Server 2025 Core ADDS DC, Network Profile Showing as "Public" and not as "DomainAuthenticated"

Hi,

I've created this Workaround Script:

It will create a folder C:\install\scripts, put a fix script in it and schedule it to run at startup, the script will reset the adapter if in public profile

$scriptContent = @"
# FixPubFWProfile.ps1
# This script fixes the public network profile

# Get the network profiles
`$networkProfiles = Get-NetConnectionProfile

# Wait for 60 seconds
Start-Sleep -Seconds 60

# Loop through each profile and restart-adapter if it is set to public
foreach (`$Nprofile in `$networkProfiles) {
    if (`$Nprofile.NetworkCategory -eq "Public") { 
        Restart-NetAdapter -Name `$Nprofile.InterfaceAlias
    }
}
"@

$scriptPath = "c:\Install\Scripts\FixPubFWProfile.ps1"

# Create the directory if it doesn't exist
if (-not (Test-Path -Path (Split-Path -Path $scriptPath))) {
    New-Item -ItemType Directory -Path (Split-Path -Path $scriptPath) -Force
}

# Write the script content to the file
Set-Content -Path $scriptPath -Value $scriptContent

Write-Output "Script created at $scriptPath"

$action = New-ScheduledTaskAction -Execute "powershell.exe" -Argument "-ExecutionPolicy Bypass -NoProfile -File `"$scriptPath`""
$trigger = New-ScheduledTaskTrigger -AtStartup
$principal = New-ScheduledTaskPrincipal -UserId "SYSTEM" -LogonType ServiceAccount -RunLevel Highest
$settings = New-ScheduledTaskSettingsSet -AllowStartIfOnBatteries -DontStopIfGoingOnBatteries -StartWhenAvailable

#check if the task already exists
$taskExists = Get-ScheduledTask -TaskName "FixPublicNetworkProfile" -ErrorAction SilentlyContinue
if ($taskExists) {
    Write-Output "Scheduled task 'FixPublicNetworkProfile' already exists"
}
else {
    Register-ScheduledTask -Action $action -Trigger $trigger -Principal $principal -Settings $settings -TaskName "FixPublicNetworkProfile" -Description "Fixes the public network profile 1 minute after startup"
    Write-Output "Scheduled task 'FixPublicNetworkProfile' created to run at startup with a 1 minute delay in the script"
}
