I've just installed RealVNC enterprise edition 4.2.5 on a Win 2003 server. When trying to connect from another windows box, I have no problem, but when I try to connect from a linux box (also running v4.2.5 enterprise edition), vncviewer gives the following and fails to connect:

The RealVNC package was installed from the RPM distribution following the instructions in the RealVNC documentation.
As a matter of interest, running vnclicense produces and aborted message as well when trying to use -add to add the license key.
