Hi…
Server on Windows Server 2012 R2. Clients on Windows 10 LTSC 2019.
Clients connect to the server via “Discover new client via IP/hostname hint” no Internet.
The initial archiving is under way. For a few minutes, all is OK and Clients go to the offline state after a few minutes.
Only connecting the client again and restart server helps. But clients go to the offline state after a few minutes again.
