title: Receiving UDP on XP vs. Win7
body: <p>I am using a simple UDP Receiver code built in c++. I upgrade on of my machines to Windows 7 and this line is now getting held up because the UDP stream is not getting through to  the executable running:</p>
  
  <pre><code>  iResult = recv(sock, RxBuf, buffsize, 0);
  </code></pre>
  
  <p>The recv function is just held up. I have used wire shark to make sure the UDP stream is active and correct but don't know what the problem is.</p>
  
  <p>Any help would be appreciated.</p>
  
  <p>(the UDP stream is broadcasted)</p>
