I'm developing a WCF service that is RESTful and SOAP, now both of them needs to be with NTLM authentication.

I also want to expose a MEX endpoint so that others can easily reference the service and work with it.

Now when I set IIS to require windows authentication I can use the REST service and make calls to the service succesfully, but when I want to reference the service with SVCUTIL it throws an error that it requires to be anonymous.

Here's my web.config:

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
<bindings>
  <basicHttpBinding>
    <binding name="basicHttpBinding" maxReceivedMessageSize="214748563" maxBufferSize="214748563" maxBufferPoolSize="214748563">
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Ntlm">

      <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" />
    </behavior>
  </serviceBehaviors>
</behaviors>

Any help will be appreciated.
