DHCP installation in Windows Server 2008

Windows 2008 Server builds DHCP service:

DHCP is an abbreviation for Dynamic host Configuration Protocol, the predecessor of which is BOOTP. BOOTP was originally used for a network without disk host connection: The network host uses the boot ROM instead of the disk to start and connect to the network, BOOTP can automatically set the TCP/IP environment for those hosts. But BOOTP has a disadvantage: you need to obtain prior to the client's hardware address, and the corresponding IP is static. In other words, BOOTP is very lack of "dynamic", if in a limited IP resource environment, BOOTP one by one corresponding can cause very serious waste of resources. DHCP can be said to be the enhanced version of BOOTP, it is divided into two parts: one is the server side, and the other is the client. All IP network settings data are centrally managed by the DHCP server and are responsible for handling the DHCP requirements of the client, while the client uses the IP environment data that is assigned from the server. Compared to BOOTP, DHCP through the concept of "lease", efficient and dynamic allocation of client TCP/IP settings, and, as a compatibility consideration, DHCP also fully take care of the requirements of BOOTP client. The allocation form of DHCP first, you must have at least one DHCP server working on the network, which listens to DHCP requests from the network and consults TCP/IP settings with clients. It provides three types of IP positioning:

Experimental environment: Windows 2008*1 IP Address: 192.168.1.1

Windowsxp*1 IP Address: Automatically get

Experiment Step ①: Open Server Manager → Click Add role

② Check DHCP server

③ configuration scope, or after the installation is completed in the configuration
