Ah, thanks for the hint. Read it. ;-) Was the following just an intermediate outcome of the discussion or the final implementation? a) users from the Administrators group must run such application with elevated privileges b) standard users could be granted SeCreateGlobalObjects privilege directly or by including them into special users group which have this privilege granted. My interpretation for b): Even if standard users get SeCreateGlobalObjects granted, they still need to run the application with elevated privileges as in a)?
