Problem
I want to see which user is logged in to a Windows workstation without having to find the computer in question.
Solution
If these are all domain members, then powershell on the DC should work:
$computername = 'SomeMachine-or-IP'Get-WmiObject Win32_ComputerSystem -ComputerName $computername | Select-Object -ExpandProperty UserName
