Question

在发布此问题之前，我已经检查了许多其他类似的问题，但是这些问题的答案并没有帮助我，因此请尝试我的特定问题。

我有一个脚本，该脚本在PowerShell控制台中运行时有效，但在按计划任务运行时却不起作用。该脚本（请参见下文）执行以下操作：

获取自指定调度任务的上次运行以来目标计算机上的事件日志。检查是否指定了任何事件ID⇒如果没有，则不执行任何操作 ⇒如果找到该事件ID中的1个或多个，则重新启动机器。然后，它会检查指定的URL是否有200响应，并在经过指定的尝试次数后是否警告该URL没有给出200响应。

似乎失败的地方是远程事件日志的返回-当作为任务运行时，它什么也没回来，因此脚本决定不需要重新启动并且什么也不做。

在控制台运行和任务计划程序运行之间，帐户运行以及源计算机和目标计算机都是相同的。

从任务计划程序运行时，PowerShell脚本逻辑不起作用
