I look after a company with a Windows Server 2012 Essentials server and Windows 10 Workstations.
All of a sudden, all but one of the workstations and the server is unavailable via the remote desktop connection.
On the dashboard of the Server, they are also listed as Offline (Except one workstation and server) under devices.
They seem to be working OK otherwise. They can access files on the server and are using re-directed folders that I believe are working fine too.
I am going on-Site on Wednesday and wondering if anybody has any ideas what the issue may be or where to start looking?
Thanks in advance.
