Server 2012 RDS Thin Client Problem

Hi ;

I have HP T410 thin clients. I have also Windows Server 2012 Standart Edition. I installed RDS (Session Host and License Server). Lots of users using rds on my network but The T410 users can not using rds. I searched problem and I saw the problem maybe about RDP-Secure layer. I change it to Negotiate from local policy. Still my thin clients dont connect to my server.

Please help me..
