The Use RD Connection Broker load balancing machine setting should be configured correctly. This policy setting allows you to specify whether to use the RD Connection Broker load balancing feature to balance the load between servers in an RD Session Host server farm. If you enable this policy setting, RD Connection Broker redirects users who do not have an existing session to the RD Session Host server in the farm with the fewest sessions. Redirection behavior for users with existing sessions is not affected. If the server is configured to use RD Connection Broker, users who have an existing session are redirected to the RD Session Host server where their session exists. If you disable this policy setting, users who do not have an existing session log on to the first RD Session Host server to which they connect. If you do not configure this policy setting, you can configure the RD Session Host server to participate in RD Connection Broker load balancing by using the Remote Desktop Session Host Configuration tool or the Terminal Services WMI provider.
