Message Text

Process %1 (PID=%2). Exchange Active Directory Provider failed to obtain an IP address for DS server %3, error %4 (%5). This host will not be used as a DS server by Exchange Active Directory Provider.

Explanation

This Error event indicates that the Active Directory Provider did not obtain an IP address for an Active Directory server. This host will not be used as an Active Directory server by DSAccess. This could be caused by network problems. This is a critical error if there are no other domain controllers available.

User Action

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

  • Check the Application log for related events. The detail in other MSExchange ADAccess events and other events may help determine the root cause of this warning. Increase diagnostic logging for the MSExchange ADAccess\Topology category to Lowest or higher. For detailed information about how to increase logging, see Manage Diagnostic Logging Levels.

  • 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.
