Planning, Implementing, and Troubleshooting DHCP
The Dynamic Host Configuration Protocol (DHCP) is one of those services that has proven itself as a valued solution on TCP/IP networks of all sizes and complexities. With the advent of DHCP, gone are the days administrators previously faced of manually providing and tracking IP addresses for hundreds or thousands (or even hundreds of thousands) of network clients. This chapter examines the DHCP service and how it is planned for and implemented in a Windows Server 2003 environment.
Although no exam objectives are directly addressed in this chapter, we felt the material presented here was still relevant enough to warrant coverage. Additionally, it's not out of the realm of possibilities that you will need to understand the information presented here on test day (and after) as you carry out your day-to-day administrative activities. Please do take the time to read through this chapter, as you stand a good chance of having at least one question on your exam that deals directly or indirectly with the planning, implementation, or troubleshooting of the DHCP service.
