public void JACCS_Response(string date,string jaccs_id,string irn,string company_id,string xmlid)
       {
 
           string responseString = string.Empty;
 
// I am passing the following 4 parameters to the site.
 string REQ_STR = "SEND_DATETIME=" + date + "&KAMEITEN_BANGO=" + company_id + "&JACCS_DENPYO_BANGO=" + jaccs_id + "&DENPYO_BANGO=" + irn;
 
           try
           {
               HttpWebRequest webreq = (HttpWebRequest)WebRequest.Create(ConfigurationManager.AppSettings["someurl"].ToString());
 
//The app.config file contains the URL to which I post the data
 
               webreq.Method = "POST";
               //WebProxy myProxy = new WebProxy(ConfigurationManager.AppSettings["proxy"].ToString(), 80);
               WebProxy myProxy = new WebProxy("someproxy");
 
//The proxy is specified in the app.config
 
               //required only for local development
               myProxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
 
               //myProxy.Credentials = new NetworkCredential(ConfigurationManager.AppSettings["ProxyUID"].ToString(), ConfigurationManager.AppSettings["ProxyPwd"].ToString(), ConfigurationManager.AppSettings["ProxyDomain"].ToString());
 
               webreq.Proxy = myProxy;
 
 
//I specify the userid, password and the domain needed to access the external site
 webreq.Credentials = new NetworkCredential(ConfigurationManager.AppSettings["userid"].ToString(), ConfigurationManager.AppSettings["pwd"].ToString(), ConfigurationManager.AppSettings["domain"].ToString());
 
 
 byte[] byteArray = Encoding.GetEncoding("shift-jis").GetBytes(REQ_STR);
 
               webreq.ContentLength = byteArray.Length;
               webreq.ContentType = "application/x-www-form-urlencoded";
 
               webreq.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; GoogleT5; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.2; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)";
 
               using (Stream myStream = webreq.GetRequestStream())
               {
                   try
                   {
                       myStream.Write(byteArray, 0, byteArray.Length);
                       myStream.Flush();
                   }
                   catch (Exception e)
                   {
                       throw e;
                   }
               }
 
               // Get the response.
               HttpWebResponse response = (HttpWebResponse)webreq.GetResponse();
 
               StreamReader ResponseStream = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("shift-jis"));
               responseString = ResponseStream.ReadToEnd();
               ResponseStream.Close();
               response.Close();
           }
 
           catch (Exception ex)
           {
                throw ex;
           }
           }

But when I do the above, I get the error as ""The Remote server returned an error :(407) Proxy Authentication Required ".

Kindly help me out.
