Windows Server 2022 Home Lab — AD DS, DNS, CA and Secured RDP

Thu, 02 Apr 2026 00:00:00 +0000

This article describes the full setup of a two-server Windows Server 2022 home lab in Proxmox VE. Together the two virtual machines provide Active Directory Domain Services, DNS, Group Policy and a Certificate Authority (ADCS). RDP connections are secured with PKI certificates so that the Mac Mini M1 management workstation connects without certificate warnings.

This is part 3 of the series on building a Windows DevOps lab in Proxmox. In part 1 I described how to create a VM, and in part 2 how to prepare the template.

Proxmox Lab — Windows Server 2022 Template Preparation

Tue, 31 Mar 2026 10:00:00 +0100

This guide covers the complete process of preparing a freshly installed Windows Server 2022 VM as a reusable Proxmox template. All future VMs (CA server, member servers, etc.) are cloned from this template, saving significant time and ensuring a consistent baseline across the entire lab.

📄 Download the full guide with screenshots: WS2022-in-Proxmox-Template-Preparation-Guide.docx

Overview

The full process consists of these steps:

Install VirtIO guest drivers
Run Windows Update — fully patch the OS
Apply performance tweaks
Basic housekeeping — timezone, RDP, IE Enhanced Security
Sysprep — generalize and shut down
Convert to template in Proxmox

Warning: Never boot the VM after Sysprep. If you do, the generalization is consumed and the template must be rebuilt from scratch.
