General troubleshooting

If you weren't able to identify the onboarded device in Microsoft Entra ID or in the Intune admin center, and didn't receive an error during the enrollment, checking the registry key Computer\\HKEY\_LOCAL\_MACHINE\\SOFTWARE\\Microsoft\\SenseCM\\EnrollmentStatus can provide additional troubleshooting information.

The following table lists errors and directions on what to try/check in order to address the error. Note that the list of errors isn't complete and is based on typical/common errors encountered by customers in the past:

Error Code Enrollment Status Administrator Actions
5-7, 9, 11-12, 26-33 General error The device was successfully onboarded to Microsoft Defender for Endpoint. However, there was an error in the security configuration management flow. This could be due to the device not meeting prerequisites for Microsoft Defender for Endpoint management channel. Running the Client Analyzer on the device can help identify the root cause of the issue. If this doesn't help, contact support.
8, 44 Microsoft Intune Configuration issue The device was successfully onboarded to Microsoft Defender for Endpoint. However, Microsoft Intune hasn't been configured through the Admin Center to allow Microsoft Defender for Endpoint Security Configuration. Make sure the Microsoft Intune tenant is configured and the feature is turned on.
13-14,20,24,25 Connectivity issue The device was successfully onboarded to Microsoft Defender for Endpoint. However, there was an error in the security configuration management flow, which could be due to a connectivity issue. Verify that the Microsoft Entra ID and Microsoft Intune endpoints are opened in your firewall.
10,42 General Hybrid join failure The device was successfully onboarded to Microsoft Defender for Endpoint. However, there was an error in the security configuration management flow and the OS failed to perform hybrid join. Use Troubleshoot Microsoft Entra hybrid joined devices for troubleshooting OS-level hybrid join failures.
15 Tenant mismatch The device was successfully onboarded to Microsoft Defender for Endpoint. However, there was an error in the security configuration management flow because your Microsoft Defender for Endpoint tenant ID doesn't match your Microsoft Entra tenant ID. Make sure that the Microsoft Entra tenant ID from your Defender for Endpoint tenant matches the tenant ID in the SCP entry of your domain. For more details, Troubleshoot onboarding issues related to Security Management for Microsoft Defender for Endpoint.
16,17 Hybrid error - Service Connection Point The device was successfully onboarded to Microsoft Defender for Endpoint. However, Service Connection Point (SCP) record isn't configured correctly and the device couldn't be joined to Microsoft Entra ID. This could be due to the SCP being configured to join Enterprise DRS. Make sure the SCP record points to Microsoft Entra ID and SCP is configured following best practices. For more information, see Configure a service connection point.
18 Certificate error The device was successfully onboarded to Microsoft Defender for Endpoint. However, there was an error in the security configuration management flow due to a device certificate error. The device certificate belongs to a different tenant. Verify that best practices are followed when creating trusted certificate profiles.
36 , 37 Microsoft Entra Connect misconfiguration The device was successfully onboarded to Microsoft Defender for Endpoint. However, there was an error in the security configuration management flow due to a misconfiguration in Microsoft Entra Connect. To identify what is preventing the device from registering to Microsoft Entra ID, consider running the Device Registration Troubleshooter Tool. For Windows Server 2012 R2, run the dedicated troubleshooting instructions.
38,41 DNS error The device was successfully onboarded to Microsoft Defender for Endpoint. However, there was an error in the security configuration management flow due to a DNS error. Check the internet connection and/or DNS settings on the device. The invalid DNS settings might be on the workstation's side.
