Sun Java System Identity Synchronization for Windows 6.0 Deployment Planning Guide

Changing the PDC FSMO Role Owner

This task is optional. If the Active Directory Connector in the failover installation is configured to communicate with a domain controller that does not have the PDC FSMO role, synchronization from Active Directory will be delayed due to the Active Directory replication latency. To avoid this delay, the PDC FSMO role can be transferred to the domain controller that the connector is accessing.
