I'm running an MVC app on Windows Server 2003 using Integrated Authentication. I have a page that is running into reauthentication problems only when it performs a large number of inserts. After a certain amount of time (~ 1-2 minutes) users are asked to enter their network username, password, and domain. This message appears three times, then an error page is displayed with a 401.1 error. The exact error message in the log is: 401 1 2148074248.
The user is not asked for their network password anywhere else in the application and not consistently on this page?only if processed a large inventory which means a lot of inserts. I have added ?executionTimeout="3000"? in the the web.config file to prevent a previous error of HttpException (0x80004005): Request timed out., however, the user is still being asked to re-authenticate.
Entry in log file:
