I am having trouble onboarding devices into Defender for Endpoint and looking for some input on the ConfigMgr deployment error (0x80070057 The parameter is incorrect) I am getting with my W10 devices.
We are setting up an evaluation of Microsoft Defender for Endpoint (Defender ATP) within our M365 tenant. We run Configuration Manager 2006 on-premise and is configured for Co-Management. I have enabled the Defender for Endpoint trial licenses in our 365 tenant and now trying to onboard devices from Configuration Manager. I followed the documentation Microsoft provided on onboarding devices from MEM Configuration Manager current branch. As of now, the only device I was able to onboard successfully was one Windows Server 2012 R2 device we are using for the evaluation. I can see this device in the https://security.microsoft.com console. The rest of the devices are running Windows 10 and have not successfully onboarded. Most of these devices are returning a "The parameter is incorrect." error when viewing the deployment status from the Monitoring pane of the ConfigMgr console. I have followed through Microsoft's documentation on troubleshooting onboarding but did not find any help from that. Required services are running on the deivces and internet connectivity to Defender URLs tested successful.
I reviewed the C:\Windows\ccm\logs\ATPHandler.log on one of the devices failing with "The parameter is incorrect." and see these errors:
There are a couple of other devices returning a different error, possibly getting further in the deployment, but most are experiencing this "The parameter is incorrect" error.
These are the documents I have gone through...
Microsoft Defender for Endpoint: https://docs.microsoft.com/en-us/mem/configmgr/protect/deploy-use/defender-advanced-threat-protection
Onboard the Windows 10 devices using Configuration Manager: https://docs.microsoft.com/en-us/microsoft-365/security/defender-endpoint/configure-endpoints-sccm?view=o365-worldwide
Troubleshoot Microsoft Defender for Endpoint onboarding issues: https://docs.microsoft.com/en-us/microsoft-365/security/defender-endpoint/troubleshoot-onboarding?view=o365-worldwide
Downloaded this tool and ran on one device that has deployment error. Tests were successful: https://docs.microsoft.com/en-us/microsoft-365/security/defender-endpoint/configure-proxy-internet?view=o365-worldwide#verify-client-connectivity-to-microsoft-defender-for-endpoint-service-urls
Any input is appreciated.
