In some DHCP server settings, we need to note the authorization settings. In this case, how does one authorize the Windows Server 2008 DHCP Server? The installed DHCP role of Windows Server 2008 does not immediately provide services for the DHCP client. It must be Authorized by an Authorized program. The principles and precautions of DHCP Server authorization are as follows: (the DHCP Server mentioned here refers to the DHCP Server role created in Windows Server 2008 operating system)
1. the DHCP server can be authorized only in the Active Directoy domain environment.
2. the DHCP server in the Active Directoy domain environment must also be authorized;
3. Only members of Enterprise Admins (Enterprise Management Group) can perform authorized operations;
4. the IP address of the authorized DHCP server will be registered in the Active Directory database of the domain controller;
5. when the DHCP server is started, It queries the Active Directory database to check whether its IP address is registered in the DHCP server authorization list. If the query succeeds, the DHCP server starts the service normally and rents the IP address to the DHCP client;
6. a DHCP server that is not a domain member cannot be authorized.
7. in the same network, if two DHCP servers can be assigned, if one is authorized and the other is not authorized, the server will not provide the DHCP assignment service, DHCP assignment is only available for assigned servers;
8. if there is no authorized DHCP server in the network and there is another DHCP server (Other: not added to the Active Directory domain member), DHCP can also provide DHCP assignment;
It is worth noting that the Active Directory domain is created in the Active Directory program;
In this article, you must remember the principles and precautions for using Server 2008 to set up a DHCP role Server in a Windows AD domain environment. Otherwise, the establishment cannot be completed successfully.
