See this error, Plesk 11 on Win Server 2012, in plesk go to the domain and then Customizing Subscription, then the Permissions Tab, make sure ‘Hosting settings management’ is ticked, save.
Now check the versions of .net on the dom in plesk.
In IIS on the server make sure the IUSR for that dom is set on the dom.
(Also handler mappings may need to ‘Revert to Parent’
One thing I noticed is that trying this wiped the asp and .net settings at some point, so, I;ll keep an eye on that.
Most likely causes:
- The file extension for the requested URL does not have a handler configured to process the request on the Web server.
Things you can try:
- If the file extension does not have a handler associated with it, add a handler mapping for the extension.
- Verify that the handler associated with the file extension is properly installed and configured.
- Create a tracing rule to track failed requests for this HTTP status code. For more information about creating a tracing rule for failed requests, click here.

This error means that the Web server does not recognize the file extension of the requested resource. A module handler is not configured on the Web server for this extension. If the file extension being denied is required by the Web server, add the appropriate handler for the file extension.View more information »
