Explanation

This event indicates that an error occurred that caused the Exchange Active Directory Provider to close a connection to the domain controller. The connection has to be closed and then reopened. However, the target domain controller may not be experiencing problems.

User Action

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

• Review the error code that is specified in the event description.

• Review the Application log for associated events.

• 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 workstations.

• 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 Overview at the Windows Server TechCenter.
