title: Used port not showing up in netstat -a result
body: <p>This issues started recently when I am trying to start active-mq (which by default starts on port 61616). But suddenly it stopped coming up with JVM_BIND issue on that port. The problem did not go away even after restarting the computer.</p>
  
  <p>Main problem is that 
  netstat -a command on Windows 7, does not show that 61616 is consumed. But when I wrote a simple Java program to bind a socket to that port, I wasn't certainly able to! </p>
  
  <p>I eventually started active-mq by moving to a different port. But, can anybody please help me find why all the ports are not showing up in netstat -a result? Thanks.</p>
