When configuring each name service, you must take into account both the client and the server.
The three name service options (local, NIS, and DNS) work independently of each other.
Local name service enables you to add or delete hosts and their respective addresses.
NIS enables you to add or delete the Netra server as an NIS client, master or slave server.
DNS requires you to configure two independent pieces: a client and a server. If you configure the Netra server as a DNS server, it is usually best to also be a client of this DNS server. (Note that you must configure the DNS server first and then configure it as a client.)
