Multiple login prompts using Windows 2008 R2 SP1 RDS Broker

Hello,

I have just setup a new RDS Broker Farm with the following configuration:

2 x Windows 2008 R2 SP1 Session Hosts

1 x Windows 2008 R2 SP1 Session Broker / License Server

Using DNS round robin for the load balancing.

My problem is that when users log in they are prompted with the login screen with the option to login as themselves or other user. When they select their icon they need to enter their password a second time which is very frustrating. It seems like this is a known issue, but I can't find a fix for my environment.

Any help would be much appreciated.

Thanks,

Carsen
