Sikkerhedsproblemer med asp.net og "web.config"

Hej folkens,


Først fik jeg følgende:

Server Error in '/' Application.
--------------------------------------------------------------------------------

Security Exception
Description: The application attempted to perform an operation not allowed by the security policy.  To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Requested registry access is not allowed.

Source Error:


[No relevant source lines]

Stack Trace:

  System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +154

Herefter indsatte jeg følgende i "web.config":

<location allowOverride="true">
<system.web>
  <securityPolicy>
      <trustLevel name="Full" policyFile="internal" />
      <trustLevel name="High" policyFile="web_hightrust.config" />
      <trustLevel name="Medium" policyFile="web_mediumtrust.config" />
      <trustLevel name="Low" policyFile="web_lowtrust.config" />
      <trustLevel name="Minimal" policyFile="web_minimaltrust.config"/>
  </securityPolicy>
  <trust
      level="Full"
      originUrl=""
      processRequestInApplicationTrust="true"
  />
</system.web>
</location>


Så får jeg følgende:

Server Error in '/' Application.
--------------------------------------------------------------------------------

Hvad kan jeg gøre?
