Chapter Summary

• The ADC is used to synchronize the Exchange Server 5.5 directory with Active Directory.

• The Site Replication Service enables Exchange Server 2003 to appear as an Exchange Server 5.5 directory service for seamless integration.

• After installing Exchange Server 2003 into an existing Exchange Server 5.5 site, you still use Exchange Administrator to administer the Exchange Server 5.5 servers and use Exchange System Manager to administer the Exchange Server 2003 servers.

• Troubleshooting the ADC and Site Replication Service usually involves sorting out replication problems.

• You cannot move a Site Replication Service, but you can create a new one and then delete the old one.
