Vista - Local Admin Group

I am trying to find out the members of local administrators group on my
machine.

$Admin=[adsi]"WinNT://./Administrators,Group"
$Admin.psbase.Invoke("Members")

but the Invoke("Members") method returns a COM object , which I am not sure
how to parse.

PS > $Admin.psbase.Invoke("Members").Gettype()

IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True False __ComObject
System.MarshalByRefObject

I think there is a shortcoming in the .NET classes that handle WinNT. You
would think you'd be on the right track. For example, using the LDAP
provider a script like this works just fine.

$Grp=[ADSI]"LDAP://CN=SAPIEN Authors,OU=SAPIEN,DC=MyCo,DC=local"

#create an array object from current group members
$grpMembers=@($grp.Member)

#display current group membership
Write-Host "There are currently" $grpMembers.Count "members in" $grp.Name
foreach ($user in $grpMembers) {$user}

I thought it would also work with the WinNT provider but I get the same
results. I can get some information about the group but not the members
either.

For WinNT provider use this script

$objRoot = [ADSI]"WinNT://./Administrators,group"
$objGrpMembers = @($objRoot.psbase.Invoke("Members"))
Write-Host "There are currently" $objGrpMembers.Count "members in"
$objRoot.Name
$objGrpMembers |Format-Table -HideTableHeader @{e={""};w=6},
@{e={$_.GetType().InvokeMember("Name", 'GetProperty', $null, $_,
$null)};w=21}, @{e={$_.GetType().InvokeMember("Class", 'GetProperty', $null,
$_, $null)};w=8}, @{e={$_.GetType().InvokeMember("AdsPath", 'GetProperty',
$null, $_, $null)};w=50}
