We have an issue in our production environment where accessing the web service (ReportExecution2005) fails with with an 401 unauthorized error. If I access the http://<machine-name>/reportserver or http://<machine-name>/reports from a browser which is started under the same account as the one used to make the above explained web service request, I am able to view the reportserver/reports pages.
On enabling the report server verbose and http logs, we see the below message in the report server log file
http!rshost !d6c!<date-time>:: v VERBOSE: Authentication failed with error state:14
I was not able to find any detailed information about this error state.
Since SQL Server 2008 r2 uses httpsys operating system component for authentication, we enabled error logging for httpsys but surprising there were no log statements logging in the error file when we get this error. Does this mean the error occurs before httpsys component is called?
Any inputs on this issue would be appreciated. Thank you.
