Dsquery server

unique de chaque entre. Une valeur de rdn affiche le nom unique relatif de chaque entre. La valeur par
dfaut est le nom de domaine.
NB : epwc doesn’t exist for Dsquery computer

so even if i’m not sure it’s the best way, the onlypossible answer is using “Get-ADComputer and specify the
lastLogon property”
