Activate it
DHCP
For a Windows based system you use the DHCP MMC snapin console. This is installed when the DHCP server service is installed. For Linux and Unix based systems you can edit the DHCP configuration file in /etc
Windows Server Family, Linux are some examples. And also there are some routers that have the DHCP service enabled.
A DHCP server will privide a client with a valid IP address for the network for which the DHCP server is providing a service.Where there is no DHCP server the IP address for a client must be set manually. When doing this care must be taken to ensure that two IP addresses are not set the same on the network.
because when the service is stopped the database is free and any chnages can be done and in restoring the database file is overwritten by system.when service is started again the DHCP database file is loaded again and one gets the retored database entries reflecting.
