WCF - changing endpoint address results in securityexception
My WCF Service uses wsHttpBinding and works fine from the client when the service is gerenated by the client using the default options as follows:

            RServiceClient R = new RServiceClient();

However, at some point I'll need to be able to specify the location of the service, presumably by changing the endpoint address as follows:

            RServiceClient R = new RServiceClient();
            R.Endpoint.Address = new EndpointAddress(new Uri "http://xxx.xxxx.xxx:80/RServer/RService.svc"));

However, when I do specify the exact endpoint, I get a SecurityNegotiationException:
System.ServiceModel.Security.SecurityNegotiationException was unhandled
  Message="The caller was not authenticated by the service."
  Source="mscorlib"....

The WCF service runs on IIS and has anonymous access enabled under IIS admin. Also, this error occurs when the client is run from the same machine as the service under an admin account - I havn't got to the scary part of running it over the net yet!

Any Ideas?
