Domain Models
Create diagrams that show your domain models, using one-way or two-arrows to indicate the trust relationships in your model. SMS 2003 supports the following domain models:
Windows NT domains
Windows 2000 Active Directory native mode domains
Windows 2000 Active Directory mixed mode domains
All Windows Server(tm) 2003 Domain functional levels
Windows NT Domain Model
The following are types of Windows NT domain models. See Figure 7.1 for a basic diagram of a Windows NT master domain model:
Single domain
Single master
Multiple master
Complete trust
Mixed mode (see the "Active Directory Structure" section later in this chapter)
Figure 7.1 Sample master domain model diagram
Windows 2000 Active Directory Domain Model
The Windows 2000 domain model uses Active Directory domains and trusts. You should know how your Active Directory site structure is laid out in relation to your domain model. This is important if you are using mixed mode domains. Active Directory service is compatible with Windows NT 4.0 and supports a mixed mode of operation using both Windows 2000 Server domain controllers and Windows NT Server 4.0 domain controllers.
It is recommended that you be aware of the status of your Active Directory migration. Which of your domains are in mixed mode? Typically, after all of your Windows NT domain controllers are upgraded to Windows 2000, native mode is enabled on the domain. Figure 7.2 illustrates the different mode types.

Windows Server 2003 Active Directory Domain Model
Windows Server 2003 introduces a way to enable domain-wide Active Directory features in your network environment. This is called domain functionality, and is expressed in four different levels, as seen in Table 7.8.
Be aware of the status of your Active Directory migration. SMS 2003 supports all four domain functional levels.
