Message Text

Process %1 (PID=%2). Exchange Active Directory Provider could not find any domain controller servers in either the local site '%3' or the following sites: %n%4

Explanation

This event indicates that topology discovery determined that there are no suitable domain controllers in the local site or adjacent sites.

This can cause services startup failure or halting of mail flow and interruption of address book services. This problem should be investigated immediately.

This event may be logged if the following conditions are true:

  • Network connectivity issues may be preventing communication with the global catalog server.

  • The Exchange server may be pointing to the wrong DNS servers.

  • DNS may be configured incorrectly or the configured DNS servers may be down and not reachable.

  • Permission problems exist.

User Action

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

  • 查看应用程序日志中的相关事件。其他 MSExchange ADAccess 事件和其他事件中的详细信息可帮助确定出现此警告的根本原因。将 MSExchange ADAccess\Topology 类别的诊断日志记录增大到最低或更高。有关如何增加日志记录的详细信息,请参阅管理诊断日志记录级别

  • If MSExchangeADAccess Event ID 2080 is logged, suitable global catalogs may not be present when initial topology discovery completes. Review that event to determine which domain controllers have been contacted and if they are not suitable 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, global catalog may be down or is unreachable. Review the event for more information about why each domain controller is not suitable. ADAccess found no suitable global catalogs when initial topology discovery was completed.

  • 使用 PingPathPing 命令行工具测试基本连接。使用 Ping 可隔离网络硬件问题和不兼容配置。使用 PathPing 可检测多重跳跃行程中的数据包丢失。有关详细信息,请参阅 Microsoft 知识库文章 325487:Windows 工作站的高级网络适配器疑难解答
