Restart-ServiceEx.psm1

详细描述

利用WMI的Win32_Service类重启指定计算机上的服务.

Restart-ServiceEx cmdlet 通过WMI的Win32_Service类向指定计算机(ComputerName)的Windows服务控制器, 为每个指定的服务发送一个停止消息, 再接着发送一个启动消息. 如果服务已经停, 那么将会被直接启动. 你可以通过服务名称(Name)或显示名称(DisplayName)来指定需要重新启动的服务.

 

语法

 Restart-ServiceEx { [-Name] <string[]> | [-DisplayName] <string[]> } [-ComputerName] <string[]>

 

示例
