I have installed the necessary GNOME Desktop packages. Installing GNOME Desktop on CentOS 6 on a console before installing xrdp.
But the solution is quite simple. You need to install the tigervnc-server package and just the tigervnc only.
# yum install tigervnc-server
Restart the xrdp again.
# service xrdp restart
