Troubleshooting the delivery of certificates provisioned by SCEP to devices in Microsoft Intune

  • Article

This article gives troubleshooting guidance to help you investigate delivery of certificates to devices when you use Simple Certificate Enrollment Protocol (SCEP) to provision certificates in Intune. After the Network Device Enrollment Service (NDES) server receives the requested certificate for a device from the certification authority (CA), it passes that certificate back to the device.

This article applies to the step 5 of the SCEP communication workflow; delivery of the certificate to the device that submitted the certificate request.

Review the certification authority

When the CA has issued the certificate, you'll see an entry similar to the following example on the CA:

Review the device

Android

For device administrator enrolled devices, you'll see a notification similar to the following image, which prompts you to install the certificate:

For Android Enterprise or Samsung Knox, the certificate installation is automatic, and silent.

To view an installed certificate on Android, use a third party certificate viewing app.

You can also review the devices OMADM log. Look for entries that resemble the following examples, which are logged when certificates install:

iOS/iPadOS

On the iOS/iPadOS or iPadOS device, you can view the certificate under the Device Management Profile. Drill down to see details for installed certificates.

You can also find entries that resemble the following in the iOS debug log:

Windows

On a Windows device, verify the certificate was delivered:

  • Run eventvwr.msc to open Event Viewer. Go to Applications and Services Logs > Microsoft > Windows > DeviceManagement-Enterprise-Diagnostic-Provider > Admin and look for Event 39. This Event should have a general description of: SCEP: Certificate installed successfully.

    Screenshot of event 39 in the Windows Application log.

To view the certificate on the device, run certmgr.msc to open the Certificates MMC and verify that the root and SCEP certificates are installed correctly on the device in the personal store:

  1. Go to Certificates (local Computer) > Trusted Root Certification Authorities > Certificates, and verify that the root certificate from your CA is present. The values for Issued To and Issued By will be the same.
  2. In the Certificates MMC, go to Certificates – Current User > Personal > Certificates, and verify the requested certificate is present, with Issued By equal to the name of the CA.

Troubleshoot failures

Android

To troubleshoot certificate delivery, review errors that are logged in the OMA DM log.

iOS/iPadOS

To troubleshoot certificate delivery, review errors that are logged in the devices debug log.

Windows

To troubleshoot issues with the certificate not being installed on the device, look in the Windows Event log for errors that suggest problems:

  • On the device, run eventvwr.msc to open Event Viewer, and then go to Applications and Services Logs > Microsoft > Windows > DeviceManagement-Enterprise-Diagnostic-Provider > Admin.

Errors with delivery and installation of the certificate to the device are typically related to Windows operations, and not to Intune.

Next steps

If the certificate successfully deploys to the device, but Intune doesn't report success, see NDES reporting to Intune to troubleshoot reporting.
