Microsoft Exchange 2000 Server gives administrators the ability to view the topology generated by Directory Access. Directory Access also gives administrators the ability to manually add and remove servers from the topology. Exchange 2000 Server Service Pack 2 (SP2) provides new information about the Directory Access topology.

The following topics provide information about using Directory Access:

• View the Topology
• Automatically Create the Topology
• Manually Create the Topology

Important   In a multi-domain Active Directory forest, a computer running Exchange in a child domain cannot contact a global catalog server when all domain controllers in the parent domain go offline. Without at least one global catalog server to provide Active Directory information, Exchange cannot start. To ensure that a computer running Exchange anywhere in an Active Directory forest is always able to access a global catalog server in any other part of the forest, you must configure two-way trusts between every domain. This is the only way to provide true fault-tolerance for your Exchange organization.
