WinCE 4.2 and Remote Desktop Connection

Hi,

We have several thin clients with windows ce 4.2 pro, however none of them have a Remote Desktop Connection.
I'm having trouble to find anything alike and if I try to install a mobile or regular RDC I get the message "This is not a valid Windows CE application".

Can anyone help me on how I can get RDC installed on my Win CE?

Thanks!
