A. The Knowledge Consistency Checker (KCC), which manages connection objects for inter- and intrasite replication, ascertains whether you need to create new objects or delete existing objects. The KCC runs every 15 minutes by default. The FAQ How do I change how often the Knowledge Consistency Checker runs? explains how to change this time period. To determine when the KCC starts and stops, start regedit and go to the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesNTDSDiagnostics Registry entry.
Double-click Knowledge Consistency Checker. Set the value to 3 or greater, and click OK. Close the Registry editor. You don’t need to restart the machine for the change to take effect.
A value of 3 or greater in Knowledge Consistency Checker causes the KCC to log extra events that you can use Event Viewer’s Directory Service branch to view. Some common events that are useful to view include
Event 1007 signifies the KCC starting.
Event 1009, as the Screen shows, signifies the beginning of the KCC check.
Event 1013 signifies the end of the KCC check.
Event 1015 signifies the KCC stopping.
Event 1133 provides information about the KCC check.
