RD Session broker issue; Cannot connect to one of the host servers through RDC

Question

Hello,
I am testing a RD session broker role.
So I have 4 VMs: lest call them VM1, VM2 VM3 and VM4
VM1 is the DC and all other 3 VMs are under VM1.
VM2 is the Session broker server.
VM3 and VM4 are the host servers which are in a farm called Farm1.
Now I have done everything pretty much right. VM2, VM3 and VM4 all are listed in the Session broker computer local group (which is on VM2 since it is the session broker server)
Then I also have VM3 and VM4 setup in regards to their Remote desktop session host configuration.
RD Connection broker is VM2 and Farm name is Farm1.
everything sounds good right?
Okay.. So then I also have added those "New host (A or AAAA)" for VM3 and VM4 in the DNS on VM1 (which is DC).
Both VM3 and VM4 are set to 100 in "Relative weight of this server in the farm".
Now I am trying to do MSTSC from VM2 to farm1.domain.net. First user goes to VM3 just fine. But when I try to do MSTSC again with the second user, it tells me this:
The remote computer hat you are trying to connect is redirecting you to the remote computer.
Remote Desktop Connection cannot verify that the two remote computers belong to the same farm.
This can occur if there is another computer on your network with the same name as the computer your are trying to connect to.
I have read 10 pages of google search about this and still have no clue what to do. I have tried flushing DNS cache on VM1. Time and date is exactly the same on all 4 VMs. 
I also read the following thread but could not understand the answer that he has given there.

Please help me on this.
Thanks,

Okay, so I found the issue and was able to solve the problem.
Here is how to do this and I wonder why most of the online guides to do this whole thing don't talk about it!
Go to Start --> Administrative tools --> Remote desktop services --> RemoteApp Manager
Now a new window will open and in the window there's a box which says "Overview".
The first option will say " RD Session Host Server Setting; Clients will be redirected to: computer.domain.com"
That's where you need to make a change. If you'd open that, it will tell you that "If the RD session Host Server is in a farm, enter the DNS name of the farm".
So now make that "Server name" look like this: farm.domain.com or whatever your farm's DNS name is.
Do this on all the host servers and yeah then you might need to refresh the DNS settings on the DC. 
It should start working then :)
