How to Modify the Default Intra-Site Domain Controller Replication Interval (214678)

MORE INFORMATION

When a domain controller writes a change to its local copy of the Active 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 modify the delay between the change to the Active Directory and first replication partner notification, use Registry Editor to modify 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 is 0x12c, which in hexadecimal format is 300 decimal (5 minutes).

To modify the notification delay between domain controllers, use Registry Editor to modify 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 is 0x1e, which in hexadecimal format is 30 decimal (30 seconds).
