This policy setting allows you to specify the RD Connection Broker server that the RD Session Host server uses to track and redirect user sessions for a load-balanced RD Session Host server farm. The specified server must be running the Remote Desktop Connection Broker service. All RD Session Host servers in a load-balanced farm should use the same RD Connection Broker server. If you enable this policy setting you must specify the RD Connection Broker server by using its fully qualified domain name (FQDN). In Windows Server 2012 R2 for a high availability setup with multiple RD Connection Broker servers you must provide a semi-colon separated list of the FQDNs of all the RD Connection Broker servers. If you disable or do not configure this policy setting the policy setting is not specified at the Group Policy level. Notes: 1. For Windows Server 2008 this policy setting is supported on at least Windows Server 2008 Standard. 2. This policy setting is not effective unless the Join RD Connection Broker policy setting is enabled. 3. To be an active member of an RD Session Host server farm the computer account for each RD Session Host server in the farm must be a member of one of the following local groups on the RD Connection Broker server: Session Directory Computers Session Broker Computers or RDS Endpoint Servers.
