Zenon RT Services won't start on Standby Server

Zenon RT Services won't start on Standby Server

Hi ,
We arranged a simple network topology : 2 Servers(A primary and a secondary/Standby Server) and one client(that will act as an engineering system too).
When we try to connect remotely to servers and start runtime project on them, everything goes fine except that we receive an : "Interactive Services Detection" Notification on Standby server windows. Although Runtime won't appear on Standby server(just an empty desktop and an "Interactive Services Detection" Notification on system) , Everything on network is working fine( even switching between 2 servers) . And as i checked in task manager, none of Zenon related services are not started! I wonder what is causing this weird problem.
Thanks!
