Table of Contents

Windows 10 auto-enrollment into Microsoft Intune is a crucial process for modern device management, allowing devices to automatically register with Intune upon joining Azure Active Directory (Azure AD) or becoming Hybrid Azure AD Joined. This seamless process enables IT administrators to manage device configurations, deploy applications, and enforce security policies without manual intervention. However, this process can sometimes fail, presenting various error codes that require investigation. One specific error code encountered during auto-enrollment is 80180002b. Understanding the potential causes and having a structured troubleshooting approach is essential for resolving this issue efficiently.

Error 80180002b typically indicates a problem during the Mobile Device Management (MDM) enrollment phase, specifically suggesting that the device is unable to proceed with enrollment after successfully registering with Azure AD. This can stem from several factors, ranging from incorrect Azure AD configurations to device-specific issues or policy conflicts. Resolving this error requires systematically checking the prerequisites for auto-enrollment and examining logs to pinpoint the exact failure point. This guide provides a comprehensive walkthrough of the common causes and steps to diagnose and fix error 80180002b, ensuring your Windows 10 devices can successfully auto-enroll into Intune.

Understanding Intune Auto-Enrollment Prerequisites¶

Before diving into troubleshooting error 80180002b, it’s critical to ensure that the foundational prerequisites for Windows 10 auto-enrollment are correctly configured in your Azure AD tenant. The auto-enrollment process depends on two primary conditions being met. First, the user attempting to enroll the device must have a valid license that includes the necessary Intune or EMS (Enterprise Mobility + Security) service. Second, the MDM user scope in Azure AD must be configured to include the user or group to which the user belongs. These two settings dictate which users are eligible for automatic MDM enrollment when they add their work or school account to a Windows 10 device or join it to Azure AD.

Azure AD Premium licenses (P1 or P2) are commonly required, as they include the necessary rights for MDM auto-enrollment. While some Microsoft 365 licenses also bundle Intune, confirming the specific license assigned to the user is a crucial first step. The MDM user scope, configured within Azure AD settings under Mobility (MDM and MAM), specifies which users’ devices should attempt auto-enrollment. This scope can be set to None, Some (requiring you to specify a group), or All. If the user is not covered by the configured scope (e.g., not in the specified group when set to Some), auto-enrollment will fail, potentially with error codes like 80180002b.

Common Causes of Error 80180002b¶

Error 80180002b is a generic enrollment error, meaning it can be triggered by several underlying issues during the MDM registration phase. Identifying the root cause is key to applying the correct fix. One primary reason is related to the Azure AD and MDM configuration. If the MDM user scope is incorrectly set or the user lacks the required license, the enrollment attempt will be rejected by the Intune service, resulting in this error. Another frequent cause involves device state and type. The auto-enrollment flow differs slightly for Azure AD Joined, Hybrid Azure AD Joined, and Azure AD Registered devices. Conflicts or misconfigurations during the join process can impact the subsequent MDM enrollment.

Furthermore, Group Policy Objects (GPOs) can significantly interfere with MDM enrollment, especially in Hybrid Azure AD Join scenarios. If a GPO is configured to specify an alternative MDM provider or block MDM enrollment entirely, it can prevent the Intune auto-enrollment from completing successfully. Network connectivity issues or restrictions imposed by firewalls can also block communication with Intune endpoints necessary for enrollment. Less common causes include time synchronization problems on the client device or Conditional Access policies that unintentionally block the enrollment process based on location, device state, or other conditions. Systematically investigating these potential areas is vital for successful troubleshooting.

Troubleshooting Guide: Step-by-Step Solutions¶

Troubleshooting error 80180002b requires a methodical approach, starting from the most common configuration issues and progressing to more complex potential problems. Follow these steps to diagnose and resolve the error.

Step 1: Verify Licensing and MDM Scope¶

The first and most critical step is to confirm that the user attempting to enroll the device meets the licensing and scope requirements in Azure AD. Without a proper license and inclusion in the MDM user scope, auto-enrollment cannot succeed.

Navigate to the Azure Active Directory admin center (aad.portal.azure.com) and verify that the user has an assigned license that includes Microsoft Intune or an EMS plan. Next, go to Azure Active Directory > Mobility (MDM and MAM). Click on Microsoft Intune and review the “MDM user scope” setting. Ensure it is set to All or, if set to Some, confirm that the user is a member of the specified Azure AD group. Make sure the “MDM Terms of Use URL” and “MDM Discovery URL” are correctly populated (they should point to https://enrollment.manage.microsoft.com/enrollmentserver/discovery.svc and https://portal.manage.microsoft.com/TermsOfUse.aspx respectively, by default). If any of these configurations are incorrect, adjust them and attempt the enrollment again on the client device.

Step 2: Check Device Azure AD Join State¶

The way a device is joined to Azure AD affects the auto-enrollment trigger. Error 80180002b can sometimes occur if the device’s Azure AD join state is ambiguous or incorrect.

