When a domain controller writes a change to its local copy of the Active Directo...

Directory, a timer is started that determines when the domain controller's replication partners should be notified of the change. By default, this interval is 300 seconds (5 minutes). When this interval elapses, the domain controller initiates a notification to each intra-site replication partner that it has changes that need to be propagated. Another configurable parameter determines the number of seconds to pause between notification. This parameter prevents simultaneous replies by the replication partners. By default, this interval is 30 seconds. Both of these intervals can be modified by editing the registry.WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.To change the delay between the change to the Active Directory and first replication partner notification, use Registry Editor to change the value data for the "Replicator notify pause after modify (secs)" DWORD value in the following registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NTDS\Parameters The default value data for the "Replicator notify pause after modify (secs)" DWORD value in Windows 2000 is 0x12c. This hexadecimal format is equal to a decimal value of 300 that is equal to 5 minutes. In Windows Server 2003 and in later versions, the default value data is 15 seconds. To change the notification delay between domain controllers, use Registry Editor to change the value data for the "Replicator notify pause between DSAs (secs)" DWORD value in the following registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NTDS\Parameters The default value data for the "Replicator notify pause between DSAs (secs)" DWORD value in Windows 2000 is 0x1e. This hexadecimal format is equal to a decimal value of 30 that is equal to 30 seconds. The default value in Windows Server 2003 and in later versions is decreased to 3 seconds when the forest functional level is Windows Server 2003 or a higher functional level.Note A setting also applies to Active Directory Application Mode (ADAM) and Active Directory Lightweight Directory Services (AD LDS). For ADAM and for AD LDS, the registry key is in the ADAM instance "Parameters" registry key.
