TCPClient connect to IIS 6 with Integrated Windows Authentication

[mledbetter]

I've written a simple web stress tester application using TCPClient.
My code was working fine against our web server until our server admin changed IIS security setting by removing anonymous access and adding Integrated windows authentication.
Now I get 401 Unauthorized errors.
Here is the code that was working:

// Make non-secure HTTP Client connections.
        private string MakeTcpClientRequest()
        {
            String _url = this.SiteUrl;
            String _path = this.SitePath;
            String _domain = this.SiteDomain;
            IPAddress _ip = this.SiteIpAddress;
            Int32 _port = this.SitePort;
 
            String response = string.Empty;
 
            try
            {
                TcpClient client = new TcpClient();
                client.Connect(_domain, _port);
                client.LingerState = (new LingerOption(true, 0));
 
                //Console.WriteLine("Client Connected.");
                string crlf = Environment.NewLine;
 
                NetworkStream stream = client.GetStream();
 
                UTF8Encoding encoder = new UTF8Encoding();
                String pageString = "GET " + _path + " HTTP/1.1" + crlf;
                pageString += "Accept:*.*" + crlf;
                pageString += "HOST: " + _domain + ":" + _port + crlf + crlf;
 
                byte[] send = encoder.GetBytes(pageString);
 
                if (stream.CanWrite)
                {
                    stream.Write(send, 0, send.Length);
                    stream.Flush();
                }
                else
                {
                    throw new Exception("NetworkStream cannot write data.");
                }
 
                using (StreamReader reader = new StreamReader(stream, true))
                {
                    response = reader.ReadLine();
                }
 
                stream.Close();
                client.Close();
            }
            catch (SocketException ex)
            {
                //throw ex;
                Console.WriteLine(ex.ToString());
            }
            catch (Exception ex)
            {
                //throw ex;
                Console.WriteLine(ex.ToString());
            }
            // Set the response code:
            this._responseCode = (HttpStatusCode)SetResponseCode(response);
 
            return response;
        }
 

I'm not really sure where to go from here and was hoping someone could point me in the right direction.
Much thanks in advance.

There exists an HttpWebRequest object that would do this functionality for you.
You will need to supply credentials, either in the header via a string like you are using now, or in the HttpWebRequest object
