• Multimaster updates and enhanced security are based on the capabilities of Active Directory.

• Zones are replicated and synchronized to new domain controllers automatically whenever a new

one is added to an Active Directory domain.

• Integrating storage of DNS zone databases in Active Directory streamlines database replication

planning.

• Directory replication is faster and more efficient than standard DNS replication.

For more information on the benefits of Active Directory integrated DNS read the Help and

Support center documentation in Windows Server 2003.

PDC Emulator

Now that the Windows NT 4.0 PDC has been upgraded to a Windows Server 2003 domain

controller, the new Active Directory forest and domain run in Windows Server 2003 interim mode.

This mode allows continued communication with the Windows NT 4.0 BDCs. In fact, the new

Windows Server 2003 domain controller looks like a Windows NT 4.0 PDC to the BDCs. This

computer is the first in the Active Directory domain, so it assumes all the FSMO roles. Remember,

the PDC emulator role is the component that makes this server look like a PDC.

DHCP

Because the domain is now functioning as an Active Directory domain, services should be tested

to make sure everything is functioning properly. One service of importance is the DHCP service.

Only authorized DHCP servers are allowed to hand out TCP/IP addresses in Windows Server

2003. To test this, the DHCP administrator snap-in can be opened from Administrative Tools

and the DHCP server added to the list of managed DHCP servers. If the server object displays a

red arrow in the lower-right corner, the server needs to be authorized. This can be done by right-

clicking the server object, and then clicking authorize. To see the change, the screen may need

to be updated. Notice the options on the following screen.
