The service needs to be running, and the scope needs to be authorized before addresses may be given out.
dhcp has to be authorized

Dhcp relay agent
Server is a system that is used for providing services to clients. for example print server provides print service, dhcp service provides dhcp service
Either disable the dhcp scope, or remove the service.

Activate it
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
DHCP
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.
Without Active Directory the DHCP server cannot be authorized, and could therefore be considered a "rogue". What A.D do for a DHCP Server that it authorised to DHCP server to give an Ip add. to clients and authorised for update the DNS PTR records. and when we won't authorised DHCP with Active Directory it won't be update the the PTR records and won't be update the IP add. in DNS records.
