Might be the same issue as this previuos question: WCF Proxy but not sure...

I have an HTTPS service connfigured to use transport security and, I hope, Windows credentials. The service is only accessed internally (i.e. within the intranet). The configuration is as follows:

<configuration>
  <system.serviceModel>
    <services>
      <service name="WCFTest.CalculatorService" behaviorConfiguration="WCFTest.CalculatorBehavior">
        <host>
          <baseAddresses>
            <add baseAddress = "https://localhost:8000/WCFTest/CalculatorService/" />
          </baseAddresses>
        </host>
        <endpoint address ="basicHttpEP" binding="basicHttpBinding" contract="WCFTest.ICalculatorService" bindingConfiguration="basicHttpBindingConfig"/>    
        <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange"/>
      </service>
    </services>
    <bindings>
      <basicHttpBinding>
        <binding name="basicHttpBindingConfig">
          <security mode="Transport">
            <transport clientCredentialType = "Windows"/>
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="WCFTest.CalculatorBehavior">          
          <serviceAuthorization impersonateCallerForAllOperations="false"  principalPermissionMode="UseWindowsGroups" />
          <serviceCredentials >
            <windowsAuthentication allowAnonymousLogons="false" includeWindowsGroups="true" />
          </serviceCredentials>
          <serviceMetadata httpsGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

When I run the service I can't see the service in IE. I get a "this page can not be displayed" error. If I try and create a client in VS2008 via the "add service reference" wizard I get this error:

There was an error downloading 'https://localhost:8000/WCFTest/CalculatorService/'. There was an error downloading 'https://localhost:8000/WCFTest/CalculatorService/'. The underlying connection was closed: An unexpected error occurred on a send. Authentication failed because the remote party has closed the transport stream. Metadata contains a reference that cannot be resolved: 'https://localhost:8000/WCFTest/CalculatorService/'. An error occurred while making the HTTP request to https://localhost:8000/WCFTest/CalculatorService/. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server. The underlying connection was closed: An unexpected error occurred on a send. Authentication failed because the remote party has closed the transport stream. If the service is defined in the current solution, try building the solution and adding the service reference again.

I think I'm missing some fundamental basics here. Do I need to set up some certificates? Or should it all just work as it seems to do when I use NetTcpBinding?

Thanks
