We have just deployed a asp.net project onto our testing server which was working fine on our development server. However once it was deployed to our testing server two pages (out of 10+) are generating 401 errors. The permissions on the pages that are returning the error are the same as the pages that are working.
- The server it is running on is Windows Server 2008.
- The web server we are using is IIS7.
- We only allow anonymous authentication.
Update: While the two pages are consistently returning 401's it is now sporadically happening for other pages for short periods of time.
What could the possible reasons for this be?
