Rule Name

System Attendant reported an error when setting directory service notification.


This Error event indicates that Microsoft Exchange System Attendant service did not set a directory services (DS) notification with one of the Active Directory servers. A DS notification with Active Directory helps the System Attendant and Microsoft Exchange Information Store services to obtain updates from Active Directory about new recipient policies, protocols, and more.

User Action

To resolve this error, follow these steps:

  • Make sure that the Exchange server that logged this event can connect to a domain controller. For example, Use the Ping or PathPing command-line tools to test basic connectivity. Use Ping to isolate network hardware problems and incompatible configurations. Use PathPing to detect packet loss over multiple-hop trips. For more information, see Microsoft Knowledge Base article 325487, How to troubleshoot network connectivity problems.

  • Run the Dcdiag command line tool to test domain controller health. To do this, run dcdiag /s:<Domain Controller Name> at a command prompt on the Exchange server. Use the output of Dcdiag to discover the root cause of any failures or warnings that it reports. For more information, see Dcdiag.

  • Review other related Error and Warning events in the Application and System Logs. These related events may help you find the root cause of this error.

If you cannot resolve the error using the options suggested here and Microsoft Exchange System Attendant does not start, contact Microsoft Customer Support Services. For more information about how to contact support, visit Microsoft Help and Support.
