Load balancing terminal servers w/o Session Directory

Changing the timeout option may help a little bit, but the basic issue is still not solved. With Session Directory disabled, msrdp persistence will persist to the same server during the same session. Once you disconnect (but *don't log out*), the next time you log in, you are a new user. There is no token to connect you with a session that is running on a particular terminal server. Your experience proves validates this behavior. If you enable Session Persistence it will work. So if you want it to reconnect to an already establish connection, you have to enable Session Persistence, or find a way to replicate the functionality of session directory. It's not that the session times out too early, it's that you have no way of knowing the existence of an existing session. Increasing the timeout will actually aggrevate the problem more. In fact, if the timeout is too long, ALL available servers could theoretically be "tied up" and no user could connect to either terminal servers. If anything, lower the timeout.
