    Hi everyone,
    I am getting an error that is related to the WebResource.axd, as described in the Event Viewer.. This caused my application pool to stop running because after 5 consecutive errors within 5 minutes, IIS automatically disables the application pool.

    This is what I see in the Event Viewer:

    Event Code: 4005
    Event Message: Forms authentication failed for the request. Reason: The ticket supplied was invalid.
    Event Detail Code: 50201

    Request Information:
    Request URL: https://domain.com:443/AppName/WebResource.axd?d=4rxWZLa16xfVnip0ScOwlSFQgWqV91HZa614kGmY6nu-ls1XMhprh5YkpF3DJTbHlaungWY1ofirz4hip35f3A2&t=63367448160000000
    Request Path: /AppName/WebResource.axd

    Does this make sense --> /AppName/WebResource.axd?
    That file is not physically there, so why is it referencing that?

    This is just the first error. The next one, after 3 seconds, points to a RadWindow page, with the same error: Ticket supplied was invalid.  Then the 3rd one goes to my Login page... Same error, Ticket supplied was invalid.  Then it tries the Login page again: Ticket supplied was invalid.. Then the final error goes back to the WebResource.axd with the same error. Then my IIS server just decides to quit because too many errors happened in a span of 10-20 seconds.

    Any thoughts on this, anyone?

    Hi Mikhail,

    We have a series of blog posts that explain how WebResource.axd works and what are the common issues with it.


    As for the error you receive - try setting the machine key explicitly by following this guide.


    I hope this helps.

    All the best,
