Kent,
Sorry if this all became confusing. The problem arose because a department changed name. So we renamed the group in AD and updated the script to:

If INGROUP("newDepartment")
..
..
EndIf

Then found the script no longer worked, so we changed the script back to:

If INGROUP("oldDepartment")
..
..
EndIF

Which then worked. This is exactly what the current manual (p19) warns about and the need for the /F<date> option. Unfortunately the previous copies of the manual, we have make, no mention of this "feature".

This also coincided with a glitch in AD, now fixed, hence the confusion about whether the problem was Kix or AD.
