RDP loadbalancing

Hello,

 

Currently , I have created a virtual server with APM. After Authentication, i get to the webtop and launch RDP via RDP Tunnel. User gets to choose which terminal server it needs to connect.

 

Now, I want to do it differently.

 

Now, i want some specific users to authenticate and should get one of the terminal servers ( user cannot choose) as per loadbalancing algorithm defined in the pool so that all the terminal servers are equally used.

 

When i try to use a pool in application tunnel, i dont get to choose pool if i chose RDP.

 

Also, i have tried using Pool Assign and Advanced Resource Assign in APM but i just get "Page Cannot be displayed" after authentication.

 

In the logs, i can see that the it is reaching Advanced Resource and the request is allowed.

 

Please advise.
