deny permissions issues

Hi,
i'd like to deny permissions on system objects to the public role in a
database.
I have tried using the following commands without any success:
DENY SELECT ON SCHEMA::sys TO public
or
DENY SELECT ON sys.sysobjects TO public
Can someone tell me what is wrong in my commands?
Thx,
ChrisHello Chris
I am not sure what is the reason to revoke SELECT on objects in sys schema
because resultsets will be filtered already by permissions. Anyway here is
statement you can use:
REVOKE SELECT ON sys.sysobjects FROM public
