Details

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.

• 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, 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

• 使用 Ping 或 PathPing 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。
