Message Text

Process %1 (PID=%2). Error 0x%3 occurred when DNS was queried for the service location (SRV) resource record used to locate a domain controller for domain %4%n The query was for the SRV record for %5%n For information about correcting this problem, %6%7

Explanation

This event indicates that an error occurred when Domain Name System (DNS) was queried for service resource (SRV) records for the specified domain. The domain controllers from the specified domain will not be used by DSAccess. You should investigate the issue and fix it. As long as there is sufficient capacity in usable domain controllers in other domains, there will not be mail flow interruption. If the event contains the name of the local domain, topology discovery cannot be completed and mail flow will be interrupted.

This behavior may occur if the required resource records in DNS are missing or incorrect.

User Action

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

Verify that the required SRV and A resource records exist in DNS by using the Nslookup command-line tool. For more information about how to use Nslookup, see Microsoft Knowledge Base article 200525, Using NSlookup.exe.

  • Verify connectivity, and then verify that the domain controller is running.

  • 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。.

  • 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。.
