Windows server 2012 R2 RDS users cals

I,m running Windows 2008 DC network with Windows 2008 TS server for Citrix deployment

Now i need to deploy new TS 2012 r2 Application server with 5 users.

I attached new Dell Windows 2012 R2 server to windows 2008 domain, apply all patches and start to add roles for  RD broker, RD web access and RD host licence...but deployment is failed..

I just need local Windows 8x or 10x pro users RDP to Win 2012 R2 server....

What do i do wrong ???

Regards
