Dear,
I have configured the HA connection Broker on 2012 R2 withe SQL 2014 Std Edition.
When I have one server connection broker is down (server A) on the second connection broker server (server B) in Remote Desktop Server Manager I have this error :
All services are started on second server B .
For your information I have create database on the server A and I have only one database on server A . On the second server I have SQl is installed and I configured right in SQL server , add firewall rules , configured SQL management TCP/IP.
In this deployment the connection broker server is worked correctly I can connect on the RDHS servers.
Thanks for your support.
