I designed a dotnet website ran very well on my system but when I host will be giving error below.

Server Error in Application.

Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a customErrors tag within a "web.config" configuration file located in the root directory of the current web application. This customErrors tag should then have its "mode" attribute set to "Off".

Any help?
