31. 31 BASIC ADC TROUBLESHOOTING Is the ADC service running? Is a connection agreement configured? Is the container displayed in the Export Containers list? Is the Exchange Server 5.5 computer turned on and running? Is the Exchange Server 5.5 directory service running on the server? If there is only one Active Directory server, is it online? Is the ADC service running? Is a connection agreement configured? Is the container displayed in the Export Containers list? Is the Exchange Server 5.5 computer turned on and running? Is the Exchange Server 5.5 directory service running on the server? If there is only one Active Directory server, is it online?

32. 32 BASIC ADC TROUBLESHOOTING (CONT.) Did you select the object class on both the From Windows and From Exchange tabs? Did you select the directions that you want to replicate information to and from? Is the connection agreement configured to replicate in the direction you need? Does the user account that you are using on the target directory have sufficient permissions? Are any error messages logged in the server application log? Did you select the object class on both the From Windows and From Exchange tabs? Did you select the directions that you want to replicate information to and from?

39. 39 SUMMARY ADC used to connect Exchange Server 5.5 to Active Directory Connection agreement required You can install Exchange Server 2003 into an existing Exchange Server 5.5 organization You can also upgrade Exchange Server 5.5 to Exchange 2000 Server and then to Exchange Server 2003 Duplicate accounts need to be merged; this is not straightforward because Exchange 5.5 mailboxes are not integrated with Active Directory user accounts ADC used to connect Exchange Server 5.5 to Active Directory Connection agreement required You can install Exchange Server 2003 into an existing Exchange Server 5.5 organization You can also upgrade Exchange Server 5.5 to Exchange 2000 Server and then to Exchange Server 2003 Duplicate accounts need to be merged; this is not straightforward because Exchange 5.5 mailboxes are not integrated with Active Directory user accounts
