Hi I manage a fairly large school and I want to use Icacls to set permissions on quite a number of our machines that are running XP service pack 3. I would like to set the administrative tools folder that is in the start menu so the studentscannot open the folder but only admins can. I am having problems with the syntax. I have seen a number of examples that use a switch that resets the inheritance but it doesn't seem to work correctly. Below is what I am using. Any help will be welcome. Thanks.

Icacls "c:\Documents and Settings\All Users\Start Menu\Programs\Admistrative Tools" /inheritance:r /grant:r "Administrator":(OI)(CI)F
I am getting a invalid parameter error for "/inheritance:f" I have based the above on this article. Managing Permissions from the Command Line
