Question

Can I use a PowerShell script to return the name of the application process that is using a port?

Answer

Below is an example PowerShell script that can be used.

$portNumber = 5003  # Replace with the port number you're interested in

$connection = Get-NetTCPConnection | Where-Object { $_.LocalPort -eq $portNumber }

if ($connection) {
    $process = Get-Process -Id $connection.OwningProcess

    Write-Host "Port $portNumber is being used by process:"
    Write-Host "Process Name: $($process.ProcessName)"
    Write-Host "Process ID: $($process.Id)"
} else {
    Write-Host "Port $portNumber is not in use."
}
