$user = "username" $sid = get-aduser -identity $user | select -expandproperty sid $computerlist = get-adcomputer -filter * | select -expandproperty dnshostname  foreach ($computer in $computerlist){     if (test-connection -computername $computer -quiet -count 1) {         $reg = [microsoft.win32.registrykey]::openremotebasekey('users', $computer)         if ($reg.opensubkey("$sid")) {             write-output "$user found on $computer."         }         else {             write-output "$user not found on $computer."         }     }     else {         write-output "$computer unreachable."     } }
