Probleem met interne site op server

[Helogat]

hoi, ik heb op mijn server 03 een intranet site gemaakt.

dit werkt heel goed, maar nu heb ik een wiki geïnstalleerd, en een vwd website gemaakt.

als ik de wiki of de vwd website wil bezoeken krijg ik:

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>

Doe gewoon precies wat er in de error staat:

* inloggen op de server zelf en dan kijken zodat je de fout ziet
-of-
* aanzetten dat je de errors vanaf andere machines kan bekijken

Dan weet je wat er fout gaat

Ik zie:
Server Error in '/' Application.

Weet je misschien wat ik nu moet doen?
