Hi,

I have a three tier application. The presentation layer is done with WinForms, business layer is done as remoting server hosted in IIS (HTTP channel with binary serialization) and data layer is on SQL Server database.

My virtual application (IIS on WinXP Professional) is set to use Windows authentication.

My web.config contains:
        <authentication mode="Windows" />
        <identity impersonate="true" />

My client code contains:
    HttpClientChannel channel = new HttpClientChannel("tstServer", new BinaryClientFormatterSinkProvider());
    ChannelServices.RegisterChannel(channel);
    RemotingConfiguration.RegisterWellKnownClientType(typeof(TestServer), "http://localhost/TestApp/TestServer.rem");
    
    TestServer server = new TestServer();
    IDictionary channelProperties;
    channelProperties = ChannelServices.GetChannelSinkProperties(facade);
    channelProperties ["credentials"] = System.Net.CredentialCache.DefaultCredentials;
    
    server.Method1();
    server.Method2();
    ...

The application seems to work fine but the performance is not good. When I look in IIS log file I can see the following lines:

    09:21:42 10.32.161.115 POST /TestApp/TestServer.rem 200 2257 753 1773

Why do I still have 401 - 200. I thought I would have 401 and then just 200s. What is wrong with my code? Can I get rid of the 401s?

Thank you very much for any help or suggestion.

Regards,
Dave.
