Problem with Connection Broker name

Hi,

When i change the connection broker name using for example:

And setup a DNS pointing to NewBrokerName.domain.com

When someone tries to connect it gives him the following error:

"Your computer cannot connect to the remote computer because the Connection Broker couldn't validate the settings specified in your RDP file. Contact your network administrator for assistance".

What am i doing wrong?

Sincerely,
AM
