpSecurity
                    {
                        Mode = SecurityMode.Message,
                        Transport = new HttpTransportSecurity
                        {
                            ClientCredentialType = HttpClientCredentialType.Windows
                        }
                    },
                    MaxReceivedMessageSize = 5242880
                };
            }

    Can you recommend steps to resolve or troubleshoot this error?

    One thing to check - is your code running in the sandbox or not ? If it's running in the snadbox, you won't be able to pass credentials
