Rule Name

DSAccess failed to register an Active Directory shutdown notification with the local server.


This Warning event occurs if the Exchange server is running on the only domain controller in the Active Directory topology and DSAccess does not register an Active Directory shutdown notification. An Active Directory shutdown notification causes Exchange Server services that depend on Active Directory to close the LDAP connection to Active Directory. The shutdown time of the Exchange server is minimized when Active Directory shutdown notification is successful.

This event may be caused for the following reasons:

  • Failure to establish a Lightweight Directory Access Protocol (LDAP) version 3 connection to the local server. For more information, see How Active Directory Searches Work.

  • Failure to determine the distinguished name of the NTDS Settings object of the local server.

This warning does not occur in topologies that include multiple domain controllers.
