Devices stuck in Passive Mode
Hello. We recently have switched over to Defender for Endpoint as our primary anti-virus. We were exploring ASR rules when we realized that a large number of our endpoints were not being put into a...
Your issue relates to Windows Defender running in passive mode and integration with Defender for Endpoint and Intune. While I can't offer a specific solution, I can give you some suggestions that will hopefully help you resolve the issue:
1. **Verify Intune and Defender for Endpoint integration:** Make sure Defender for Endpoint has successfully connected to Intune. check for any synchronization issues or errors. Ensure that the antivirus policy in Intune has been successfully pushed to all devices.
2. **Check Antivirus Policy Settings:** In Intune, ensure that the antivirus policy is configured correctly. It may be necessary to check for conflicting policies or settings that may cause a device to remain in passive mode.
3. **Using PowerShell for detailed checking:** In addition to `Get-MpComputerStatus`, you can use other PowerShell commands to check the antivirus status of the device in detail. For example, commands such as `Get-MpPreference` and `Get-MpThreatCatalog` may provide additional information.
4. **Viewing the event log:** Check the event log of the device, especially the events related to Windows Defender, for more diagnostic information. Search for relevant error or warning messages in the event log.
5. **Update Windows Defender definition files:** Ensure that Windows Defender's virus and malware definition files are up to date. Sometimes, outdated definition files may cause the device to enter passive mode.
6. **Contact Microsoft Support:** If none of the above steps resolves the issue, it may be necessary to contact Microsoft Support with more detailed device information for specialized assistance.
Regarding VM backups, while backups are an important data protection measure, they may not be directly related to the specific issue of Windows Defender passive mode. Backups are often used to guard against data loss, where your main concern is to ensure that Defender is functioning properly. However, regular backups are still a good security practice that can help restore your system in an emergency.
Finally, make sure you back up your system or create a system restore point before attempting any changes, just in case something unexpected happens.
