Exchange 2000 has been the driving reason
behind many companies' move to Active Directory.
Exchange 2000 requires an Active Directory infrastructure, and the
dependencies it places on AD are not small. In fact, the Exchange
2000 schema extensions roughly double the size of the default Active
Directory schema. There are also restrictions on the location of your
domain controllers relative to the Exchange servers. For these
reasons and the critical nature of email, calendar, and collaboration
services, all of which Exchange can provide, it is clear that
Exchange 2000 can be the most significant application you integrate
into Active Directory.
In this chapter, we will briefly touch on some of the important
issues regarding the integration of Exchange with Active Directory.
We'll cover how to prepare the forest for Exchange
and describe some of the changes this causes. Finally, we will review
the Active Directory Connector (ADC), which aids in the transition
from Exchange 5.5 to Exchange 2000.
