起因：vm虛擬化下所有的服務器都是使用模板來新建虛擬機的，所以使得部分客戶端SID相同了。
現象：在wsus 3.0 sp1控制檯上，無法看到所有服務器客戶端。
解決方案：均在客戶端上操作，
net stop wuauserv
刪掉 HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdate 下面 SusClientId 和 SusClientIdValidation 鍵
刪掉Windows目錄下SoftwareDistribution文件夾
net start wuauserv
運行 wuauclt.exe /Detectnow /Resetauthorization 命令
在控制檯就可以看到新加入的客戶端了，基本上秒殺！
用於清除WSUS客戶端相同SID的代碼 如下：
