We have a VMware ESXi VM which is installed by Remote Utilities - Host 7.0.2, normally our users will RDP to it, I start viewer mode on Viewer while user RDP and operate on the VM, the viewer just shows Windows login screen, only when I login from VMware remote console, the Viewer can see the operation.
Please note that Remote Utilities works in a console session and displays exactly what is shown on a remote display which is the reason why you see the Windows logon screen when connecting to a remote machine. Please try using the Terminal user switch icon on the Full Control mode's Toolbar to switch to a specific session and see if this helps.
Could you please clarify if you're connecting to a Server OS or a Client OS and if the terminal session you select is active? Please note that when you want to switch between terminal sessions using the Toolbar menu, the sessions must be active, i.e. running. You cannot create terminal sessions with Remote Utilities, only switch to existing ones. In addition, please note that in case if your Host is running on a Client OS, such as Windows 7 or Windows 10, unfortunately, it won't be possible to connect to an existing session this way.
In case if your Host is installed on a Server OS and the terminal session that you want to connect to is active, then please double-check if the RDP client is configured properly, as such issues might be caused by the RDP client on a server machine being configured for Client OS.
Could you please also let me know if you try logging in (i.e. within your Full Control window), when switching to the needed terminal session and getting the Windows login screen - does this action logs out the other user who was previously connected to the remote Host machine in an RDP session?
One more question, I enable video screen recorder and it recorded the session but the session is not user RDP session. It just records all Windows logon screen while I RDP to target server and watched a movie.
