WMI實現遠端監控多臺windows伺服器
簡介
WMI簡介：
WMI（Windows Management Instrumentation,Windows 管理規範）是一項核心的 Windows 管理技術；使用者可以使用 WMI 管理本地和遠端計算機。
WQL簡介：
WQL就是WMI中的查詢語言，WQL的全稱是WMI Query Language，簡稱為WQL，翻譯成中文好像可以成為Windows管理規範查詢語言。熟悉SQL語言的朋友會感覺它和SQL非常相似。
WQL其實非常簡單，它有如下特點：
1、每個WQL語句必須以SELECT開始；
2、SELECT後跟你需要查詢的屬性名（我剛才對應SQL將其稱之為欄位名了），也可以像SQL一樣，以*表示返回所有屬性值；
3、FROM關鍵字；
4、你要查詢的類的名字；
5、另外，如果你想精確查詢結果還可以加上WHERE條件從句。比如某個類有Enable屬性，你可以在查詢的時候加上WHERE ENABLE=true，條件可以新增and or等關係操作。
如以下的都是正確的WQL語句：
Select * From Win32_LogicalDisk where drivetype=3 ’‘’‘查詢所有硬碟分割槽
SELECT * FROM Win32_share ’‘查詢所有共享目錄
SELECT * FROM Win32_NetworkAdapterConfiguration WHERE DHCPEnabled=TRUE
SELECT Description FROM Win32_Account WHERE Name='Administrator'
SELECT Freespace,DeviceID FROM Win32_LogicalDisk
在搜尋框輸入wbemtest即可檢視WQL測試工具

1、環境準備
a、windows要開啟Remote Registry與Windows Management Instrumentation服務
b、禁用放火牆
c、window2008系統登錄檔越獄（高版本的win）
需要修改regedit中HKEY_CLASSES_ROOT\CLSID\{76A64158-CB41-11D1-8B02-00600806D9B6}的許可權，windows2008不再給Administrators完全控制權。
http://files.helgeklein.com/downloads/SetACL/current/SetACL%20(executable%20version).zip
set_wmi_reg_acl.cmd
SetACL.exe -on "HKEY_CLASSES_ROOT\CLSID\{76A64158-CB41-11D1-8B02-00600806D9B6}" -ot reg -actn setowner -ownr "n:Administrators"
SetACL.exe -on "HKEY_CLASSES_ROOT\CLSID\{76A64158-CB41-11D1-8B02-00600806D9B6}" -ot reg -actn ace -ace "n:Administrators;p:full"
以超級管理員身份執行這個cmd，就會把owner與完全控制權限授予Administrators組
注意這裡需要把這個cmd命令和SetACL.exe copy到C:\Windows\System32資料夾
