I have a website, which is intended for logon windows user only, so I set IIS anonymous access = false, windows authenication = true.
and assign all users to a group that have access to the wwwroot website folder.
It works for a long time, suddenly today, no users can access website.
I did some tests find that:
1. all static files works fine, require a windows logon, and if you have a logon, you can access it.
2. all asp.net file, like .aspx or access through controller/view are denied
3. one particular user can login, only if I specify domain-name in front of it (previously, no doman name required), other users still can't even I have domain name specified.
4. that user are owner of the website folder, have full permission, however, if I assign full permission to another user, the other user still can't logon, so I don't know what makes first user can logon.
Please help
