Two replication-related settings that you can customize for application partitions (or any naming context for that matter) include the first and subsequent replication delay after a change to the partition has been detected. The first replication delay is the time that a domain controller waits before it notifies its first replication partner that there has been a change. The subsequent replication delay is the time that the domain controller waits after it has notified its first replication partner before it will notify its next partner. You may need to customize these settings so that replication happens as quickly as you need it to for data in the application partition.

The Windows Server 2003 version of repadmin supports setting the notification delays:
> repadmin /notifyopt <AppPartitionDN> /first:<FirstDelayInSeconds> /subs:[RETURN] <NextDelayInSeconds>
For Windows 2000, you can create an LDIF file with the following contents:
dn: <AppPartitionCrossRefDN> changetype: modify replace: msDS-Replication-Notify-First-DSA-Delay msDS-Replication-Notify-First-DSA-Delay: <FirstDelayInSeconds> - replace: msDS-Replication-Notify-Subsequent-DSA-Delay msDS-Replication-Notify-Subsequent-DSA-Delay: <NextDelayInSeconds> -
If the file were named change_replication_delays.ldf, you'd run the following command:
> ldifde -v -i -f change_replication_delays.ldf

The settings that control the notification delay are stored in the msDS-Replication-Notify-First-DSA-Delay and msDS-Replication-Notify-Subsequent-DSA-Delay attributes on the application partition's crossRef object in the Partitions container. The time values are stored as seconds. The default for application partitions is 60 seconds for the first delay and 60 seconds for the subsequent delay.
