DHCP in Windows Server 2008

IP Address  is Internet Protocol Address.This address is assigned to every device to communicate within the network.

192.168.0.1 is one of the example of an IP address.If we assign this address to one computer, the second computer address can be 192.168.0.2 , and the third may be 192.168.0.3 and so on............ 

Let us come to our topic DHCP. First I will tell what is DHCP? DHCP is a service given by most of the server operating system to automate the IP address process. ie, in a corporate company may have more than 100 computers, it may be a difficult task for the network administrator to manage all of these settings.So that he will create a DHCP server.We can do that in 2008 server, before we move on let us check what are the advantages of DHCP server in a network.

Benefits of DHCP

In Windows Server 2008, the DHCP Server service provides the following benefits:

• Reliable IP address configuration. DHCP minimizes configuration errors caused by manual IP address configuration, such as typographical errors, or address conflicts caused by the assignment of an IP address to more than one computer at the same time.
• Reduced network administration. DHCP includes the following features to reduce network administration:
• Centralized and automated TCP/IP configuration.
• The ability to define TCP/IP configurations from a central location.
• The ability to assign a full range of additional TCP/IP configuration values by means of DHCP options.
• The efficient handling of IP address changes for clients that must be updated frequently, such as those for portable computers that move to different locations on a wireless network.
• The forwarding of initial DHCP messages by using a DHCP relay agent, thus eliminating the need to have a DHCP server on every subnet.
