I'm having problems with my WCF site. In this sites, I've been using WCF REST Services, and once in a week (sometimes sooner, sometimes later), the IIS suddenly stops responding. The response for all requests is a 401 error
401 - Unauthorized: Access is denied due to invalid credentials
I'm not using any kind of authentication rule in this site. I tried to active the IIS Request Filter, but the action of activating the filter solves the error. An IISRESET also solves the error. The windows logs doesn't report any kind of error, and the
IIS logs looks under normal activity (I don't think this could be a DOS attack)
I don't know where else to look for. Any help would be really appreciated

Hi, Any news on the issue?

We had the same error here. I tried in desperation to give "Network Service" and IUSR modify access to the webroot and all files and folders under it and the error is now completely gone. It's not a valid solution in the long run, but it seems to have fixed
Could you try the same and see if the error stops for you as well?.
