查找所有 DHCP 和 DNS 服务器 [英] Finding All DHCP and DNS servers

问题描述

我有一个客户让我找到他所有的 Dhcp 和 DNS 服务器以及一些额外的信息，比如 DC 服务器和操作系统所以我决定尝试提高我的 powershell 技能，但我还是新手，所以我写了这个脚本，但我想仍然缺少一些东西，因为它不起作用

I got a client who asked me to find all of his Dhcp and DNS servers with some additional info like DC servers and operationsystem so i decided to try sharpen my powershell skills but im still new to this so i wrote this script but i guess something is still missing because it doesnt work

我设法找到了一种方法来获取我想要的操作系统信息，但它让我回到了公司中的所有服务器

i managed to find a way to get the info i want which is the OS but it gets me back ALL the servers in the company

$servers = get-dhcpserverindc
   foreach($server in $Servers){
get-adcomputer -filter {Operatinsytem -like "*windows server*"} -properties 
Operatingsystem | sort name | format-table name,Operatinsytem

}

推荐答案

这并不太棘手.首先，您连接到安装了 RSAT 工具的机器，例如管理服务器、跳转盒或域控制器，并获取所有 DHCP 服务器的列表.

This is not too tricky. First off, you connect to a machine with the RSAT Tools installed, like an admin server, jump box, or Domain Controller, and get a list of all DHCP Servers.

$DHCPServers = Get-DhcpServerInDC

然后我们使用 PowerShell 的内置循环逻辑来遍历每个服务器，并检查您需要的操作系统信息.

Then we use PowerShell's built in looping logic to step through each server, and check for the OS info you need.

ForEach ($DHCPServer in $DHCPServers){
   $OSInfo = Get-CIMInstance -ComputerName $DHCPServer.DnsName -ClassName Win32_OperatingSystem
}

最后，我们将修改上面的内容以返回您要查找的信息，即 IP 地址、名称和操作系统版本

Finally, we'll modify this above to return the info you're looking for, namely the IP Address, Name, and OS Version

ForEach ($DHCPServer in $DHCPServers){
   $OSInfo = Get-CIMInstance -ComputerName $DHCPServer.DnsName -ClassName Win32_OperatingSystem
   [pscustomobject]@{
      ServerName = $DHCPServer.DnsName;
      IPAddress=$DHCPServer.IpAddress;
      OS=$OSInfo.Caption
    }
}

ServerName IPAddress    OS                                    
---------- ---------    --                                    
dc2016     192.168.10.1 Microsoft Windows Server 2016 Standard

从那里，您可以将其存储在变量中，将其制作为电子表格，执行您需要执行的任何操作.

From there, you can store it in a variable, make it a spreadsheet, do whatever you need to do.

希望这会有所帮助.

如果这不起作用，请确保您已先启用 PowerShell 远程处理.

If this isn't working, make sure you have enabled PowerShell Remoting first.
