The knowledge consistency check did not correct directory inconsistencies. Be sure the directory service is running, and then try again. If the error recurs, try stopping the directory service and the Administrator program and then restarting them. To view details of the error, see the application event log in the Windows Event Viewer on the Microsoft Exchange Server computer on which you checked knowledge consistency.
