If you try to use NIS+ as your data store, DHCP Manager might not offer NIS+ as a choice for the data store. If you use the dhcpconfig command, you might see a message stating that NIS+ does not appear to be installed and running. Both these symptoms mean that NIS+ has not been configured for this server, although NIS+ might be in use on the network. Before you can select NIS+ as a data store, the server system must be configured as an NIS+ client.
Before you set up the DHCP server system as an NIS+ client, the following statements must be true:
The domain must have already been configured.
The NIS+ domain's master server must be running.
The master server's tables must be populated.
The hosts table must have an entry for the new client system, the DHCP server system.
Setting Up NIS+ Client Machines in System Administration Guide: Naming and Directory Services (NIS+) provides detailed information about configuring an NIS+ client.
