We are currently having an issue where new deployments are completing successfully and do show up in the console but with a 'no entry' sign on them.
If we right click the new device there a minimal option available in the context menu.
The agent installed and all the services are running on the Client and the Core.
However I can see that the inventory scan is going straight into the ErrorScan folder.
This is using LDMS 2016.3 with Service Update 3.
Not had this problem before.
