SUMMARY

This article describes how to set the maximum number of updated objects the local directory service can send in one remote procedure call (RPC) response when it is responding to a directory replication update request.

MORE INFORMATION

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.

The registry parameters that control how the directory service process works are found under the following registry key:

HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/MSExchangeDS/Parameters

Value: Replicator intra site packet size
Data type: REG_DWORD
Default: 100

If the local directory service has more than this number of objects, it informs the remote directory service (by means of direct RPC) to request more objects. This acts as a checkpoint and ensures that the communication link is still valid.

IMPORTANT: Leave this value at the default setting unless you have a specific purpose for changing it.
