title: The request failed with HTTP status 400: Bad Request ( The data is invalid. ): Code base Works on one machine but not another
body: <p>This will probably be an environmental issue but I'm stumped as where to start.</p>
  
  <p>I'm attempting to call a a webservice on an external server in an asp.net web app while debugging in VS2008. The <strong>exact same code/project</strong> works on one machine calling the server but on another machine (my new one) it fails with the 400 Bad request (data is invalid) error.</p>
  
  <p>Both machines are running Windows 7. What should I be looking for as differences in the two machines that could be contributing to this problem?</p>
  
  <p><strong>Edit</strong> Deleting the webreference in the project and re-creating the webreference had no effect</p>
  
  <p><strong>Update</strong></p>
  
  <p>I went to use Fidler2 to inpect the request and response which resulted in the error going away. Things are beginning to point to an internet proxy issue.</p>
