Where did you get nxnode from ?? I guess from nomachines's site.

It's not part of FreeNX, so I recommend you uninstall it.

On your server you need (from Centos)
and preferably also nxclient (from nomachine)

The libraries and binaries are in :-

OK. You said previously that the linux server DIDN'T have X installed.

If you can get a remote X session on the server it is easier to
test X issues.

Does the server have gnome or kde installed.

Try getting a FreeNX gnome session and see if you can get a terminal
running, then at the command line try 


( You do have rdesktop installed on the Centos machine, don't you?? )

That likely means either 
        you aren't running from an X workstation
        X11forwarding is disabled in the server sshd_config
If you can get a FreeNX gnome or KDE running a terminal
        ( it will do fine from your windows client )
        you can forget about ssh -X xterm . . .
