Step-by-Step Virtual Lab Setup (Windows Server 2025 + Windows 10) by Ryan Adams
I recently completed a hands-on Active Directory lab where I deployed Windows Server 2025 as a Domain Controller and connected Windows 10 client machines, all within a VirtualBox environment.
This lab provides a complete, step-by-step walkthrough for building a small-scale enterprise network in a secure virtual setup.
Installation of Windows Server 2025 and Windows 10
Configuration of DHCP, DNS, and NAT to enable full network communication
Promotion of the server to an Active Directory Domain Controller
Joining client machines to the domain
Validation of Group Policy, DHCP leases, and DNS name resolution
Configuration of Remote Access and NAT to provide internet access through the Domain Controller
Designing and implementing a structured IP addressing scheme
Understanding the core concepts of Active Directory, domains, and authentication
Troubleshooting domain join failures and network connectivity problems
Gaining insight into how centralized authentication is managed in enterprise networks
