How to view ports under Windows by program

Sometimes when installing the program, the XX port is occupied, you can use the cmd command to see what the program occupies 1. Netstat-ano view the corresponding port corresponding program PIDFor example:

2. C:\>netstat-ano
4. Active Connections
6. Proto Local Address Foreign address State PID
8. TCP 0.0.0.0:135 0.0.0.0:0 LISTENING 1760
10. TCP 0.0.0.0:445 0.0.0.0:0 LISTENING 4
12. TCP 0.0.0.0:2967 0.0.0.0:0 LISTENING 660
14. TCP 0.0.0.0:3389 0.0.0.0:0 LISTENING 1712
16. TCP 0.0.0.0:3934 0.0.0.0:0 LISTENING 728
18. TCP 0.0.0.0:10700 0.0.0.0:0 LISTENING 4920
20. TCP 10.186.20.116:21 0.0.0.0:0 LISTENING 272
22. TCP 10.186.20.116:80 0.0.0.0:0 LISTENING 4516

You can see that the 21-port-occupied process PID is 272. 2. Tasklist view the corresponding PID number of the program

1. TASKLIST/FI "PID eq pid"

Cases

1. C:\>TASKLIST/FI "PID eq 272"
2. Image name PID session name Session # Memory usage
3. ========================= ====== ================ ======== ============
4. ServUDaemon.exe 272 Console 0 3,980 K

3. If you want to release the port with the Tskill PID commandexample, if you want to release port 21

1. Taskill 272
