Was wondering if anyone can advise.


Onboarding our devices to ATP. We use the onboard file and deploy the file using Microsoft Endpoint Manager. I can see the file is install successfully however the device is not showing in ATP.


Have used this URL to help troubleshoot but to no avail:


I think it maybe a networking/firewall issue. Is there a way for me easily to identify whether the endpoint can reach the ATP URLs, ICMP is blocked. 


What is odd the issue only occurs on a domain machine, on a non domain joined machine it works and registers into ATP.


If anyone can advise it would be greatly appreciated.



@isotonic_uk , I think you are taking about MDATP (endpoint protection), while this forum is for AATP ...

Thanks, yes that's correct. It was MDATP i was referring to.
