Error while invoking GetType. Could not find member.

Hi, I’ve been trying to get this script to pickup a Domain user (Dom1\V35678) but it never does. I get the Error while invoking GetType. Could not find member message. It picks up every other local admin. Any ideas? Thanks for any help in advance.

$computerName = '6WGPQG2'
$localgroupName = "Administrators"
	if ($computerName -eq "") { $computerName = "$env:computername" }
	if ([ADSI]::Exists("WinNT://$computerName/$localGroupName,group"))	{
		$group = [ADSI]("WinNT://$computerName/$localGroupName,group")
		$members = @()
		$Group.Members() |
		% {
			$AdsPath = $_.GetType().InvokeMember("Adspath", 'GetProperty', $null, $_, $null)
			# Domain members will have an ADSPath like WinNT://DomainName/UserName.
			# Local accounts will have a value like WinNT://DomainName/ComputerName/UserName.
			$a = $AdsPath.split('/', [StringSplitOptions]::RemoveEmptyEntries)
			$name = $a[-1]
			$domain = $a[-2]
			$class = $_.GetType().InvokeMember("Class", 'GetProperty', $null, $_, $null)
			$member = New-Object PSObject
			$member | Add-Member -MemberType NoteProperty -Name "Name" -Value $name
			$member | Add-Member -MemberType NoteProperty -Name "Domain" -Value $domain
			$member | Add-Member -MemberType NoteProperty -Name "Class" -Value $class
			$members += $member
write-output $members

Finally got a chance to play with this, and my best guess is that it’s falling apart in the COM Interop layer. You might be better off switching to a pure .NET Framework approach, or using the AD module from the RSAT. ADSI is pretty creaky these days.
