I think this should be possible if you keep in mind that each session will be displayed on 1 screen (1 left and 1 right). But keep in mind that using the generic Wyse logon box both session will use the same login, if you don’t use this you will be hitting the annoying Windows idle logon timeout.
Please correct me if you got some other thoughts about the setup.
Please post your wnos.ini so i can see if we can help you out with the needed settings.
