Description

Sets the maximum idle delay time between receiving a message and sending an acknowledgment to the source.

Idle time is the time during which no messages are sent on the session. It ensures that computers creating a session for a limited time only will get all acknowledgments possible during the session. This prevents unnecessary resending due to lost acknowledgments.

This entry does not exist in the registry by default. You can add it by using the registry editor Regedit.exe.
