Granting users too many privileges can be a problem at times. Administrators should be aware that when a user has been assigned to any of the default local groups that user inherits security privileges applied to the groups; one of these privileges is the ability to shut down the workstation.
So let's say a Windows 2000 workstation is running some dedicated application, or is sharing a resource such as a printer. A user who is a member of any of the default local group may be able to shutdown the workstation. To prevent this from happening it is advisable to remove this capability from the default group that has the privilege of shutting down the workstation. Once you've done this, you can then add a group (or a user) that will include users who will have the privilege of shutting down the computer.
To prevent groups from shutting down the computer:
- Go to Control Panel
- Double-click on Administrative Tools
- Double-click on Local Security Policy Console
- Open the security settingsLocal PoliciesUser Rights assignment
- Double click the policy Shut Down The System
- Clear the Local Policy Setting check box for those groups that you don't want shutting down the system.
Of course, there are ways of abnormally shutting down or resetting the workstation through the power switch or reset button. Check with the hardware manufacturer to see if it has provided a way to disable these switches.
