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.https://www.vandenboom.icu/en/blog/2026-proxmox-windows-server-2022-template-preparation/Tue, 31 Mar 2026 10:00:00 +0100https://www.vandenboom.icu/en/blog/2026-proxmox-windows-server-2022-template-preparation/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.https://www.vandenboom.icu/en/blog/2024-powershell-computer-resource-monitor-script-with-cpu-percentage-and-advanced-memory-information/Thu, 04 Jan 2024 22:21:38 +0000https://www.vandenboom.icu/en/blog/2024-powershell-computer-resource-monitor-script-with-cpu-percentage-and-advanced-memory-information/PowerShell computer resource monitor script with cpu percentage and advanced memory information PowerShell Resource monitor $app="notepad" $ids = Get-Process $app | Select-Object -Property Id | ForEach-Object {$_.Id} $filedate = Get-Date -format "yyyy-MM-dd" #echo $pids foreach ($id in $ids) { $date = Get-Date -format "yyyy-MM-dd HH:mm:ss" # process CPU information $ProcessId = $id $Process = Get-WmiObject -Query "SELECT * FROM Win32_PerfFormattedData_PerfProc_Process WHERE IDProcess = $ProcessId" $usage = $Process.PercentProcessorTime # process Mem information $TotalMemory = (Get-CimInstance Win32_ComputerSystem).https://www.vandenboom.icu/en/blog/powershell-clean-memory/Mon, 13 Dec 2021 19:12:03 +0100https://www.vandenboom.icu/en/blog/powershell-clean-memory/Function Clean-Memory { Get-PSSession | Remove-PSSession [System.GC]::Collect() [GC]::Collect() [GC]::WaitForPendingFinalizers() Get-Variable | #Where-Object { $startupVariables -notcontains $_.Name } | ForEach-Object { try { Clear-Variable -Name "$($_.Name)" -Force -ErrorAction SilentlyContinue -WarningAction SilentlyContinue Remove-Variable -Name "$($_.Name)" -Force -Scope "global" -ErrorAction SilentlyContinue -WarningAction SilentlyContinue Remove-Variable -Name "$($_.Name)" -Force -ErrorAction SilentlyContinue -WarningAction SilentlyContinue #Write-Host "Variable '$($_.Name)' has been cleaned up." } catch [Exception] { if ($_.Name -notlike '') { Write-Host "An error has occured.
