When you unconfigure a DHCP server, the server daemon stops and does not start automatically when the system reboots. The server configuration file is deleted as well. Before you unconfigure a DHCP server you must decide what to do with the DHCP data files: dhcptab and the DHCP network tables. If the data is shared among servers, you should not remove the dhcptab and DHCP network tables because this could render DHCP unusable across your network. Data can be shared through NIS+ or on exported local file systems. You can unconfigure a DHCP server and leave the data intact if you do not remove the tables when prompted to do so.
