title: https request error on winXP
body: <p>i have a c# console application which consumes a webservice (a public webservice of a goverment). To do this, i added a Webservice Reference in my C#-Project, call the appropriate methods and everything works fine on. Except on one PC. </p>
  
  <p>It's a Windows XP SP2 PC, i installed .net framework 4 (which is the target framework of my application). When i call the same commandline-tool here i always get an error message. 100% percent the same tool with same parameters works fine on every other clients (Windows 7, Windows 8, Windows 8.1, even other Windows XP machines)!?!?!?</p>
  
  <p>Error message:</p>
  
  <blockquote>
    <p>Unhandled Exception:  System.ServiceModel.CommunicationException: An
    error occurred while making the HTTP request to
    <a href="https://adress.com/services/TheServiceWSI" rel="nofollow">https://adress.com/services/TheServiceWSI</a>. </p>
    
    <p>This could be due to the fact that the server certificate is not
    configured properly with HTTP.SYS in the HTTPS case.  This could also
    be caused by a mismatch of the security binding between the client and
    the server. 
    ---> System.Net.WebException:  The underlying connection was closed: An unexpected error occurred on a send. 
    ---> System.IO.IOException: Received an unexpected EOF or 0 bytes from the transport stream.</p>
  </blockquote>
  
  <p>I tried:</p>
  
  <ul>
  <li>deactivating firewall</li>
  <li>reinstalling .net framwork 4</li>
  <li>deactivating antvir software</li>
  <li>install all windows updates</li>
  </ul>
  
  <p>but no success...</p>
  
  <p>Has anyone an idea what could be the problem here?</p>
  
  <p>Thanks in advance!</p>
