Explanation

This Warning event indicates that a configuration domain controller that was specified in the Windows registry was not found in the Sites container in Active Directory. The configuration domain controller is a single computer that DSAccess selects to read and write information in the configuration naming context in Active Directory. A configuration domain controller should be a domain controller or a global catalog server.

This event can occur if one or more of the following conditions are true:

• The Microsoft Exchange Active Directory Topology service cannot locate the domain that contains the DNS server.
• The Active Directory Topology service cannot find the DNS name.
• The Active Directory Topology service cannot find a writable Naming Context in Active Directory.
• The Windows registry is configured to use an incorrect value. For example, the registry key or server name is not spelled correctly.

User Action

If other Exchange services start without a problem, this warning can be ignored. However, we recommend that you resolve this warning by doing one or more of the following:

• Make sure that the registry key and the configuration domain controller name are specified correctly in the Windows registry. This registry value is located as follows:
  HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeADAccess\Instance0\ConfigDCHostName

  Wichtig

  Create this registry key and specify a configuration domain controller name only if the automatically chosen domain controllers produce unwanted results. In such a case, find the problem, fix it, and delete the registry value so that the configuration domain controller is chosen automatically.

• Make sure that the configuration domain controller specified in the registry is registered correctly on the DNS server. For more information, see the following topics:

  • Troubleshooting Active Directory Related DNS Problems
  • DNS Support for Active Directory Tools and Settings

• In Active Directory Sites and Services, make sure that the configuration domain controller specified in the registry is listed under the Sites container.

• Check the Application log and the System log on the domain controller mentioned in the event description for any corresponding Warning or Error events.
