As I prepping this yesterday for a customer, which does work https://soeintunedevice.wixsite.com/home/post/181-microsoft-intune-prompt-for-hostname-change if you want to have a read.

Install.ps1 is as follows, to explain what it does is the "Prefix" is generally what you see in

Since there is no way to do this via Intune, the only way would be via PowerShell. It will start off with applying WIN11-3D-001 as the hostname


$Prefix = 'WIN11-3D-'
$regPath = "HKLM:\SOFTWARE\MrBSOEWay\RenameComputer"
$regValue = "Version"

# Check if rename already occurred
if (Test-Path $regPath) {
    Write-Output "Device already renamed. Skipping rename."
    exit
}

# Get list of existing devices from Intune registry (simulated local tracking)
$serialBase = 01
$serialFile = "$env:ProgramData\\MrBSOEWay\\serial.txt"
if (!(Test-Path $serialFile)) {
    New-Item -ItemType File -Path $serialFile -Force | Out-Null
    Set-Content -Path $serialFile -Value $serialBase
}

# Read and increment serial
$Serial = Get-Content -Path $serialFile
$NewSerial = [int]$Serial + 01
Set-Content -Path $serialFile -Value $NewSerial

# Construct new hostname
$NewComputername = $Prefix + $NewSerial.ToString("D3")
Write-Output "Renaming device to $NewComputername"
Rename-Computer -NewName $NewComputername -Force

# Create registry key for detection
New-Item -Path "Registry::HKEY_LOCAL_MACHINE\SOFTWARE\MrBSOEWay" -ErrorAction SilentlyContinue
New-Item -Path "Registry::HKEY_LOCAL_MACHINE\SOFTWARE\MrBSOEWay\RenameComputer" -ErrorAction SilentlyContinue
New-ItemProperty -Path "Registry::HKEY_LOCAL_MACHINE\SOFTWARE\MrBSOEWay\RenameComputer" -Name Version -Value "1.0" -PropertyType String -Force -ErrorAction SilentlyContinue

Restart-Computer

Detect.ps1:

$Path = "HKLM:\Software\MrBSOEWay\RenameComputer"
$Name = "Version"
$Type = "STRING"
$Value = "1.0"
 
Try {
    $Registry = Get-ItemProperty -Path $Path -Name $Name -ErrorAction Stop | Select-Object -ExpandProperty $Name
    If ($Registry -eq $Value){
        Write-Output "Detected"
       Exit 0
    } 

    Exit 1
} 

Catch {

    Exit 1
}

Current hostname is WIN11-3D-01
