Server Error in web.config

Hi,

My web.config contains the following settings
 

 <customErrors mode="RemoteOnly" defaultRedirect="~/Errors/Default.htm">
      <error statusCode="404" redirect="~/Errors/Http404.htm"/>
    </customErrors>


Now i deployed my site in the server and the url is going to be used by Remote machine

but i am getting the following error.

============================================================================

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>
 
======================================================================================

but if i run this url on server machine it is working fine,

So, Please suggest me what are the changes should I need to do more.
