使用Powershell获取DHCP客户端信息

Question

是否可以使用Powershell在庞大的DHCP服务器和作用域列表中找到DHCP客户端？

我在一家医院工作，医院有多个DHCP服务器(每个区域一个)，有多个作用域(每个服务器的DHCP范围超过50个)。我试图找到一种方法，可以编写一个Powershell脚本来筛选所有服务器和作用域，并返回我的(手动)服务器退役过程所需的相关信息，而不必手动完成此操作。

我们确实有应用程序和工具(太阳风)，可以为我提供我所需要的信息，但这既费时又费时，我宁愿让这个Powershell脚本--一个“一站式商店”脚本来收集我的信息并清理DHCP库存。并最终将其放入整个端到端的进程中，以便对服务器进行退役。我的梦想是能够运行一个脚本，给它一个服务器名，并让进程贯穿并清除从DHCP到DNS到AD用户和计算机的所有内容。但我现在就从小开始。
