—The Problem
How do I find out which process is listening on a TCP or UDP port on Windows?
The Solution
We can do this using netstat:
- Open the Start Menu and type “cmd”.
- Right-click the Command Prompt icon and choose “Run as Administrator”
- Enter the following command:
netstat -abno
-ashows all connections and listening ports.-bshows the executable responsible for each connection or listening port.-nshows the IP address and port numbers numerically.-oshows the process ID for each connection or listening port.
Alternatively, you can view details about listening ports with the Resource Monitor GUI. This GUI is accessible from the performance tab of Task Manager, or through running resmon.exe.
