To connect to a MS terminal service requires a piece of client software (eg MSTSC for windows) that 'speaks' RD properly.
According to a quick google, rdesktop claims to do this but I've not tested it myself.

Yes. rdesktop can do this. You can download from Sunfreeware - Freeware Open Source Software for Sun Microsystem's Solaris
