You are not redirected to the previously-disconnected terminal server session through the TS Session Broker service in a Windows Server 2008-based farm in TS Session Broker

Consider the following scenario:

• You build a Windows Server 2008-based farm in Terminal Services Session Broker (TS Session Broker). In this farm, some terminal servers that are running Windows Server 2008 are joined.
• You clear the following options on the terminal servers that are running Windows Server 2008:
  • Use IP address redirection (recommended)
  • Participate in Session Broker Load-Balancing
• You use a user account to create a terminal server session through the TS Session Broker service to these terminal servers. This user account receives a "start a program on connection" policy that starts a program when a connection is created.
• You create a terminal server session to a terminal server by using this user account, and then you disconnect the session.
• You create a terminal server session to another terminal server by using the same user account.

In this scenario, you are not redirected to the previously-disconnected terminal server session. Instead, a new terminal server session is created.

This issue occurs because the TS Session Broker service does not detect a disconnected terminal server session on another terminal server for this user. Therefore, the Session Broker cookie cannot be sent. This behavior causes a new terminal server session to be created. However, the expected behavior is that the user is redirected to the previously-disconnected terminal server session.
