移除无效的域控制器(ADDS)Script

Posted 2020-10-21

移除无效的域控制器(ADDS)SCript(二)
我们上一篇介绍了使用命令行移除无效的域控制器(DC)操作，今天我们主要介绍使用VBS脚本来移除无效的域控制器，我们上一篇已经把DC2给删除了，所以我们为了测试，重新将一台服务器提升为域控制器，其实用脚本操作的过程是一样的，只是把操作过程写成了脚本而已；具体见下：

我们首先查看Domain Controller列表

我们准备好脚本

wscript.quit 

保存好脚本的扩展名为.vbs，然后保存在DC上，我们双击打开，会显示我们当前环境内所有的DC的hostname

因为我们要删除AO2，所以我们输入AO2名称，确认即可

如果我们输入的名称在AD中不存在就会提示一下信息

提示确认AO2是否需要删除，确认即可

删除完成

删除后，我们还是同样需要检查DNS、Sites中的遗留信息，具体可以参考上一篇文章中的介绍。
