I am trying to run a remote application outside the network via wireless internet connection; the mde file is stored locally on the terminal server. The problem is I get the following error when I try to connect.. Your Remote Desktop commotion failed because the remote computer cannot be trusted…………..The CA Root certification is not trusted; install this certificate in the trusted root certification authority’s store. Is there a way to bypass this

The Certificate issued to the RDS server is likely locally issued (local CA), you need to add the remote CA certificate as trusted.

By pass the warning or bypass the need to add the certificate as suggested while being able to connect?

Do you have control over the server?  You could change the mode.
Note that the certificate provides for the encryption of the connection which might otherwise be unencyrpted.

Why not add the Internal CA as trusted and be done with it?

Are the tablets joined into the domain?
Publishing the CA root in the AD as trusted via a GPO is the simplest way.

When the tablets are being setup, the first thing to do is to add the CA.

On the server side, check the settings for terminal service and change it to the older version.
GPO to control terminal server functionality:

ref security and require secure RPC might be what you are looking for.
