SYMPTOMS
If a mixed mode organization contains sites that span multiple domains, or an Exchange 2000 organization contains multiple domain controllers within a domain, replication may not occur, even though Connection Agreements are configured. Microsoft Windows Event Viewer may display the following error message:
CAUSE
This behavior can occur if the Active Directory Connector (ADC) service cannot locate a global catalog server that is running in a domain in which Exchange 2000 Server is installed. The Microsoft Windows 2000 Server endpoint that is specified in the Connection Agreement for replication to another domain is not a global catalog server.
RESOLUTION
To resolve this behavior, install a global catalog server in every site that is running Exchange 2000.
STATUS
This behavior is by design.
MORE INFORMATION
For performance reasons, Microsoft strongly recommends that you make sure that any Windows 2000-based servers that you use as replication endpoints for Connection Agreements are global catalog servers. Directory Service Access first looks for a global catalog server in an Exchange 2000 site. The ADC Administrator program queries the Connection Agreement Windows 2000 Server endpoints and warns users when the endpoint is not a global catalog server. If the Windows 2000 Server endpoint is not a global catalog server, the ADC must search twice for the global catalog server when the ADC attempts to replicate objects in another domain. If the Windows 2000-based endpoint is a global catalog server, the ADC Administrator sends out a query only once.
