How can I configure a serviceclient to consume MDS web service

Im working developing a Web Application who consumes MDS Web Service using C#; this Web Service is hosted in Server A using IIS. This Web App run perfectly when I'm working on local mode, I make request and the MDS Web Services response without problem. But, when I publish my Web app on another Server using IIS(Server B) I don´t have response from Web Service.

On Server B windows authentication is enabled for the Site where my App Web is hosted.

Server A, Server B and my machine belong to the same Intranet.

What I have tried:

This is my code in C#, with bindings and connections:

private static ServiceClient createMdsProxy(string mdsURL)  /
    {

        EndpointAddress pntFinalAddress = new EndpointAddress(new Uri(mdsURL), EndpointIdentity.CreateUpnIdentity("@etnas.conts.net"));
        WSHttpBinding wsBinding = new WSHttpBinding();
        wsBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;
        wsBinding.Security.Mode = SecurityMode.Message;

        wsBinding.Security.Message.ClientCredentialType = MessageCredentialType.Windows;
        wsBinding.Security.Message.NegotiateServiceCredential = true;           
        wsBinding.Security.Message.EstablishSecurityContext = true;

        wsBinding.MaxReceivedMessageSize = 2147483646;
        wsBinding.MaxBufferPoolSize = 2147483646;


        return new ServiceClient(wsBinding, pntFinalAddress);
    }

Within other method I call createMdsProxy method:

mdsproxy = createMdsProxy("http://arwdw20.etnas.conts.net:8001/service/Service.svc");
mdsProxy.ClientCredentials.Windows.ClientCredential.UserName = System.Threading.Thread.CurrentPrincipal.Identity.Name;

//.
//.Code to make the request using MDS Web Service Methods.
//.
EntityMembersGetResponse getResponse = mdsProxy.EntityMembersGet(getRequest);// Get the entity member information

The next code is Web.config Im using on client side.

<configuration>  <system.serviceModel>
<bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_IService">
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Windows"/>
      </security>
    </binding>
  </basicHttpBinding>
  <wsHttpBinding>
    <binding name="WSHttpBinding_IService"/>
  </wsHttpBinding>
</bindings>
<client>
  <endpoint address="http://arwdw20.etnas.conts.net:8001/service/Service.svc" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IService" contract="IService" name="WSHttpBinding_IService">
    <identity>
      <userPrincipalName value="DSSService@itnes.conts.net"/>
    </identity>
  </endpoint>
  <endpoint address="http://arwdw20.etnas.conts.net:8001/service/Service.svc/bhb" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IService" contract="IService" name="BasicHttpBinding_IService"/>
</client>  </system.serviceModel>  <system.web>    <compilation debug="true"/>  </system.web></configuration>

And This one is part of WSDL FILE from MDS Web Service:

<wsdl:service name="Service">
     <wsdl:port name="WSHttpBinding_IService" binding="tns:WSHttpBinding_IService">
          <soap12:address location="http://arwdw20.etnas.conts.net:8001/service/Service.svc" /> 
          <wsa10:EndpointReference>
            <wsa10:Address>http://arwdw20.etnas.conts.net:8001/service/Service.svc</wsa10:Address> 
               <Identity xmlns="http://schemas.xmlsoap.org/ws/2006/02/addressingidentity">
                  <Upn>DSSService@itnes.conts.net</Upn> 
               </Identity>
          </wsa10:EndpointReference>
     </wsdl:port>
     <wsdl:port name="BasicHttpBinding_IService" binding="tns:BasicHttpBinding_IService">
         <soap:address location="http://arwdw20.etnas.conts.net:8001/service/Service.svc/bhb" /> 
     </wsdl:port>
</wsdl:service>

I hope you can help me to solve this issue.
Thank you so much!
