X-windows Problem /GUI Installation fails

Guys,
I am trying to install few products on my solaris 10 box.
One of these installation would go as GUI installation.

Whenever i run the setup, it throws an error message saying that GUI could not be started.

What all things i need to check on server side as well as client (my windows workstation) side? I am using Xmanager for connecting to the server host.

The only thing i did was : $ export DISPLAY=<my machine IP>:0.0

Kindly let me know what has to be done(any ports to be opened ,any services to be started) ?

Regards
Abhi
