How To Find Open Ports On A Windows Server

[PMagic]

Hi,

Well, the easiest way is to use websites such as Port Scan Tool - Quick scan on common TCP Ports - MxToolbox to scan for open ports.

You can also use netstat command line on your server to find a open port. Let's see how :

* To display all open ports, open command prompt (Start -> Run -> Cmd), type netstat and press Enter.
* To list all listening ports, use netstat -an |find /i listening command.
* To see what ports your computer actually communicates with, use netstat -an |find /i established
* To find specified open port, use find switch. For example, to find if the port 1433 is open or not, do netstat -an |find /i 1433.

* To display all open ports, open command prompt (Start -> Run -> Cmd), type netstat and press Enter.
* To list all listening ports, use netstat -an |find /i “listening” command.
* To see what ports your computer actually communicates with, use netstat -an |find /i “established”
* To find specified open port, use find switch. For example, to find if the port 1433 is open or not, do netstat -an |find /i “1433“.

This tool provides information of specific open ports only. I use nmap to get a list of all open ports of any system. eg: nmap -v -P0 -A x.x.x.x where x.x.x.x is the IP address of the target machine
