Process %1 (PID=%2). Temporarily unable to connect to Active Directory to read configuration data for object %3 (%4). Will wait for %5 seconds and retry.

This Warning event indicates that there is no suitable Active Directory directory service server available to read the configuration data for the object specified in the event description. The Microsoft Exchange File Distribution service must read the configuration data from Active Directory to distribute offline address book and custom Unified Messaging prompts.

This event may occur because of intermittent network issues.

If this Warning event frequently occurs, follow these steps:

• Use the Ping or PathPing command-line tools to test basic connectivity with the domain controller. 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 the Microsoft Windows Server TechCenter article, Dcdiag Overview.

• Review other related events in the Application log and System log for Warning events and Error events. These related events may provide more information about the root cause of this Warning event.

This Warning event may be ignored if occurred during known network issues.

Note  If you are not already doing so, consider running the tools that Microsoft Exchange offers to help administrators analyze and troubleshoot their Exchange environment. These tools can help you make sure that your configuration is in line with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. Go to the Toolbox node of the Exchange Management Console to run these tools now. For more information about these tools, see Toolbox in the Exchange Server 2007 Help.
