Message Text

Process %1 (PID=%2). Exchange Active Directory Provider couldn't find any Global Catalog servers in either the local site '%3' or the following sites: %n%4

Explanation

Exchange Active Directory Provider found no global catalog servers in the local site or external sites. The sites are specified in the associated events. This can cause services startup failure or halting of mail flow. Therefore, it should be investigated immediately.

This may be caused by the following conditions:

  • All domain controllers are down or are not suitable
  • Network problems prevent the Exchange computer from contacting the domain controllers
  • Permission problems
  • Configuration errors

User Action

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

  • Verify that at least one global catalog exists in the forest and that it is reachable from the Exchange server on port 3268. If there are no global catalogs in the forest, use the Sites and Services MMC snap-in to promote a domain controller to a global catalog server.
  • Verify that DNS is configured correctly on the Exchange server and that the configured DNS servers are functional and reachable.
  • Use the nltest /dsgetdc: <domain> /site:<site name> command to verify that a global catalog server can be located in the specified sites. Look for the global catalog server flag in the nltest output. The NLTest tool is installed with the Windows support tools.
  • Suchen Sie im Anwendungsprotokoll nach verwandten Ereignissen. Die Details in weiteren MSExchange ADAccess-Ereignissen und anderen Ereignissen können dabei helfen, die Hauptursache für diese Warnung zu ermitteln. Erhöhen Sie den Diagnoseprotokolliergrad für die Kategorie "MSExchange ADAccess\Topologie" auf Niedrigste oder höher. Weitere Informationen zur Erhöhung des Protokolliergrads finden Sie unter Verwalten der Diagnoseprotokolliergrade.
  • If MSExchangeADAccess Event ID 2080 is logged, no suitable global catalogs may have been found when initial topology discovery was completed. Review that event to determine which domain controllers have been contacted and if they are unsuitable for any reasons. Correct any problems as indicated by the event description. For more information, see Microsoft Knowledge Base article 316300, Event ID 2080 from MSExchangeDSAccess.

If MSExchangeADAccess Event ID 2070 is logged, a global catalog may be down or is unreachable. Review the event for more information about why each domain controller is not suited. DSAccess found no suitable global catalogs when initial topology discovery was completed. Explanation

  • Verwenden Sie das Befehlszeilentool Ping oder PathPing zum Testen der grundlegenden Konnektivität. Verwenden Sie Ping, um Netzwerkhardwareprobleme und inkompatible Konfigurationen zu isolieren. Verwenden Sie PathPing, um Paketverluste bei Routen mit mehreren Hops zu ermitteln. Weitere Informationen finden Sie im Microsoft Knowledge Base-Artikel 325487 Behandlung von Problemen mit der Netzwerkverbindung.

For More Information

Wenn dies nicht bereits der Fall ist, sollten Sie die Exchange-Tools ausführen, die für die Analyse und Problembehandlung der Exchange-Umgebung erstellt wurden. Mit diesen Tools kann sichergestellt werden, dass Ihre Konfiguration die bewährten Methoden von Microsoft einhält. Sie tragen zudem zur Identifikation und zur Lösung von Leistungsproblemen bei, und können die Nachrichtenübermittlung verbessern. Sie können diese Tools über den Knoten Toolbox in der Exchange-Verwaltungskonsole ausführen. Weitere Informationen zu diesen Tools finden Sie unter Verwalten von Tools in der Toolbox.
