How to find exe listening on port?

I try with netstat -ab -p tcp -n and among the results get:

  TCP    0.0.0.0:47001          0.0.0.0:0              LISTENING
Can not obtain ownership information

I am running as administrator and get that message. I also downloaded a utility to show network activity for exe's but nothing open is listening on port 47001 according to the utility.

How can I find out what is listening?

Solution 1:

Try netstat -o to get the process id (PID) and then use tasklist |findstr <pid> to see the process name and type. Task Manager also shows PID and process name.

You can combine your other switches with -o like so: netstat -bona -p tcp

Solution 2:

Since your talking about windows, you can use "netstat -b" to see which executable is using that port.

Alternatively, Sysinternal's TCPVIew does the same, but in a much better way.

Solution 3:

http://www.iana.org/assignments/port-numbers lists this port as: winrm 47001/tcp Windows Remote Management Service Ryan Mack rmack&microsoft.com 29 April 2009

Now that doesn't prove that's what using it on your computer, but it's a pretty good guess.
