title: Proxy Authentication Error while calling FedEx webservice
body: <p>I am trying to call the FedEx tracking webservice. Currently I am running the sample application provided by FedEx itself (Added my test account number and other details). When I run the application, I get the following error:</p>
  
  <p>The remote server returned an error: (407) Proxy Authentication Required.</p>
  
  <p>I am inside a proxy at my organization and I tried provided the proxy server details to the webservice client using the WebProxy class as:</p>
  
  <pre><code>trackService.Proxy = WebProxy.GetDefaultProxy();
  </code></pre>
  
  <p>and also by providing the proxy server details as:</p>
  
  <pre><code>trackService.Proxy = new WebProxy("IP",8080);
  </code></pre>
  
  <p>But I still keep getting the same error!! Could somebody help me how to resolve this problem?</p>
  
  <p>Thanks in advance,<br>
