Many administrators usually use the netstat console tool or graphic TCPView to display information about active TCP/IP connections and open TCP ports in Windows. Instead of netstat, you can use the Get-NetTCPConnection cmdlet in PowerShell to get information about active network connections in Windows, open TCP ports, and run processes that are using the TCP/IP protocol. PowerShell makes it easy to write complex scripts to get information and monitor open TCP ports, processes, and established network connections.
