I have novell 6.5sp6 and Zfd 7sp1.

I have created a policy with "enable local user" with member of equal to "administrator" because I have some applications that require this.

I have blocked the access to control panel by GPO but the user as is administrator can run and manage the "user accounts".
is there a way to block this?
My english is poor so I hope that I have explain my problem clear enough.

Please can someone give me some suggestions?

thanks for all
