This Error event indicates that the Microsoft Exchange File Distribution service could not find the local server object in Active Directory to replicate a Unified Messaging dial plan. The File Distribution service is used to distribute offline address book files and Unified Messaging prompts. It also replicates Unified Messaging dial plans. Unified Messaging dial plans are an integral component of the Exchange Unified Messaging system. For more information about Unified Messaging dial plans, see Understanding Unified Messaging Dial Plans.

No user action is required. The File Distribution service will continue to try to complete the replication process at a one-hour interval. However, if this event occurs frequently, follow one or more of these steps:

• 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, Advanced network adapter troubleshooting for Windows workstation.
  
  
• 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 Microsoft Exchange server that is experiencing the event. Use the output of Dcdiag to discover the root cause of any failures or warnings that it reports. For more information, see DCDI A G.
  
  
• Review the Application log and System log on your Exchange 2010 servers for related events. For example, events that occur immediately before and after this event may provide more information about the root cause of this error.
  
  
• Review the Operations Console in Operations Manager for detailed information about the cause of this problem. For more information, see the "Introduction" section in this article.
  
  
• 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.
  
  

If you are not already doing so, consider running the Exchange tools created to help you analyze and troubleshoot your Exchange environment. These tools can help make sure that your configuration aligns with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. To run these tools, go to the Toolbox node of the Exchange Management Console. To learn more about these tools, see Managing Tools in the Toolbox.
