如何在企业设置中向用户/机器发送通知？

Question

现状： 我创建了一个 powershell 脚本，它可以在屏幕的右下方绘制一个类似 toast 的通知。我唯一的问题是这只适用于本地计算机。如何使此通知显示在目标计算机上？只需在 Active Directory 中指定机器名称即可？

当然，我愿意接受其他建议。我目前正在阅读 SignalR，但我不确定如何让 SignalR 在本机桌面上工作，而不是通过网站。完美的情况是一个通知系统，可以在 Windows 10 中批量发送 toast 通知。

有什么想法吗？

这是我当前的脚本

Function ShowNotification
{
    [CmdletBinding()]
    param(
           [string] $Title,
           [string] $Message,
           [string] $Image,
           [string] $Hyperlink 
    )
    Add-Type -AssemblyName presentationframework, System.Windows.Forms

         $screenHeight = Get-WmiObject -Class Win32_DesktopMonitor | Select-Object ScreenHeight
         $screenWidth = Get-WmiObject -Class Win32_DesktopMonitor | Select-Object ScreenWidth

我很久以前写过以下内容（它适用于远程机器 - 在 toast 消息起作用之前，用户必须在机器上登录，但控制台是否被锁定并不重要 - 他们只是需要登录）。 （我不应该发布这个，因为主题启动者没有提供他/她自己的代码，但这次我会例外）。请记住，我在此脚本中有一个变量 $cred 未设置为参数（此变量包含管理员凭据，因为 Invoke-Command 连接到远程计算机）。

Function Invoke-ToastMessage
{
[CmdletBinding()]
    Param
        (
        [string]$Message,
        [string]$Notifier = "Administrators",
        [string]$ComputerName = $null
        )

[scriptblock]$ToastScriptRemote = {
$Message = $args[0]
$Notifier = $args[1]

    else {$ToastScriptLocal.Invoke()}
