MS Exchange Server 2003 Interview Question:

How do I remove the ADC after moving all of my users to an Exchange 2003 server?

First, you need to use the Exchange 5.5 Admin program to delete the directory replication connectors (Org | Site | Configuration | Connections). Once you have deleted the connections, you need to be logged on with an account with Schema Admin privileges to delete the ADC connector.
