MCSA/MCSE 70-291: Implementing, Managing, and Maintaining a Microsoft Windows Server 2003 Network Infrastructure (Exam Prep)

Objectives

Microsoft lists the following objectives for the DHCP portion of the "Implementing, Managing, and Maintaining IP Addressing" section of Exam 70-291, "Implementing, Managing, and Maintaining a Microsoft Windows Server 2003 Network Infrastructure":

Manage DHCP.

  • Manage DHCP clients and leases.

  • Manage DHCP Relay Agent.

  • Manage DHCP databases.

  • Manage DHCP scope options.

  • Manage reservations and reserved clients.

  • One of the first few network services you will likely deploy and configure when rolling out a production Windows Server 2003 network is the DHCP service. DHCP is highly integrated with both Active Directory and the dynamic DNS (DDNS) service. To meet this objective, you must have a thorough understanding of the workings of DHCP and also how to configure it for use in a network.

Troubleshoot DHCP.

  • Diagnose and resolve issues related to DHCP authorization.

  • Verify DHCP reservation configuration.

  • Examine the system event log and DHCP server audit log files to find related events.

  • Diagnose and resolve issues related to configuration of DHCP server and scope options.

  • Verify that the DHCP Relay Agent is working correctly.

  • Verify database integrity.

  • Installing and configuring the DHCP service does not relieve you of monitoring and managing it over time. The ability to monitor, manage, and troubleshoot the DHCP service on a network is critical to the ongoing health of the network as a whole. You should be able to use all the tools available to you to ensure that the DHCP service is operating properly, providing service to network clients.

Study Strategies

  • Be sure you understand what DHCP is, how it works, why it was created, and what enhancements Microsoft Windows Server 2003 DHCP server service adds to the protocol. DHCP has been used in Transmission Control Protocol/Internet Protocol (TCP/IP)-based networks for quite a while. Microsoft has extended the functionality of DHCP as part of its Windows Server 2003 operating system. DHCP is used to dynamically allocate IP addresses, and it also plays a critical role in registering hosts with the Domain Name Service (DNS).

  • Be sure you understand the types of scopes that Windows Server 2003 DHCP server service supports, how each works, and when you should use each in a production environment.

  • Get your hands dirty. The Step by Step exercises throughout this book provide plenty of directions and exercises, but you should go beyond those examples and create some of your own. If you can, experiment with each of the topics we discuss in this chapter to see how they work and why you would use each one.
