Microsoft Exchange 2000 Server Directory
Access is a caching and abstraction layer between all
Exchange services and Windows 2000 Active
Directory. Exchange uses Directory Access to discover
servers in your organization that Exchange services use to query
Active Directory.
Because Exchange relies on these servers for Active Directory
queries, Directory Access develops a topology of servers to ensure
that Exchange always has servers for Active Directory queries and
uses these servers in the most efficient way.
If you manually
add servers to the topology, Directory Access will not discover
other servers until you return to automatic discovery. When
the Automatically discover servers check box is cleared,
Directory Access uses only servers you specify in the topology and
will not discover other servers until the check box is
selected.
If you manually
add servers to the topology, Directory Access will not discover
other servers until you return to automatic discovery. When
using a manually created topology, if domain controllers in this
topology fail, Directory Access continues to use these servers for
Active Directory queries. To ensure successful Active Directory
queries, replace any failed servers in the topology or return to
automatic discovery.
