Hi flyerstarter,

I was having the same problem as you were, it turned out for me to be the isapi settings.  I would suggest a few things..

1)  Make sure all .net related mappings for your particular site (not just the root site) are pointing to the proper framework isapi dll.  Even though my root web site was pointing to 2.0, my actual dnn site was using the 1.1 framework for some reason  My thread is below

2)  If that doesn't help, I would download Fiddler at the URL below (its a MS product), run it while you request your page and then look through the log and see if you notice anything wrong (anything in red would be a problem)  From there you can hopefulyl try to see what the root problem is)

If you're running Windows 2003, each site you setup can be configured to use a different framework version and each .NET 2.0 Framework version can be setup to allow .axd or not. 

Excluding the "compression" software you were using, I'd go and compare the mappings again on each site.

Or, how about setting up a whole new web site in the IIS console, installing DNN 4.3.3 on that, and allow .axd and see if a new web site works.

Another possible troubleshooting step is to see if trace.axd works after you enable it in the web.config for the dnn site.  Add the following xml after the <system.web> node:

    <!--  APPLICATION-LEVEL TRACE LOGGING
          Application-level tracing enables trace log output for every page within an application.
          Set trace enabled="true" to enable application trace logging.  If pageOutput="true", the
          trace information will be displayed at the bottom of each page.  Otherwise, you can view the
          application trace log by browsing the "trace.axd" page from your web application
          root.
    -->
    <trace enabled="true" requestLimit="10" pageOutput="true" traceMode="SortByTime" localOnly="false" />

If pageOutput="false", you will need to access trace.axd by adding it the url, e.g. http://localhost/dnn/trace.axd

Assuming .axd is enabled for that site, you should see the trace output at the bottom of the page.

If that works, I'd guess that there is some other issue besides enabling .axd for the site.

Hi All,

I would request core team to help me on this. I created a DNN site and it works fine until I enable windows authentication. Once it is enabled, I am not able to user UPDATE buttons as it give javascript error. I ran fiddler and it shows me error 500 for webresource.axd. The stack trace is -

NullReferenceException: Object reference not set to an instance of an object.]
   DotNetNuke.Security.Authentication.Configuration.GetConfig() +16
   DotNetNuke.HttpModules.AuthenticationModule.OnAuthenticateRequest(Object s, EventArgs e) +25
   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +92
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +64

It seems like window authetication is stopping webresource.axd to down to temporary files. I don't know how to solve this and would appreciate your help ASAP.

Cheers,

Sanjay
