需求：
主域控制器出現災難故障，輔助域控制器正常
在輔助域控制器使用ntdsutil工具清理主域控制器並奪取PDC角色
首先清理孤立的域控制器
ntdsutil ntdsutil: metadata cleanup metadata cleanup: select operation target select operation target: connections server connections: connect to domain 3b.net #登陸到本地域 server connections:quit select operation target: list sites select operation target: List domains in site select operation target: select domain 0 select operation target: select server 0 select operation target: quit metadata cleanup:Remove selected server #刪除一個域控制器 metadata cleanup:quit ntdsutil: quit
輔助域控制需要奪取五種ＦＭＳＯ成為主域控制器
ntdsutil ntdsutil: metadata cleanup metadata cleanup: select operation target select operation target: connections server connections: connect to domain 3b.net #登陸到本地域 server connections:quit select operation target: list sites select operation target: List domains in site select operation target: select domain 0 select operation target: select server 0 select operation target: quit ##奪取角色 fsmo maintenance:Seize domain naming master fsmo maintenance:Seize infrastructure master fsmo maintenance:Seize PDC fsmo maintenance:Seize RID master fsmo maintenance:Seize schema master fsmo maintenance:quit ntdsutil: quit
