I have the options set to restrict a user to a single session in RDS however I am having problems with two things. i initially thought it was because I had a startup script setup in GPO however I removed that and the issue is still happening.
1. If a user disconnects they do not always get reconnected to their disconnected session.
2. A user with an active session can go on a different device and connect and get a new session on a different session host.
Configuration:
3 Session hosts
RDS Session Broker (Is the session broker for 2 different RDS farms)
GPO to restrict users to a single session in place for session hosts
