title: Azure Service Bus Sample "No connection could be made because the target machine actively refused it"
body: <p>I'm trying  to run the Azure Service Sample (MessagingWithQueue) which I downloaded from <a href="http://www.microsoft.com/download/en/details.aspx?id=17691" rel="nofollow">http://www.microsoft.com/download/en/details.aspx?id=17691</a>.</p>
  
  <p>However, I've been getting this error message:</p>
  
  <blockquote>
    <p>Could not connect to net.tcp://xxxx.servicebus.windows.net:9354/. The
    connection attempt lasted for a time span of 00:00:00.0615234. TCP
    error code 10061: No connection could be made because the target
    machine actively refused it.</p>
  </blockquote>
  
  <p>I'm running the application from within company network. Does service bus requires some firewall port to be opened?</p>
  
  <p>Thank you.</p>
