Rule Name

An error occurred when the Referral Interface called DSAccess to obtain a list of available global catalog servers.


This Error event indicates that the Microsoft Exchange System Attendant service failed to obtain a list of available global catalog servers from Active Directory. This event may be caused by network problems between the Exchange server and the configuration domain controllers it uses. Exchange will continue to use the global catalog servers of which it is currently aware.

User Action

To resolve this error, do one or more of the following:

  • Use the Netdiag tool to verify network connectivity between the Exchange server and the domain controllers it uses. For more information, see Netdiag.

  • Use the Dcdiag tool to verify that the Exchange server can communicate successfully with Active Directory. For more information, see Dcdiag.

  • Resolve your issue by using self-support options, assisted support options, and other resources. You can access these resources from the Exchange Server Solutions Center. From this page, click Self-Support Options in the navigation pane to use self-help options. Self-help options include searching the Microsoft Knowledge Base, posting a question at the Exchange Server forums, and others. Alternatively, in the navigation pane, you can click Assisted Support Options to contact a Microsoft support professional. Because your organization may have a specific procedure for directly contacting Microsoft Technical Support, be sure to review your organization's guidelines first.
