Windows Server Core as a domain controller

Windows Server Core as a domain controller

This post will describe the steps for setting up a Windows Server Core as a domain controller for an Active Directory (AD) domain. Why would you do that? Well, first and foremost, it’s very useful for a developer to have a dedicated AD Domain Controller running on Windows Server Core since it’s a much smaller and leaner operating system then the full blown Windows Server product. You’ll most likely also run your domain controller in a virtual environment such as Hyper-V or VMWare and Windows Core is much less demanding on your resources, let alone more secure since it has a much smaller attack surface area.

Steps:

Install Windows Server Core

Rename the computer

First determine the current computer name. The easiest way to do this is to type SET and copy the COMPUTERNAME value.

>netdom renamecomputer <CurrentComputerName> /NewName:<YourNewName>

Set the IP address to a static address

>netsh int ip set address “Local Area Connection” static 192.168.65.210 255.255.255.0 192.168.65.2 1

Set the DNS Server

>netsh interface ipv4 add dnsserver name=”Local Area Connection” address=192.168.65.2 index=1

Install the DNS Role

>start /w ocsetup DNS-Server-Core-Role

Create the new Domain

>dcpromo /unattend:c:\unattend.txt

Checking if Active Directory Domain Services binaries are installed…

And then it will continue setting up your domain and automatically reboot.