Open a command prompt on the affected Windows 10 device and run dsregcmd /status. Examine the output, specifically the sections for AzureAdJoined and DomainJoined. For standard auto-enrollment, AzureAdJoined should be YES (for Azure AD Joined devices) or YES along with DomainJoined being YES (for Hybrid Azure AD Joined devices). AzureAdRegistered should ideally be NO for corporate-owned devices intended for full management via join. If the status is not as expected, there might be an issue with the initial Azure AD join process itself, which needs to be resolved before MDM auto-enrollment can succeed. Re-joining the device to Azure AD or the on-premises domain might be necessary in such cases.

Step 3: Examine Event Logs¶

Windows 10 provides detailed logging for device management activities, which is invaluable for pinpointing the exact cause of enrollment failures like error 80180002b. The most relevant log is the DeviceManagement-Enterprise-Diagnostics-Provider log.

On the client device, open the Event Viewer (eventvwr.msc). Navigate to Applications and Services Logs > Microsoft > Windows > DeviceManagement-Enterprise-Diagnostics-Provider > Admin. Look for events around the time the enrollment attempt failed. Search for events related to enrollment failures or errors matching 80180002b. The details within these log entries often provide a more specific reason for the failure, such as a specific policy rejection, a communication error, or a configuration issue. Analyzing these logs is crucial as they provide granular details that generic error codes do not.

Step 4: Look for Group Policy Conflicts (Hybrid Joined Scenarios)¶

In environments using Hybrid Azure AD Join, Group Policy can sometimes interfere with Intune MDM auto-enrollment. GPOs have settings that can control MDM enrollment behavior, and these can override the automatic process triggered by Azure AD.

Run gpresult /r from a command prompt on the Hybrid Azure AD Joined device to see applied Group Policies. Look for policies related to “MDM enrollment”. Specifically, check the setting “Enable automatic MDM enrollment using default Azure AD credentials”. This policy should be Not Configured or configured correctly to allow enrollment. If a conflicting GPO is applied, it needs to be identified and either disabled, updated, or filtered so it doesn’t apply to the affected device or user. Conflicting GPOs are a very common source of enrollment issues in hybrid environments.

Step 5: Review Network Configuration and Firewalls¶

Successful MDM enrollment requires the client device to communicate with Microsoft Intune endpoints over the internet. Network restrictions, proxy servers, or firewalls can block this communication.

Ensure that the device has unrestricted access to the necessary Intune and Azure AD endpoints. Microsoft provides documentation listing the required URLs and ports (typically HTTPS 443) for Intune communication. Verify that no local firewall rules, corporate firewalls, or proxy servers are blocking traffic to these endpoints. Temporarily disabling the Windows Firewall or testing connectivity from a less restricted network segment can help rule out network-related causes. If a proxy is in use, ensure it is correctly configured on the device and does not require user authentication that might fail during the automated enrollment process.

Step 6: Check Time Synchronization¶

Incorrect time and date settings on the client device can cause authentication and communication failures with cloud services like Azure AD and Intune. This is a less common cause but is easy to check.

Verify that the date, time, and time zone settings on the Windows 10 device are accurate and synchronized with a reliable time source, such as time.windows.com or a domain controller (in hybrid scenarios). Significant time drift can lead to certificate validation errors and other issues that prevent successful enrollment. Correct any discrepancies and attempt enrollment again.

Step 7: Evaluate Conditional Access Policies¶

Azure AD Conditional Access policies can be configured to block access to cloud applications based on various conditions. While typically aimed at resource access after enrollment, misconfigured policies could potentially interfere with the enrollment process itself if they target the “Microsoft Intune Enrollment” or “Microsoft Intune” cloud apps.

Review your Azure AD Conditional Access policies (aad.portal.azure.com > Azure Active Directory > Security > Conditional Access) to ensure none are inadvertently blocking the enrollment flow for the affected user or device type. Pay close attention to policies that enforce requirements like Multi-Factor Authentication (MFA), compliant device state, or approved client applications, especially if these policies are applied to the “Microsoft Intune Enrollment” or “Microsoft Intune” cloud applications and target the users experiencing the error. Temporarily excluding a test user from Conditional Access policies can help isolate this as the cause.

Step 8: Consider Device Reset or Re-enrollment Attempt¶

If the above steps do not resolve the issue, there might be a corrupted enrollment state on the device. In some cases, resetting the device or attempting to remove and re-add the work/school account might clear the underlying problem.

For Azure AD Joined or Hybrid Azure AD Joined devices, carefully consider if removing the device from Azure AD/Domain and re-joining it is feasible. This action should be taken with caution as it affects device state and policies. Alternatively, for personally owned devices where a work/school account is added (Azure AD Registered), try removing the account via Settings > Accounts > Access work or school and then adding it again. For corporate-owned devices experiencing persistent issues, a full Windows 10 reset (keeping files) or a clean installation might be necessary as a last resort to ensure a fresh enrollment attempt.
