See if the port is occupied under Windows and which program the port is taking up

How to see if a port is being consumed

Enter "Netstat-an" in the command prompt to display all open ports on this machine. The following table is a specific description.

Data columns	Description
Propo	Refers to the protocol name used by the connection
Local address	is the local computer IP address and the port number that the connection is using
Foreign address	Refers to the IP address and port number of the remote computer that is connecting to this port
State	Indicates the TCP connection status if stat displays listening is occupied

Eg: Find out if the specific "8080" port is occupied, what the program occupies

Enter Netstat-aon|findstr "8080" in the command prompt, and if there is a message indicating that a program is using the "8080" port, then no program occupies the port

Take this as an example: TCP 127.0.0.1:8080 0.0.0.0:0 LISTENING 20444

The above indicates that the port is occupied by a process number of 20444, and continues with the following command: The Tasklist|findstr "20444" console appears:

Java.exe 20444 Console 0 43,288 K

See, Java.exe takes up this 8080 port number.
