Where to get a Dos RDP and a Thin Client?

Can any body help finding a dos rdp and a thin client. I have tried that 'Terminal Soft RDP'.

I've moved this post out of Other Tutorials as this isn't a tutorial. I have to honestly admit not spending much time on thin clients but have you tried a quick Google search? I know I found http://www.thethin.net which might be a good place to start. Do you need both to be dos-based?
