In this practice, you will configure secure dynamic registration, secure zone replica tion, and then use dnscmd to secure DNS. Complete the following exercises. If you are unable to answer a question, review the lesson materials and try the question again. You can find answers to the questions in the Questions and Answers section at the end of this chapter.

Domain Functional Levels As you learned in 1, domain functional levels (formerly known as domain modes) provide a way to enable domain-wide Active Directory features within your network environment. Four domain functional levels are available: Windows 2000 mixed (default), Windows 2000 native, Windows Server 2003 interim, and Windows Server 2003.

Windows 2000 mixed When you first install or upgrade a domain controller to a Windows Server 2003 operating system, the domain controller is set to run in Windows 2000 mixed functionality. The Windows 2000 mixed functional level allows a Windows Server 2003 domain controller to interact with domain controllers in the domain running Microsoft Windows NT 4, Windows 2000, or Windows Server 2003. Windows 2000 native The Windows 2000 native functional level allows a domain controller running the Windows Server 2003 operating system to interact with domain controllers in the domain running Windows 2000 or Windows Server 2003. You can raise the functional level of a domain to Windows 2000 native if the domain controllers in the domain are all running Windows 2000 Server or later. Windows Server 2003 interim The Windows Server 2003 interim functional level allows a domain controller running the Windows Server 2003 operating sys tem to interact with domain controllers in the domain running Windows NT 4 or Windows Server 2003. The Windows Server 2003 interim functional level is an

Complete the following steps to configure secure dynamic registration: 1. Log on to the Tailspintoys.com domain as an administrator. 2. Open the Start, Administrative Tools, DNS console. 3. Right-click the zone that you want to configure, and then select Properties. 4. On the General tab, in the Dynamic Updates area, select Secure Only from the list, as shown in Figure 3-5.

option only when upgrading the first Windows NT domain to a new forest and can be manually configured after the upgrade. This functional level does not support domain controllers running Windows 2000.
