SUMMARY

This article outlines how to set the maximum number of updated directory objects an Exchange Server bridgehead computer can send in one message when responding to a directory replication update request message.

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:

HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/MSExchangeDS/Parameters

Value: Intersite packet size

Data type: REG_WORD

Default: 512

Description: For a directory service acting as a bridgehead server, this key sets the maximum number of directory update objects the directory service can send in one message when it is responding to a directory replication update request message. If the local directory service has more than this number of objects, it tells the remote directory service (by means of a message) to request more objects.

IMPORTANT: Leave this value alone unless you have a specific requirement.
