Coonect RDS server issue

I tried to connect RDS server using ColdFusion Report Builder.

I got HTTP/1.1 404 Not Found.

I contacted Web Server Administrator that they said they created my ID and password.

I would like to know are there any way to check client side issue to connect to RDS server.

I have a ColdFusion developer version on my local machine and I am able to connect local developer version ColdFusion Server.

My local version is ColdFusion 10, remote server is ColdFusion 9.

Your help and information is great appreciated,

Regards,

Iccsi,
