To prevent these misconfigurations all Appletalk server should be configured as 'END NODE' devices. End node device do not assign netowrk numbers nor do the advertise zones. The only information necessary to configure a endnode device is the name of the zone to advertise in. If a improper zone name is configured no other users will be afffected. These resources, generally provided by departments, include file servers, printers and modems.
Zones can span physical network boundaries and can be configured to exists on all network segments.
In this way a zone organizational structure could be used to display a simplified list of departmental devices available to a widely distributed campus department or work group. To support the distributed desktop locations of the campus departments it is recommended that zones be based on a departmental or owning organization structure and distributed throughout the network. Thus each department would start with one zone using a simple abbreviation for the zone name. Larger departments, such as Medicine or Surgery, could instead, or in addition, setup a number of smaller distributed zones by generating divisional abbreviations for their zone names. If the number of devices per zone becomes too large, departments are then encouraged to introduce a geographically based organization to their zone name.
