There are additional components on the device that the Microsoft Defender for Endpoint agent depends on to function properly. If there are no onboarding related errors in the Microsoft Defender for Endpoint agent event log, proceed with the following steps to ensure that the additional components are configured correctly.

Ensure the diagnostic data service is enabled

If the devices aren't reporting correctly, you might need to check that the Windows 10 diagnostic data service is set to automatically start and is running on the device. The service might have been disabled by other programs or user configuration changes.

First, you should check that the service is set to start automatically when Windows starts, then you should check that the service is currently running (and start it if it isn't).

Ensure the service is set to start

Use the command line to check the Windows 10 diagnostic data service startup type:

  1. Open an elevated command-line prompt on the device:

    a. Click Start, type cmd, and press Enter.

    b. Right-click Command prompt and select Run as administrator.

  2. Enter the following command, and press Enter:

    If the service is enabled, then the result should look like the following screenshot:

    If the START_TYPE is not set to AUTO_START, then you'll need to set the service to automatically start.

Use the command line to set the Windows 10 diagnostic data service to automatically start:

  1. Open an elevated command-line prompt on the device:

    a. Click Start, type cmd, and press Enter.

    b. Right-click Command prompt and select Run as administrator.

  2. Enter the following command, and press Enter:

  3. A success message is displayed. Verify the change by entering the following command, and press Enter:

  4. Start the service.

    a. In the command prompt, type the following command and press Enter:

Ensure the device has an Internet connection

The Microsoft Defender for Endpoint sensor requires Microsoft Windows HTTP (WinHTTP) to report sensor data and communicate with the Microsoft Defender for Endpoint service.

WinHTTP is independent of the Internet browsing proxy settings and other user context applications and must be able to detect the proxy servers that are available in your particular environment.

To ensure that sensor has service connectivity, follow the steps described in the Verify client connectivity to Microsoft Defender for Endpoint service URLs topic.

If the verification fails and your environment is using a proxy to connect to the Internet, then follow the steps described in Configure proxy and Internet connectivity settings topic.

Ensure that Microsoft Defender Antivirus is not disabled by a policy

Important

The following only applies to devices that have not yet received the August 2020 (version 4.18.2007.8) update to Microsoft Defender Antivirus.

The update ensures that Microsoft Defender Antivirus cannot be turned off on client devices via system policy.

Problem: The Microsoft Defender for Endpoint service does not start after onboarding.

Symptom: Onboarding successfully completes, but you see error 577 or error 1058 when trying to start the service.

Solution: If your devices are running a third-party antimalware client, the Microsoft Defender for Endpoint agent needs the Early Launch Antimalware (ELAM) driver to be enabled. You must ensure that it's not turned off by a system policy.

  • Depending on the tool that you use to implement policies, you'll need to verify that the following Windows Defender policies are cleared:

    • DisableAntiSpyware
    • DisableAntiVirus

    For example, in Group Policy there should be no entries such as the following values:

    • <Key Path='SOFTWAREPoliciesMicrosoftWindows Defender'><KeyValue Value='0' ValueKind='DWord' Name='DisableAntiSpyware'/></Key>
    • <Key Path='SOFTWAREPoliciesMicrosoftWindows Defender'><KeyValue Value='0' ValueKind='DWord' Name='DisableAntiVirus'/></Key>

Important

The disableAntiSpyware setting is discontinued and will be ignored on all client devices, as of the August 2020 (version 4.18.2007.8) update to Microsoft Defender Antivirus.

  • After clearing the policy, run the onboarding steps again.

  • You can also check the previous registry key values to verify that the policy is disabled, by opening the registry key HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows Defender.

    Note

    All Windows Defender services (wdboot, wdfilter, wdnisdrv, wdnissvc, and windefend) should be in their default state. Changing the startup of these services is unsupported and may force you to reimage your system.

    Example default configurations for WdBoot and WdFilter:

    • <Key Path='SYSTEMCurrentControlSetServicesWdBoot'><KeyValue Value='0' ValueKind='DWord' Name='Start'/></Key>
    • <Key Path='SYSTEMCurrentControlSetServicesWdFilter'><KeyValue Value='0' ValueKind='DWord' Name='Start'/></Key>

Troubleshoot onboarding issues on a server

Note

The following troubleshooting guidance is only applicable for Windows Server 2016 and lower.

E0209 Sentinel Key Not Found Fix Windows 7

If you encounter issues while onboarding a server, go through the following verification steps to address possible issues.

