How to find the IPs and Usernames of Users Logged In on your Network

Install and Run Windows Powershell

Give yourself unrestricted script access:

Set-ExecutionPolicy Unrestricted

Make a list of IPs to query and put it in a text file (1 IP per line).

Modify script below and put it in a text file with extension .ps1 (like script.ps1)

$ErrorActionPreference = 'SilentlyContinue'
$computers = Get-Content g:scriptipaddress.txt
foreach($computer in $computers) {
$ping = Test-Connection -ComputerName $computer -Count 1 -Quiet
$computerName = [system.net.dns]::Resolve("$computer")
#$hostname = $computerName.HostName
$shortHostname = $computerName.HostName.Split(".")[0]
if ($ping -eq 'True')
    {
        $UserName = (Get-WmiObject -ComputerName $computer win32_ComputerSystem).UserName
        Write-Host "$shortHostname  $UserName" -ForegroundColor Green
        #Write-Host "$hostname is pingable" -ForegroundColor Green
    }
else
    {
        Write-Host "$computer is not pingable" -ForegroundColor Red
    }
}
