Chapter 4: The Site Replication Service
4.1 Introduction
The Site Replication Service (SRS) is for the most part a not-so-well-understood component of Exchange 2000. In general, it is believed to be a new component of Exchange that allows an Exchange 2000 server to synchronize directory information with an Exchange 5.5 server. To some extent this is true, but, if anything, the SRS could be said to be old technology. The SRS is a reincarnation of the legacy Exchange 5.5 Directory Service. Its function in life is to allow an Exchange 2000 server to participate in Exchange 5.5 style directory replication. Why might an Exchange 2000 server need to do this? Surely the ADC with its concept of ConfigCAs provides all of the Exchange 5.5/Exchange 2000 interoperability that is required? This chapter sets out to clear up all of that confusion.
4.2 The SRS does not job share with the ADC!
One thing should be borne in mind: Only the ADC provides the mechanism to perform directory synchronization between the Exchange 5.5 Directory Service and the Active Directory. The SRS plays no real direct part with this exchange of information (although it can be involved and we'll discuss this later). But what the SRS does do is present itself as an Exchange 5.5 Directory Service to other Exchange 5.5 servers while running on an Exchange 2000 server. You could say that the SRS fools other Exchange 5.5 servers into thinking that they are communicating (on a directory level at least) with an Exchange 5.5 server, when in reality...
