Loadmaster in front of two Remote Desktop machines


I'm testing Load Balancer pointed to two windows desktops with Remote Desktop enabled. There's no session broker, etc.. but I'm noticing when a user gets disconnected, they don't always get put back on the same machine they were connected to before. So their session stays "disconnected" and they effectively lose their work. Any settings that would put them back on the same machine they were booted from? Thanks!
