Chapter 10: DHCP
Odds are that DHCP, unlike WINS, is alive and well on your enterprise network. When clients and servers can no longer communicate, and you see Automatic Private IP Addressing (APIPA) popping up on clients around your network, it's time to sound the DHCP problem siren.
This chapter answers the call by first showing you three handy tools for DHCP troubleshooting: the DHCP MMC snap-in, audit logging, and dhcploc. Further into the chapter, you will learn how to isolate and correct problems on both DHCP clients and DHCP servers, as well as problems relating to the Active Directory. In the event that you have DHCP relay agents deployed on your network, the chapter also includes a section on identifying problems relating to a relay agent and then provides steps on how to correct this type of problem.
DHCP problems can be localized to a single client computer or can have far-reaching consequences, such as when an entire network segment can no longer communicate with the rest of the network. When the DHCP problem siren rings (if we were only so lucky to have one), this chapter helps you answer the bell and come out punching.
