    The newsletter module was disabled in our website since the client didn't need it. The line was commented in the <modules> section of the .config.

    Until now, because i'm trying to re-enable it.

    When i'm trying to access the module from the admin section, I get the following error:

    An error occured while instantiating the proxy type.
    Telerik.WebServices.DynamicProxy.ProxyInstantiationException: An error occured while instantiating the proxy type. ---> System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

    I've read in another thread, that I could try to delete the .dll in ~/Sitefinity/ServiceAssemblies. When I do so, and I try to access the module, the .dll does not get re-created and I get this error:

    There was an error downloading 'http://localhost/SiteFinityApp/Sitefinity/Admin/Services/MailingWebService.asmx?WSDL'.
    System.Net.WebException: There was an error downloading 'http://localhost/SiteFinityApp/Sitefinity/Admin/Services/MailingWebService.asmx?WSDL'. ---> System.Net.WebException: The request failed with HTTP status 401: Access Denied.

    But I am able to access the WSDL from my browser...

    Any idea what the problem could be ?

    Thank you,

    Hi Olivier,

    Make sure that the account that runs ASP.NET worker process has access over the SiteFinityApp/Sitefinity/Admin/Services/ folder. You can use a third party tool like Fiddler to narrow down from where the issue might comes from. The error says that the worker process does not have permissions over the Services folder or the dll that is dynamically generated. Note that the dll will be generated only in full trust environment because of the Reflection usage.

    Best wishes,
