Well from his post
 Quote:
dynamically set through the logon script (user level permissions). Setting permissions on the printer doesn't do what I want for several reasons.


The DYNAMIC during logon to me is the hack as it would also seem to indicate that it needs to be turned on/off on the fly during logon, normal user wouldn't have rights to set such permissions.
He also indicates that permissions does not do what he wants so that's why I was looking more at hacking the Registry.

Oh well - suppose there needs to be more feedback from him as to why permissions lock down doesn't do what he wants.
