之前有寫過以下POWERSHELL

$username = $env:USERNAME
$computers = Get-ADComputer -Filter * | Select-Object -ExpandProperty Name

$loggedIn = $false
$sessionId = $null

foreach ($computer in $computers) {
    $sessions = query user /server:$computer 2>&1
    foreach ($session in $sessions) {
        if ($session -match "\s+$username\s+") {
            $loggedIn = $true
            $sessionId = $session.Split(" ")[2]  
            break
        }
    }
    if ($loggedIn) { break }
}


if ($loggedIn) {
    Write-Host "用戶 $username 在 $computer 上已登入，強制登出..."
    logoff $sessionId /server:$computer
    exit 0
} else {
    exit 0  
}

可是改來改去都不成, 放棄了
