PowerShell: Who RDP’d into our Servers and didn’t log out

\ by

Who used remote desktop to log into our servers but didn’t log out?

##########
# Remote desktop users - who is RDPed into SQL Servers?

$AllComputersList |%{ 
    $ComputerName = $_ ; 
    # $ComputerName = 'SQLPROD'
    write-host -ForegroundColor Cyan $ComputerName
    #(qwinsta /SERVER:$ComputerName)
     
    $RDPUser = (quser /SERVER:$ComputerName 2>$null )  # Don't show us any DOS errors.
    if (!$RDPUser) {
        return # continue
    }
    $RDPUser
}

Useful tip in this script is how to redirect output. Here we redirect to NUL like this

2>$null
