    Hi,

    I would like to know if there is a way to determine the forest functional level and the domain functional level, from the command line or powershell.

    Thanks in advance,

    Argi

    The powershell cmd Get-ADDomain and Get-ADForest powershell cmd will give you. You can also use free ADfind tool.
