HTTP Error 404

Hi,,

We are working on a project using the available "web server" demo program in DE2-115 kit manual. we have created our own webpage and tried to fuse in the same way as the one available with demo program. It is getting built properly and able to assign IP address for the kit. but we are getting problem saying 404 "not found" error when we want to access the website in other syatems connected to the same network. Please someone help us in resolving this error.
