Powershell – Unable to identify properties on item in powershell

active-directorypowershell

In attempting to answer this question I came up against something that has bugged me for a while, and I have not been able to find an answer for.

The following script block will list the names of all members of the local administrators group.

$group = [ADSI]"WinNT://./Administrators"
@($group.Invoke("Members")) | foreach {$_.GetType().InvokeMember("Name", 'GetProperty', $null, $_, $null)}

However it will list only the names, and no other properties.

I'm fairly sure that there are other properties of Members that I could extract but I don't understand how I would go about identifying what those other properties are.

I don't necessarily need to know the additional properties of that item, this is more a question of how I would go about finding them.

(I apologise if this is all a bit vague, I'm very much self taught at all of this and I'm well aware that I might be barking up the wrong tree and/or making regular horrible mistakes.)

Please see available properties here:

and a similar example to your question:

Since you are already getting a list of members names for the group, to get the details of the members I would just requery again, except against the individual user instead of the group.

PS C:\> $group = [ADSI]"WinNT://./administrators"
PS C:\> $members = $group.Invoke("Members") | %  {$_.GetType().InvokeMember("name", 'GetProperty', $null, $_, $null) }
PS C:\> $membersObjects = @() ; $members | % { $membersObjects += [ADSI]"WinNT://./$_" }
PS C:\> $membersObjects | gm
