Microsoft's Active Directory is the backbone of the corporate world. It simplifies the management of devices and users within a corporate environment.

In this room, we'll take a deep dive into the essential components of Active Directory and assume the role of the new IT admin at THM Inc. As our first task, we have been asked to create a new Active Directory child domain, join a server to the domain, and then review some of the existing controls and configurations in the parent domain. You will be provided with administrative credentials for all servers to perform these configuration changes and complete the tasks ahead.

Network Configuration

This room uses a network where you will create your very own Active Directory forest! If this is your first time using networks on TryHackMe, it is suggested that you complete the Network Room Guide first. As a recap, you can use either the AttackBox to connect to this network or download the network OVPN file from the network diagram as shown below:

If you are experiencing issues connecting to the network, please refer back to the debugging steps provided in the Network Guide Room. Your subnet range for this network room will be 192.168.10.0/24.
