Introduction
As Realm Labs grew, managing individual computers and devices manually became more difficult.
Installing applications, changing settings and keeping systems consistent across multiple machines quickly becomes repetitive.
The solution was to introduce a proper domain environment using Active Directory.
While Active Directory is usually associated with business environments, a home lab is the perfect place to learn how these technologies work and experiment safely.
Why Run Active Directory at Home?
A domain environment provides centralised management instead of configuring every device individually.
The benefits include:
- Central user management
- Computer organisation
- Security policies
- Automated configuration
- Consistent settings across devices
It also creates a realistic environment for learning enterprise administration.
The Domain Controller
The domain controller acts as the central authority for the network.
It provides several important services:
Authentication
Users can sign into multiple devices using a single account.
DNS
Active Directory relies heavily on DNS to allow devices and services to find each other.
Group Policy
Settings can be deployed centrally across computers.
Device Management
Computers can be organised and controlled from one location.
Organising the Environment
A well-planned Active Directory structure makes management much easier.
The lab uses organisational units (OUs) to separate different types of devices.
Example:
ORDER.REALM
├── Users
│
├── Computers
│
├── OlderPCs
│
├── VirtualMachines
│
└── Test Devices
This allows different policies to be applied depending on the purpose of each device.
Group Policy Management
One of the biggest advantages of Active Directory is Group Policy.
Instead of manually changing settings on every computer, policies can be applied centrally.
Examples include:
- Desktop settings
- Security options
- Drive mappings
- Login behaviour
- System restrictions
- User environment settings
This turns a collection of computers into a managed environment.
Synology Integration
Storage is an important part of the domain environment.
The Synology NAS provides:
- Shared folders
- Network storage
- Backup locations
- Centralised data access
Combining Active Directory with network storage creates a more realistic enterprise-style environment.
Challenges Along the Way
Building a domain at home has many of the same challenges found in professional environments.
Some examples:
- Incorrect DNS settings causing login issues
- Group Policies not applying as expected
- User and computer placement affecting policies
- Troubleshooting slow sign-in times
These problems are frustrating at the time, but they provide valuable learning opportunities.
Future Improvements
The domain environment will continue to evolve.
Future plans include:
- More automated deployments
- Additional Group Policies
- Improved monitoring
- Better backup and recovery testing
- More test environments
Conclusion
Creating a home domain transformed Realm Labs from a collection of connected computers into a properly managed environment.
Active Directory provides the foundation for experimenting with enterprise technologies while keeping the flexibility of a personal lab.
The goal isn’t just to run services — it’s to understand how they work and document the journey.
