When Exchange Server needs to extract information from Active Directory it does so by using
Requires Free Membership to View
Lightweight Directory Access Protocol (LDAP) queries. But Exchange Server does not perform these LDAP queries directly.
Instead, Microsoft has developed three special services that act as intermediaries between Exchange Server and Active Directory: DSAccess, DSProxy, and the SMTP categorizer.
These components are responsible for communicating with Active Directory and then providing Exchange Server with the information that it needs.
In this tutorial, Exchange MVP Brien Posey describes the role and purpose of these services in the Exchange Server and Active Directory infrastructure.
