  1. I recieve a cannot validate argument error!! Are you missing a parameter is your script?

    Add-ADPrincipalGroupMembership : Cannot validate argument on parameter ‘Identity’. The argument is null. Supply a non-null argument and try the command again.
    At I:\Office365\Scripts\bldg500 computers1.ps1:10 char:31
    + Add-ADPrincipalGroupMembership <<<< $b tjxg-laptop-computers-bldg-500c
    + CategoryInfo : InvalidData: (:) [Add-ADPrincipalGroupMembership], ParameterBindingValidationException
    + FullyQualifiedErrorId : ParameterArgumentValidationError,Microsoft.ActiveDirectory.Management.Commands.AddADPrincipalGroupMembership

    foreach ($computer in $computers)
    {$dns=get-adcomputer $computer
    $b=$dns.distinguishedname
    Add-ADPrincipalGroupMembership $b ‘GROUPNAME’
    }
