Here is a solution to this error:
Your computer can't connect to the remote computer because your computer or device did not pass the Network Access Protection requirements set by your network administrator. Contact your network administrator for assistance.
This occurs on an HP EliteDesk 800 G2 computer trying to access a MS Windows 2012 Server running Remote Desktop Services (RDS).
On the client computer, if you stop the service called "Intel(R) Dynamic Application Loader Host Interface Service" (jhi_service.exe), you will be able to connect without the error.
That's not a fix - that's a quick band-aid.
To fix this problem, on the client, update the Intel Management Engine Components. HP has them on their support web site.
The files are physically located in:
C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL
I've seen this issue occur with Intel's Management Engine Components version 10.0.28.1000 (9/3/2014). I have seen the error fixed by loading version 188.8.131.521 (dated 9/14/2016).
I have seen other solutions on the Internet, but those address other client configurations.
