Synchronization interval for attributes flagged as Sync Never
30 minutes for NetWare 4; 60 minutes for NetWare 5 and higher and eDirectory servers
This chapter also examines several object-related and partitioning replication “ related operations to show how DS actually performs these operations. Understanding how these processes operate lays a foundation for understanding how to effectively troubleshoot and resolve problems. The next two parts of this book examine how to use this information to troubleshoot and resolve issues with NDS/eDirectory, using the different tools available. The following chapters also examine ways to combine tools using different techniques in order to streamline the troubleshooting-resolution process.
