Getting Our Hands Dirty

1. AD Administrator Guided Lab Part I

In this section, we will serve as domain administrators to Inlanefreight for a day. We have been tasked to help the IT department close some work orders, so we will perform actions such as adding and removing users and groups, managing group policies, and more. Successful completion of the tasks can lead to us gaining promotion to the Tier II IT team from the helpdesk.

For this lab, you will have access to a domain-joined Windows server from which you can perform any actions needed to complete the lab. The environment will require you to RDP from Pwnbox or your own VM over VPN to the Windows server. Follow the steps below to utilize RDP and connect to the lab’s Windows host.

We can connect via OpenVPN. And Click the Target to Spawn the target System.

We can get a connection to the Windows server via RDP.

RDP connection

After this HTB Academy, Instructions are enough, So, I Will Leave the Tasks from here.

2. AD Administrator Guided Lab Part II

I Hope, You guys like the Module and this write-up. This module is very useful for beginners. All the things that you needed to start an active directory are enough. As an experienced professional, I felt little laziness in this module. But if I would be starting, It’s the best thing to start with.

And Additionally, TCM security AD build is also can teach you a lot. As you will be creating your own AD. As I have done the PEH course in 2021.

Thanks, Mates. See you guys in the Next Module X).
