Vista - Script error when run through RemoteAPP

We have a Windows 2008 Server running Terminal Services with RemoteAPP.

When I launch the remoteapp, a VB Script is called from a Group Policy
Object that does some mapping. I get an error in Line 12, Char 1, that
reads "The specified module could not be found."

The script starts like this...

Option Explicit

Dim strLogName, bolWriteLog, bolManagePrinters
Dim objNetwork, objDrives, objDict, objComputer, objShell, objFileSystem,
objLogFile, objRootDSE, objTrans
Dim strComputerName, strDomain, strUser, strAdsPath, strNetBIOSDomain,
strDNSDomain, strTemp, strLogPath, i

Set objNetwork = CreateObject("WScript.Network")

where the "S" in the last line is the character referred to in the error.
There are several comments that i did not include here.



If I use a Remote Desktop session instead of the RemoteAPP session, the
script runs fine. Any idea how to correct this?
