| Event Information | According to Microsoft: EXPLANATION: This is an Active Directory internal event. Internal events appear in Event Viewer only when the default logging level is changed. Most internal events are for informational purposes only. This event is logged when Active Directory cannot perform an operation because the Active Directory database has run out of version storage. This is usually caused by a long-running transaction that prevents version store cleanup. USER ACTION: Determine whether there are any long-running transactions that are being held by the system, such as a long search operation. If a long-running transaction does exist, determine whether it is an inefficient search and then take appropriate action. |
