WAIK 1.1 Scripting Error

Anybody come across an error when running a WMI query under WinPE2.x.
Reports "Invalid Syntax" at line:

Set objWMIService = GetObject("winmgmts:\\" & strComputer &
"\root\cimv2")

This works ok when running under WinPE2.0 as provided by WAIK 1.0, but
fails with WAIK 1.1 - what's changed?

The full script is to change the DVD drive letter (see attachment)
