A Symantec Endpoint Protection Manager (SEPM) reports that a Client Health State is "Off-Line" in status even though when inspecting the record in the client management section shows that "Last Time Status Changed" is within the defined intervals and definitions are current.
On the Symantec Endpoint Protection Client (SEPC), the tray icon indicates a green dot. Within the client, when you select "Help" menu > then to "Troubleshooting" > with "Management" selected > On the right where General Information is displayed: Server is connected; the Group is connected and reflecting the correct policy group; and Last Connected shows a time within the predefined intervals.
When you manually update the content on the manager and/or on the client (by selecting update policy). Status does not change.
When you issue commands: such as update, restart, scans, etc., the commands complete successfully.
