2012 RDS DNS Round Robin
In a simple setup, we have two session host servers and a connection broker server. There is a DNS round robin setup that internal users hit the DNS name. The users are given a login screen but upon entering the login details and pressing enter, the user is then forced to a login screen of the other server. I presume that this is because the RR has given a certain server, but the connection broker is then forcing to another one as part of its role. Is there a way of stopping the second login or should it be configured a different way?
Ah, this is usually caused by the client that is connecting not using Network Level Authentication. What are you trying to connect from?
I believe it requires a remote desktop client which has version 6.0+ of RDP implemented. FreeRDP 1.0.1 supports it too I believe.
