For the first time I am deploying an asp.net web-application.

In VS.net on the local IIS everything works fine. But when I do a Project => Copy Project ("File share" and "only files needed to run this application") and I put these files on the web-server by ftp I get the follwing message :

----------------------------------------------------
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".

<!-- Web.Config Configuration File -->

<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>


Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File -->

<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>

------------------------------------------------------

To get more infromation about the error I did what it tells :
I changed this parameter in the config.web file ...

<customErrors mode="off"/>

But it doesn't change, I still have the same error.

Could you help me to figure out what is going wrong ?

Thank you a lot !
