title: How to check if port is open on a remote server with batch file and without third party software?
body: <p>As <a href="https://stackoverflow.com/questions/1168317/check-status-of-one-port-on-remote-host"><strong><em>this question</em></strong></a>  is closed (where I intended to answer first) I'm opening this one.</p>
  
  <p>On some machines it is forbidden to install/download binaries so I want to know how can I check if a port on a remote machine is open using only native windows script capabilities.</p>
