|Adlb.exe - Active Directory Load Balancing Tool
The Active Directory Load Balancing (ADLB) rebalances the load each time a change occurs in your site topology or in the number of domain controllers you have. ADLB can stagger schedules so that the outbound replication load for each domain controller is spread out evenly. Good for balancing replication traffic between the Windows 2003 domain controllers when they are replicating to more than 20 other sites hosting the same domain.
