Connecting to Remote Desktop Session Host servers by the Broker

Windows Server 2019


If you followed the article: Setting up an RDS farm under Windows 2012R2/2016, the client connection configuration is done using a Round Robin on the DNS.

What happens if the server returned by the DNS is offline?

The connection will not succeed and an error message is displayed.

Solution: Establish a connection through the Broker service

To solve the round robin DNS connection problem, the connection must be established directly on the broker.

If the Remote Desktop Connect client is configured with the broker’s address, it will not work, the client will try to log on directly to the

broker server itself.
