Static IP addresses can add a lot of administrative overhead.Not only can management of static IP addresses become time consuming, but such management also increases the chances of misconfigured parameters.The TCP/IP protocol is an Active Directory operational requirement.This means that all computers on a Windows 2000 network require a unique IP address to communicate with the Active Directory.You can configure DNS registration at the server level or at the individual scope level on the DNS tab of either the IPv4, IPv6 or individual scope properties dialog box.Figure 4-4 shows configuring DNS registration for an IPv4 scope named ALPHA.
DNS registration ensures that the addresses configured in the DNS zone match the IP addresses leased by the DHCP server.
If you dont set it, you may see an empty name in your DHCP server lease section.
Now, in AD create a service account based on your naming conventions (service_dhcp2dns, fred, larry, whatever works for you).
This option is useful for organizations that haven’t configured reverse lookup zones where attempts to register PTR records cause errors in the event log.
Configuring DHCP Name Protection DHCP Name Protection allows you to protect the names that DHCP registers in DNS on behalf of DHCP clients from being overwritten by devices running non-Microsoft systems that may have the same name.
