Explanation

This Error event indicates that all domain controllers in the Active Directory topology are either not working not reachable. This event may occur under the following conditions:

• Network issues have caused all domain controllers to become unreachable.

User Action

To resolve this problem, follow these steps:

• Review MSExchangeADAccess Event 2150 for a list of domain controllers, global catalog servers, and configuration domain controllers tat are available in the Active Directory topology. 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.
• Führen Sie das Befehlszeilentool Dcdiag aus, um den Domänencontrollerzustand zu testen. Führen Sie hierfür dcdiag /s:[Domänencontrollername] an einer Eingabeaufforderung des Exchange-Servers aus. Verwenden Sie die Ausgabe von Dcdiag, um die Hauptursache der gemeldeten Fehler oder Warnungen zu ermitteln. Weitere Informationen finden Sie unter Dcdiag im Überblick (möglicherweise in englischer Sprache) im Windows Server TechCenter.
• Make sure that Exchange Enterprise Servers and Exchange Servers security groups are added to Manage Auditing and to Security Log under Default Domain Controller Security Settings. To do this, follow these steps:
  1. In the Default Domain Controller Security Settings snap-in, expand Local Policies under Security Settings, and then click User Rights Assignment.
     In the right pane, right-click Manage Auditing and Security Log, and then click Properties.
  2. Make sure that the Define these policy settings check box is selected and that Exchange Enterprise Servers and Exchange Servers are listed beneath the check box.
• Überprüfen Sie das Anwendungsprotokoll und das Systemprotokoll auf den Exchange 2010-Servern auf verwandte Ereignisse. Ereignisse, die unmittelbar vor oder nach diesem Ereignis auftreten, können z. B. weitere Informationen zur eigentlichen Ursache dieses Fehlers zur Verfügung stellen.
