Check if the computer port is open


Your NiceLabel application would like to use a specific computer port for TCP communication and you are not sure if the port is open.


You can check ports on your computer or on a computer that you want to connect.

  1. Open Windows PowerShell application.

  2. Enter the syntax:

    Test-NetConnection -ComputerName TargetComputer -Port 1234

    Where "TargetComputer" stands for your computer name or computer name that you want to connect and "1234" is the port number you want to check.
