WCF-Problembehandlung aus ASP.NET Client — Hilfe!!!

Ich versuche eine Methode aufzurufen, die in meinem Dienst, wie unten, aus einer ASP.NET -Anwendung.

public bool ValidateUser(string username, string password)
{
    try
    {
        //String CurrentLoggedInWindowsUserName = WindowsIdentity.GetCurrent().Name;
        ////primary identity of the call
        //String CurrentServiceSecurityContextPrimaryIdentityName = 
        //  ServiceSecurityContext.Current.PrimaryIdentity.Name;
        //
    }
    catch (Exception ex)
    {
        FaultExceptionFactory fct = new FaultExceptionFactory();
        throw new FaultException<CustomFaultException>(fct.CreateFaultException(ex));
    }
    return false;
}

Die Config für den client Ende meines Dienstes ist wie folgt

<binding name="WSHttpBinding_IMembershipService" closeTimeout="00:01:00"
     openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
     bypassProxyOnLocal="false" transactionFlow="false"
     hostNameComparisonMode="StrongWildcard"
     maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text"
     textEncoding="utf-8" useDefaultWebProxy="false" allowCookies="false">
    <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
       maxBytesPerRead="4096" maxNameTableCharCount="16384" />
    <reliableSession ordered="true" inactivityTimeout="00:10:00"
       enabled="false" />
    <security mode="Message">
        <transport clientCredentialType="Windows" proxyCredentialType="None"
         realm="" />
        <message clientCredentialType="Windows" negotiateServiceCredential="true"
         algorithmSuite="Default" establishSecurityContext="true" />
    </security>
</binding>

Problem, das ich behalten habe, ist, wenn ich es nennen; ich bekomme die folgende exception message.

Server Error in '/' Application.

   Controls.Membership.accountLogin.ValidateUserCredentials(String UserName, 
            String Password) in C:\ Petition.WebClient\Controls\
                               Membership\accountLogin.ascx.cs:49
   Controls.Membership.accountLogin.Login1_Authenticate(Object sender, 
             AuthenticateEventArgs e) in C:\ WebClient\ Controls\Membership
                                      \accountLogin.ascx.cs:55

Ich bin mir nicht ganz sicher, warum ich immer diese. Nur für den Fall, hier ist, wie nenne ich meinen Dienst vom client

private bool ValidateUserCredentials(string UserName, string Password)
{
    bool boolReturnValue = false;

    using(Members.MembershipServiceClient client =
        new Controls.Members.MembershipServiceClient())
    {
        try
        {
            boolReturnValue = client.ValidateUser(UserName, Password);
        }
        catch (FaultException<CustomFaultException> ex)
        {
          throw ex;
        }
    }

    return boolReturnValue;
} 

Jemand eine Idee, was ich tun müssen, in diesem Fall?
