Trying to figure out what I’m doing wrong.

I have (3) 2012 R2 RDS Session Host servers
RDSHOST01 – 10.10.10.5
RDSHOST02 – 10.10.10.6
RDSHOST03 – 10.10.10.7

…all 3 server part of a Server Farm (I think it’s called a Collection on 2012+) 
with a single RDS Connection Broker responsible for splitting up traffic 
between the RDS Session Host servers.  No RDS Gateway is involved (I do not 
require external connections to RDS).

I have a (3) DNS A records for the following for Round Robin:
Host: RDSFARM with IP 10.10.10.5
Host: RDSFARM with IP 10.10.10.6
Host: RDSFARM with IP 10.10.10.7

When I RDP into RDSFARM,  I get prompted for credentials.   I enter my domain 
user credentials and receive the usual pop-up message that says, “The identity 
of the remote computer cannot be verified.  Do you want to connect to it 
anyway?”  And it shows my server name on the certificate.  I click YES and I 
get logged in.

Now, logging into to RDSFARM again, the Session Broker will try to send me to a 
different server, so in that case, I get the “The identity of the remote 
computer cannot be verified.  Do you want to connect to it anyway?” prompt 
TWICE.  The first time it shows one server name, the SECOND time, it will show 
a different server room.   So I know it’s the Session Broker redirection 
causing the double prompt.

The question is, why am I prompted twice?   Do I have to use/setup certificates 
on my 2012 RDS environment?  I am NOT using RD Web, or RD Gateway, so I figured 
I would be okay, but… I’m unsure.
