-To refine our discussion into a final draft for setting up an Active Directory (AD) domain `homelab.local` for your home, including a detailed cybersecurity lab and efficient management of your home network, NAS, laptops, and other IT equipment, we'll structure the guide with precise steps and configurations.
+Certainly! Here's the updated reference guide for setting up your `homelab.local` Active Directory domain:

 ### Step 1: Domain and Controller Setup
 
 1. **Primary Domain Controller (PDC):** Choose a dedicated or virtual server with sufficient resources to run Windows Server. This server will manage the `homelab.local` domain.

 2. **Secondary Domain Controller (SDC):** Optional but recommended for redundancy. Can be less resource-intensive and also runs Windows Server.

 2. **Create User Accounts:**
    - Setup `Admin Account(s)` for AD and resource management.
    - Create individual `Family User Accounts` and `Guest Accounts` as needed.
+   - Use a clear naming convention for user accounts, e.g., `john.doe_001`.

 2. **Implement Firewall Rules:**
    - Control traffic between network segments, especially protecting `CyberLab` resources.
+   - Create specific firewall rules for each sub-OU within the `CyberLab`.
 
 ### Step 5: NAS Configuration and Access
 
 1. **Set Up Storage Areas:**
    - Allocate `Media`, `Personal Storage`, and `Lab Data` areas within the NAS, setting appropriate access permissions for each user or group.
 
+2. **NAS Backup Strategy:**
+   - Implement a separate backup strategy for the NAS, including regular incremental backups to an external drive or cloud storage service.

 ### Step 6: Group Policy Objects (GPOs)
 
 1. **Define Key Policies:**
-   - Enforce a strong `Password Policy`.
+   - Enforce a strong `Password Policy`, with a stricter policy for the `LabAdmins` group.
    - Set an `Update Policy` for automatic Windows updates.
-   - Apply `Software Restrictions` to limit installations on personal and home devices.
+   - Apply `Software Restrictions` to limit installations on personal and home devices, using a whitelist of approved software.
