title: How to stop a program using a port
body: <p>I want to use the port 12345 for hosting a server for an application I have, however the port is already in use by another program.</p>
  
  <p>I have already tried:</p>
  
  <pre><code>netstat -anb
  </code></pre>
  
  <p>However, none of the programs listed use this port. Doing some research online I found out that Trend Micro Security uses this port. though I used to have this Anti-Virus software installed on my computer, I have long ago switched to Norton, and am still not able to use this port.</p>
  
  <p>I use netgear, and have no problems using other ports.</p>
  
  <p>Any help will be appreciated.</p>
