WindowsServer 2003 cmd check installed roles - powershell

Question

I am creating a large batch script to check installed windows features (components) on a Windows 2003 server. I can not seem to figure out how to query server roles and display all sub-features of the role within the cmd shell. This is easy to do in Windows Server 2008 by simply using servermanager.exe or WMI, but I cannot figure out what program or cmd to use in Windows 2003. Windows Server 2003 has power shell installed, but it just seems like a glorified cmd shell in this Windows OS version. Does anyone know of a similar utility or cmd that can be used specifically on a Windows 2003 box? Thanks for your time.

You can try this function
function Get-InstalledComponents($computer = '.') {
$components_installed = #();
$reg_paths = #('SOFTWARE\Microsoft\Windows\CurrentVersion'`
+ '\Setup\Oc Manager\Subcomponents');
$reg_paths += #('SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion'`
+ '\Setup\Oc Manager\Subcomponents');
$hkey = 'LocalMachine';
$reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($hkey, $computer);
foreach ($reg_path in $reg_paths) {
$reg_key = $reg.OpenSubKey($reg_path);
if ($reg_key -eq $null) {
continue;
}
$names = $reg_key.GetValueNames();
foreach ($name in $names) {
$value = $reg_key.GetValue($name);
if ($value -gt 0) {
$components_installed += #($name);
}
}
$reg_key.close();
}
$reg.close();
if ($components_installed.count -lt 1) {
trap { ;
continue } $features = #(get-wmiobject -class 'Win32_ServerFeature' `
-computer $computer -erroraction 'Stop');
foreach ($feature in $features) {
$components_installed += #($feature.name);
}
}
return ($components_installed | sort);
}
