"You do not have the necessary permission,.........Have your system Administrator or the person who created this object establish the appropriate permission for you"
sounds like access is doing what its expected to do - its telling your users that they don't have adequate security permissions if thye shuld have then its up to the system administrator or the person who created the object (YOU) to fix - how much more explicit could it be - your security is working.
do a google for Access security
follow the steps on the microsoft site for securing your Access applciation
hint: its to do with the admin user account / and or default workgroup files
