Explanation

This Warning event indicates that a search request that was sent to the server that is running Active Directory did not provide a result within a reasonable time period. The search request was abandoned. This event is logged when the search request to the directory service did not return in less than 120 seconds.

The most frequent cause of this warning is because the domain controller is under heavy stress. This warning may also be caused if a network error is introduced at the packet level. This causes the domain controller to continuously try to resend the requested information to Microsoft Exchange.

User Action

If this event is seen rarely, it can be ignored. If this Warning event is logged at specific times or if any other pattern is detected, do the following:

• Investigate what is occurring on the specific domain controller named in the Description section of the event and check to see whether it is being heavily loaded.

• 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。
