I have been onboarding Servers to Windows ATP by installing the Microsoft Management Agent, and pointing the agent at the Azure Workspace for ATP. This has worked for 19 of my 25 servers.
The remaining servers are showing a connection to the Azure workspace as successful, but are not appearing in ATP. I have gone through a number of steps based on the few articles I can find, but I can't see the issue with these servers.
I was wondering if anyone has had similar experiences and may be able to point me in the right direction?
