i wrote a wcf service with wsDualHttpBinding

my web.config in Service is :

<?xml version="1.0"?>
    <compilation debug="true" strict="false" explicit="true" targetFramework="4.0" />
     <customErrors mode="Off"/>
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true" />
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false" />
      <service name="Chat_Server.Service_Chat">
        <endpoint binding="wsDualHttpBinding" bindingConfiguration="DuplexBinding" contract="Chat_Server.IService_Chat">
        <binding name="DuplexBinding">
          <reliableSession ordered="false"

            inactivityTimeout="00:02:00" />
          <security mode="Message">
            <message clientCredentialType="Windows" />
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    <modules runAllManagedModulesForAllRequests="true" />

and my web.config in Client is :
                <binding name="WSDualHttpBinding_IService_Chat" />
            <endpoint address="http://localhost:1462/Service_Chat.svc" binding="wsDualHttpBinding"

                bindingConfiguration="WSDualHttpBinding_IService_Chat" contract="ServiceReference_Chat.IService_Chat"

                    <userPrincipalName value="mycomputername" />

and this is my code in client for Open Service :
        'Open Service
        Dim context As New InstanceContext(New CallBack_Chat())
        Dim m_ServiceContext As Service_ChatClient

        Dim binding As New WSDualHttpBinding()
        binding.Name = "WSDualHttpBinding_IService_Chat"
        binding.ReliableSession.Ordered = True
        binding.TextEncoding = Text.Encoding.UTF8
        binding.ReliableSession.InactivityTimeout = New TimeSpan(0, 1, 0)
        binding.ReceiveTimeout = New TimeSpan(0, 1, 0)
        binding.SendTimeout = New TimeSpan(0, 0, 30)
        m_ServiceContext = New Service_ChatClient(context, "WSDualHttpBinding_IService_Chat")
        m_ServiceContext.Endpoint.Binding = binding


but when i run my project it has error (The caller was not authenticated by the service. When i call my service)

where is my problem?

thank you.

Try adding windows credentials to service client via code like:
m_ServiceContext.ClientCredentials.Windows.ClientCredential.UserName = "serverusername";
m_ServiceContext.ClientCredentials.Windows.ClientCredential.Password = "serverpassword";
m_ServiceContext.ClientCredentials.Windows.ClientCredential.Domain = "serverdomain";

See if that helps.
