VNC settings for default user account.

Good morning, when I try to connect to the thin client running WES with VNC a window pops up on the User account asking to accept the connection, if I hit yes it it tries to connect for ten seconds or so then says authentication failed. Now if I log on the built in admin account I can vnc in fine, with no query, because I shut it off. But apparently this only affects the admin. I do not want a query window to pop up I just want it to connect and allow me remote control. Any suggestions?
