Key Points

• RPC over HTTP works only when the client computer is running Windows XP Professional SP1 or later and Outlook 2003, and the Exchange Server 2003 server is running on Windows Server 2003.

• You can have only a single Exchange Server 2003 organization in an Active Directory forest, and an organization cannot span forests.

Key Terms

naming context Active Directory is partitioned into three naming contexts: the schema naming context, the domain naming context, and the configuration naming context. Each naming context is responsible for storing different types of Active Directory data.

operations master Active Directory functions mostly in a multimaster manner, where each domain controller is a peer. However, some functions cannot be reliably performed in a multimaster manner, so Active Directory implements them as single-master roles. The Schema Master role and the Domain Naming Master role exist only once in a forest. The Infrastructure Master role, the RID Master role, and the PDC Emulator role exist on a domain controller in each domain in the forest.
