Remotely query system variables?

Hi,

I am currently writng a platform validation tool that will run post server
build from a remote server. In order to make it OS version agnostic I need to
remotely query local system variables - specifically %SYSTEMROOT%.

As it wont be run locally I can't use "objShell.ExpandEnvironmentStrings" so
I have been trying the "Win32_Environment" wmi class. Only issue is that
this seems to only return variables under
"HKLM\System\CurrentControlSet\Control\
Sessionmanager\Environment" of which %SYSTEMROOT% is not there?

I have searched the registry and can't seem to find any reference of where
this get set.

Does anybody have any idea or functions that can recieve this information?

Basically I need to mimic the functionality of
"objShell.ExpandEnvironmentStrings" but remotely.

Thanks,
Rob

PS: I am currently using this, but it's kind a single use pointless function.
I really want something that can do all remote system variables rather than
needing two separate functions.

Function GetRemoteWinDir(strServer)

Dim objWMIService
Dim colOS
Dim objOS

Set objWMIService = GetObject("winmgmts:\\" & strServer & "\root\cimv2")
Set colOS = objWMIService.ExecQuery("Select SystemDirectory from
Win32_OperatingSystem")
For Each objOS in colOS
GetRemoteWinDir = Replace(objOS.SystemDirectory, "\system32", "")
Next

Set objWMIService = Nothing

End Function

The SystemRoot Value Name, a string data type at
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion"