You might also need to check the following:

  • Check that there is a Microsoft Defender for Endpoint Service running in the Processes tab in Task Manager. For example:

  • Check Event Viewer > Applications and Services Logs > Operation Manager to see if there are any errors.

  • In Services, check if the Microsoft Monitoring Agent is running on the server. For example,

  • In Microsoft Monitoring Agent > Azure Log Analytics (OMS), check the Workspaces and verify that the status is running.

  • Check to see that devices are reflected in the Devices list in the portal.

Confirming onboarding of newly built devices

There may be instances when onboarding is deployed on a newly built device but not completed.

The steps below provide guidance for the following scenario:

  • Onboarding package is deployed to newly built devices
  • Sensor does not start because the Out-of-box experience (OOBE) or first user logon has not been completed
  • Device is turned off or restarted before the end user performs a first logon
  • In this scenario, the SENSE service will not start automatically even though onboarding package was deployed

Note

User Logon after OOBE is no longer required for SENSE service to start on the following or more recent Windows versions:Windows 10, version 1809 or Windows Server 2019, or Windows Server 2022 with April 22 2021 update rollup.Windows 10, version 1909 with April 2021 update rollup.Windows 10, version 2004/20H2 with April 28 2021 update rollup.

You may have encountered the error - Windows resource protection found corrupt files but was unable to fix some of them when using the SFC utility. What causes this error? How to solve it? MiniTool will analyze this error and offer you some solutions.

Quick Navigation :

Reasons for the Error

System File Checker (SFC) is a built-in utility in Windows 10 that can help you scan and fix detected corrupted system files on your device. This utility has been applied since Windows 98. For Windows Vista/7/10, this utility is integrated with Windows resource protection.

However, sometimes it goes wrong and doesn’t work. What’s worse, you may encounter some errors like the Windows resource protection found corrupt files but was unable to fix some of them Windows 10 error discussed in this post. Some users said that SFC Scannow command cannot fix the found corrupted system file after July 9 Updates.

It means that the System File Checker finishes the scan process and found some corrupted system files but it is unable to fix some of them. This error happens frequently and upsets many users who are using the SFC utility.

To fix the Windows resource protection found corrupt files but was unable to fix some of them Windows 10 error successfully, you need to find out the causes behind it. According to investigation, there are several factors that can lead to the error.

The false positive is the first one to blame. Many elements will result in a false positive within the SFC utility. One of the frequently encountered false positive is Nvidia’s opendll.dll file. The SFC may mark it as corrupted file even though it is not corrupted in fact.

The bad sectors of your computer hard drive could also be the cause for the sfc /scannow found corrupt files error occurred when running the SFC command.

The interference of third-party software is also responsible for the error - Windows resource protection found corrupt files but was unable to fix some of them. If any installed applications on the computer conflict with the SFC utility, you may also encounter this error. According to user reports, executing the SFC utility in clean boot can avoid the error.

There is irregular system file corruption on your computer. In some cases, the SFC Scannow failed to fix error happens due to certain degree of corruption that cannot be fixed by the SFC and DISM (Deployment Image Servicing and Management) utility. In this case, you need to perform a clean/repair install.

How to fix the issue SFC scannow not working? Here, this article focuses on two cases of SFC error. Try to use the following methods.

Solution 1: Run the DISM Command

DISM (Deployment Image Servicing and Management) is also a Windows built-in program that exists from Windows Vista. It is a utility that can do the work of SFC utility. However, there are some differences between their work principles.

The SFC usually replaces the corrupted files with locally stored copies, while DISM utilizes Windows Update component to finish the work. To keep the DISM running properly, you are required to get a steady Internet connection before executing the command.

Tip: You need to pay attention to that fact that the stored copies in local can get corrupted too.

How to execute the DISM command? Here is the full guide.

Step 1: Type cmd in the search box, and then right click Command Prompt from the search results. Click Run as administrator from the pop-up menu.

Step 2: In the pop-up window, type DISM /Online /Cleanup-Image /RestoreHealth and press the Enter key.

Step 3: Then, the utility will run the command automatically. What you should do is to wait patiently. The whole process may take you less or more than one hour based on your computer configuration.

Tip: You cannot close the window before completing the operation. If the scan gets stuck when getting around 30%, it is a normal phenomenon. So, you don’t have to do any operation and keep waiting the finish of the process.

Step 4: When the process ends and informs you that the file corruption is resolved, reboot your PC and run an SFC scan at the next setup to check if the error is fixed.
