If you decide that a certain service should not be available to your remote users, you must remove that service from the services granted to Guests, Registered Users, and Windows NT Users. The following procedure takes you through each kind of remote user access to ensure the service has been removed from each of them.
To remove a service from remote user access
From the Setup menu, choose Security.
In the Security dialog box, click the Guests tab. If the service you want to remove is selected, deselect it.
Note: To prevent remote users from asking for permission to use the service, clear the Users May Ask for Permission to Use Unchecked Services checkbox. However, this may lock out services that you want to keep available for Ask For Permission users.
Click the Registered Users tab and select any Registered Users who should not have access to the service. If the service you want to remove is selected in the list of services granted to that Registered User, deselect it.
Click the NT Users tab and select any Windows NT Users who should not have access to the service. If the service you want to remove is selected in the list of services granted to that Windows NT User, deselect it.
Click OK to close the Security dialog box.
