Windows LAPS & Intune Are Great, But They Won't Tell You Why That Server Crashed at 3 AM

There is a significant shift happening in Windows security management. As highlighted in a recent 4sysops article, Microsoft has integrated the Local Administrator Password Solution (LAPS) directly into the OS, allowing administrators to manage local account password rotations via Microsoft Intune. This is a massive win for security hygiene—automating the rotation of unique passwords for local admins and escrowing them into Entra ID is exactly what we need to stop lateral movement in breach scenarios.

But for the Sysadmin or MSP technician staring at a dashboard at 2:00 AM, this introduces a new layer of operational complexity. While your security posture is getting tighter, your visibility into the actual state of those devices is often getting murkier.

The Problem: Configuration Drift and the "Black Hole" of Reboots

The article correctly points out that to leverage LAPS with Intune, you must enable the feature at the tenant level and deploy a policy defining backup directories and password complexity. This is a configuration change. In many environments, configuration changes are treated separately from patch management, which is treated separately from monitoring.

This is where the pain starts.

You deploy the LAPS policy via Intune. That policy might trigger a reboot, or it might run alongside your monthly "Patch Tuesday" updates. Now, consider the typical fragmented stack:

Intune manages the MDM policy and LAPS passwords.
Your RMM (like Ninja or Datto) pushes the Windows Updates.
Your Monitoring Tool (like SolarWinds or Zabbix) watches uptime.

When you push a critical security update that forces a reboot, the RMM often marks the task as "Success" as soon as the shutdown command is acknowledged. But what happens if the server hangs on the "Getting Windows ready" screen? Or what if the new LAPS password rotates, but your automated backup scripts fail because they were still cached the old credential?

In a siloed environment, you don't know there's a problem until:

A user tries to log in at 8:00 AM and fails.
Your backup job fails at midnight because it can't authenticate.
Your monitoring tool pings the IP, sees it's down, and sends a generic "Host Unreachable" email that gets buried in a noisy inbox.

You aren't managing IT; you're managing disjointed data points. The RMM says "Patched," Intune says "Compliant," but the server is effectively dead in the water.

How AlertMonitor Solves This

At AlertMonitor, we don't believe in silos. Patch management isn't just about pushing bits; it's about verifying the outcome. Our platform unifies infrastructure monitoring, RMM, and patching into a single source of truth.

Here is how we handle the reality of modern Windows management:

Context-Aware Alerting: If a device reboots unexpectedly after an update, AlertMonitor doesn't just send a "Server Down" alert. We correlate the outage with the patch deployment history. You get an alert that says: "Server-X is offline. This occurred 5 minutes after the installation of KB5034441." That context turns a confusing emergency into a targeted rollback operation.

Real-Time Compliance Tracking: We track the patch status of every managed Windows device in real time. You can see exactly which machines are missing updates, which have failed patches, and—crucially for LAPS environments—which devices are pending a reboot. This visibility ensures that a password rotation or a security update never leaves a device in a limbo state.

Integrated Workflow: Because our helpdesk is integrated with our monitoring, the ticket created for the outage automatically attaches the patch logs and the diagnostic data. No more toggling between five tabs to figure out why the local admin password isn't working or why the server didn't come back up.

Practical Steps: Verifying Update Readiness

While you are rolling out LAPS and Intune policies, you need to ensure your underlying patch management is solid. Before you deploy a batch of updates that might conflict with new LAPS policies, use this PowerShell script to audit your environment for systems that are missing critical updates or have pending reboots.

This script checks for the "Reboot Pending" state—a common culprit for failed LAPS password renewals and update installations—and lists the last boot time.

PowerShell

<#
.SYNOPSIS
    Checks for Pending Reboot status and Last Boot Time.
.DESCRIPTION
    Use this to audit devices before deploying LAPS or Intune policies
    to ensure they are in a stable state.
#>

function Test-PendingReboot {
    $PendingReboot = $false
    
    # Check Component-Based Servicing
    if (Get-ChildItem "HKLM:\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing\RebootPending" -ErrorAction SilentlyContinue) {
        $PendingReboot = $true
    }
    
    # Check Windows Update Auto Update Client
    if (Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\RebootRequired" -ErrorAction SilentlyContinue) {
        $PendingReboot = $true
    }
    
    # Check Session Manager
    if (Get-ItemProperty "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager" -Name "PendingFileRenameOperations" -ErrorAction SilentlyContinue) {
        $PendingReboot = $true
    }

    return $PendingReboot
}

$ComputerName = $env:COMPUTERNAME
$LastBoot = (Get-CimInstance Win32_OperatingSystem).LastBootUpTime
$NeedsReboot = Test-PendingReboot

if ($NeedsReboot) {
    Write-Host "[WARNING] $ComputerName requires a reboot before proceeding with LAPS/Update policies." -ForegroundColor Red
} else {
    Write-Host "[OK] $ComputerName is in a stable state." -ForegroundColor Green
}

Write-Host "Last Boot Time: $LastBoot"

In AlertMonitor, you can deploy this script across your environment. If a node returns [WARNING], you can stage that device for a reboot before your maintenance window, ensuring your LAPS and Intune deployments hit stable targets.

Conclusion

Integrating Windows LAPS with Microsoft Intune is a smart move for security. But without a unified monitoring and patching strategy, you are flying blind. Don't let a security update or a password rotation turn into a network outage. Unify your stack, know your state, and stop learning about problems from your users.
