所以这是我想要做的事情的范围：
获取多个站点中 Windows 计算机的远程计算机信息，并将找到的信息写入 Active Directory 中每个计算机对象的 .Description 属性。如果脚本无法连接到远程计算机，请将该信息记录到文本文件中，并且不要对无法连接的计算机对象进行任何更改。
为了计算脚本运行的时间，我有第二个脚本来测量执行时间。
我将此设置作为计划任务运行第二个脚本（调用第一个脚本），该脚本通过 Windows 7 Pro 虚拟机上的批处理文件执行。
我的问题是，根据我在日志中看到的信息，我相信脚本可能会遇到内存问题。任何有关可能诊断根本原因的帮助将不胜感激。没有进一步的告别，这是我的两个脚本的代码以及奇怪的日志输出示例。
主脚本（脚本 1）：

第二个脚本：

Add-PSSnapin Quest.ActiveRoles.ADManagement -erroraction SilentlyContinue
$timeoutput = Measure-Command {\\myscriptcomputer\c$\Somefolder\PSScripts\WriteComputerDescriptions.ps1}
cd \\myscriptcomputer\c$\Somefolder\PSScripts\WriteComputerDescriptions
$scriptlog = get-childitem | sort creationtime | select -last 1

Add-Content c:\somefolder\PSScripts\WriteComputerDescriptions\$logname "`nExecution Time: $timeoutput"
Write-Host "Script complete!"
Start-sleep -s 3
exit
在我的环境 Active Directory 中的结果中，这对数百个对象有效，但这是我在日志文件中看到的示例：
无法连接电脑computer391 无法连接电脑computer392 无法连接电脑computer393 无法连接电脑computer394 䔊数畣楴汤吠浩㩥ㄠ㨱㘰㈺⸱㜵㤵㐰ഷ</p>
乱码文本的最后一行让我认为可能存在与内存相关的问题。如果我在计算机数量少得多的容器/OU 上运行我的脚本，我日志中的最后一行是一个时间，这是我通常所期望的。
如果任何经验丰富的 Powershell 专业人士可以在这里提供一些建议，我将非常感谢您的帮助。
谢谢！
