Message Text

Process %1 (PID=%2).

Explanation

This event indicates that Domain Name System (DNS) service (SRV) records for the specified domain controller cannot be found. This event is logged when diagnostic logging on the MSExchangeADAccess\Topology component is set to Minimum or higher.

The specified domain controller will not be used by ADAccess. As long as there is sufficient capacity in suitable domain controllers, there is no mail flow interruption. We recommend that you investigate the issue and fix it.

This event may be caused when the following conditions are true:

  • A DNS SRV resource record that is used by this computer contains incorrect root hints.

  • One or more of the zones listed in the error message do not include a delegation to its child zone.

See the event description for detailed information about the cause of this event.

User Action

To resolve this event, verify that the SRV resource record for the requested domain and service type exists in DNS. You can do this using the Dcdiag command line tool. 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。
