如何在企業設置中向用戶/機器發送通知？

Question

當前情況： 我創建了一個powershell腳本，可以在屏幕右下方繪製類似敬酒的通知。我唯一的問題是，這隻適用於本地計算機。如何將此通知顯示在目標機器上？只需在Active Directory中指定機器名稱？

當然，我接受其他建議。我目前正在閱讀SignalR，但我不確定如何讓SignalR在本機桌面上工作，而不是通過網站。完美的情況將是一個通知系統，可以在Windows 10中大量發送Toast通知。

任何想法？

這裏是我當前的腳本

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

我下面的地久天長的時間前寫的（它的工作原理在遠程計算機上 - 用戶已經在機器上敬酒的消息工作之前簽署的，但控制檯是否被鎖定無關緊要 - 他們只需登錄即可）。 （我不應該發佈這個，因爲主題首發沒有提供他/她自己的代碼，但這次我會例外）。請記住，我在這個腳本中有一個變量$ cred，它沒有被設置爲一個參數（因爲Invoke-Command，這個變量包含了管理員憑證給遠程機器）。
