title: PID exists in netstat but does not exist in task manager
body: <p>I have discovered a running process with PID 26376 listening on port 9001 and 9002 as when I try to run my program(as a service) which binds to that port it fails.</p>
  
  <p>But when I try to kill it using taskkill /PID it says that the process 26376 is not found. Similarly when I try to find the process in task manager with "Show processes from all users" selected, I couldn't find it anywhere.</p>
  
  <p>Can anyone explain this? Is it a defunct zombie process? I suspect that the process listening on that port is a previous instance of my program running but what could have caused this?</p>
  
  <p>EDIT:
  Sysinternals TCPView shows the process as non-existent.
  Sysinternals Process Explorer does not show the process.
  Tasklist does not show the process.</p>
