问题
We have a aspnet web application that works fine locally. No issues at all.
When published to IIS 7.5 the site loads up, lets me login in and works perfectly. I can login using my own and any other account that is registered.
Problem is - when I close the browser down and then reopen and login again it does nothing.
No error message from IIS, no 'invalid attempt' from the login controls. Nothing.
If I attempt to login with a made up username and password I get the error I expect from the login controls - 'Invalid user name and/or password'.
If I restart or simply change any settings for web site in IIS it works again once -then fails on the next attempt.
I have set 'Rapid-fail protection' to false. I have checked the logs. But I am no nearer to understanding what the problem is.
Can anybody point me in the right direction as I am losing the will to live ! :)
Thanks in advance
