igang med aspx

Jeg har installeret frameworks på serveren. I forvejen er der IIS, MSQL og den nyeste MDac. Så det skulle vidst være iorden.
Nu kopierer jeg så noget koden fra microsofts quickstart og kalder filen intro1.aspx. Denne fil gemmes på serveren. Jeg kalder filen i browseren og får følgende fejlmeddelelse:


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>


Hvad har jeg glemt. Det er forøvrigt lige meget hvad jeg skriver som filnavn. Så snart extension er aspx får jeg den her fejl.
