Message Text

Process %1 (PID=%2). Exchange Active Directory Provider received a request to connection to domain controller %3 but that domain controller is not available. Use the Ping or PathPing command-line tools to test network connectivity to local domain controllers. Run the Dcdiag command line tool to test domain controller health.

Explanation

This Error event indicates that the domain controller specified in the event description is not working or not reachable. The Active Directory provider maintains a pool of connections to the available domain controllers. Any Exchange process that has to access Active Directory uses an available connection from the connection pool. This event may occur if the connection in the connection pool indicates that the domain controller is not working or not reachable.

User Action

To resolve this error, do the following:

  1. Make sure that the domain controller is running and operational. Do one or more of the following:

    • Review the Application log for MSExchangeADAccess Event ID 2150. Event ID 2150 provides more information about the available domain controllers, global catalog servers, and configuration domain controllers in the Active Directory provider connection pool.

    • 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

    • 运行 Dcdiag 命令行工具可测试域控制器的运行状况。为此,请在 Exchange 服务器上的命令提示符处运行 dcdiag /s:[域控制器名称]。查看 Dcdiag 的输出,找出其报告的任何失败或警告的根本原因。有关详细信息,请参阅位于 Windows Server TechCenter 的 Dcdiag 概述

  2. After you make sure that the domain controller specified in the event description is running, restart the Active Directory topology service to rebuild the connection pool.

If this error persists, review the Application log and System log on the domain controller and Exchange server for any corresponding Warning or Error events.
