### The LAN Directory

The LAN directory provides a list of the targets on a LAN that are available to the controller. When the controller connects directly with the targets via IPX/SPX, NetBIOS, or TCP/IP, the LAN directory is optional. When the controller connects with the targets through a gateway, the LAN directory is required.

Install one LAN directory per logical LAN. If you install more than one LAN directory on a logical LAN, give each a unique name.

The LAN directory also keeps a list that associates the workstation's physical address on the LAN with a nickname that makes the target name easy to remember. This list also enables the controller to find targets quickly. You can install the LAN directory on the target, gateway (if present), or on any workstation on the same LAN as the target.
