Checking YOUR PC ports

1. Open a cmd window (start, run, "cmd")

2. Type: netstat -a | find "LISTENING"
Which gives you something like this.

The PORT numbers in this example include 8880, 53100, etc.

TCP ANTEC:epmap ANTEC:0 LISTENING
TCP ANTEC:microsoft-ds ANTEC:0 LISTENING
TCP ANTEC:8880 ANTEC:0 LISTENING
TCP ANTEC:53100 ANTEC:0 LISTENING
TCP ANTEC:1036 ANTEC:0 LISTENING
TCP ANTEC:12080 ANTEC:0 LISTENING
TCP ANTEC:netbios-ssn ANTEC:0 LISTENING

You can also PIPE the command into a file with this command:
netstat -an |find /i "listening" > c:'openports.txt


3. Download TCPView v. 2.33 from Sysinternals < http://www.petri.co.il/software/tcpview233.zip > Unzip it and run it.

4. In the first column when running TCPView (Processes), right click on process and then click on process properties to see information about the process using the port.

After you right click on it. You can see that the process service.

All this worked easily and quickly for me yesterday, when doing a little detective work.
