Windows Defender Security Center
Hi Rshanouda, to your question, no, the trial is not limited in any way in terms of number of machines you onboard.
Likely candidates for this behavior are typically limiting network proxies (easy to test, if possible, put the machine on a direct internet connection and see if it appears).
You can also use the troubleshooting information here - https://docs.microsoft.com/en-us/windows/security/threat-protection/windows-defender-atp/troubleshoot-onboarding-windows-defender-advanced-threat-protection
And here's some good tooling and advice on how to check for connectivity issues from Alex -https://www.verboon.info/2019/02/check-windows-defender-atp-client-status-with-powershell/
If the above doesn't help, I suggest opening a support case (top right corner of the portal under the '?" icon)
- RshanoudaMay 01, 2019Copper ContributorRaviv Tamir Thank you for the help. what about windows 10 Pro is it supported by the console (widows Defender security center) to management all the machine ? and show up all the machines list in on board ? if we buy license for it. or should we need to change 1200 machines in Windows Enterprise ?
Thank you
