PowerShell 遠端操控 server -2
繼上一篇 PowerShell 遠端操控 server，我又在嘗試於 Workgroup + Domain 的環境下，該如何使用遠端操作。
在說明設定之前，我想提及一個重要的觀念，也就是遠端操控到底是如何運作的 ?
這是我之前上蘇建榮老師的課所得知的知識，分享如下：
一、遠端管理
這是第一種方式，也是傳統的方式，使用 RPC 來進行。
ex: Get-WMIObject Win32_LogicalDisk –ComputerName <ServerName>
二、遠端執行
建議使用的方式，是透過 WinRM 服務進行。 其實原理就是，將命令傳給另一個 server 來執行。
ex: Invoke-Command …….
那我們該如何設定呢 ? 本篇先說明一種最簡單快速的方式 → 安裝 Server 完畢後，將 Administrator 設定同樣的密碼，就可以立即使用 。 (結束)
有沒有覺得很無言………….。雖說簡單，但是我們必須知道為什麼可以這麼做。
原因有二: (1) RPC 服務一定是被開啟的 (2) 防火牆預設是有針對 RPC 服務開啟的
被選擇的防火牆規則，即是可以使用遠端操控的關鍵之一，我們點右鍵按內容來看詳細資訊，即發現此規則，即為上一篇所提及的，是開啟 RPC 動態連接埠 + svhost.exe 這支程式。
不過這有個小細節要注意，就是這招只能使用在 administrator 的帳戶之下，就連加入 administrators 群組的帳戶一樣無法使用，如下圖：
如果要使用不同帳戶的話，必須增加 2 個設定：(可參考 Remote WMI to a Workgroup Server 2008 R2 這篇文章)
1、開啟遠端使用 com 元件
(1)
(2)
(3)
2、 WMI Control 的安全性設定
(1)
(2)
(3)
我設定完之後，測試無誤。但發現， powershell 的回應速度有變慢。
另外，如果是 Domain 、 WorkGroup 混用的環境中，也是同樣可以使用的，只要帳號密碼一樣、防火牆設定正確，即可使用。
