A correct running Windows server should not have 1 or 2 Errors on the dashboard
On a normal working Windows 2016 server I pretty much always have 1 or 2 errors on the Server manager dashboard. Those 2 errors pretty much always relate to 2 services that have no use on a server as they relate to user stuff like syncronising mail and maps.
Could you either simply by default disable those 2 services on a server or make the server manager smarter by not reporting those 2 services not running as an error. By the way, the Sync_Host... service seems to appear and disappear at random.
