My all applications were working fine but suddenly all sites under IIS are not loading css, images, scripts. It redirect to login page.
If i login it works fine. e.g. mysite.com/Account/LogOn?ReturnUrl=%2fpublic%2fimages%2ficons%2f41.png
On my local machine it works fine without login.
It was windows permission issue i move the folder thats it inherit wrong permissions. When i move to wwwroot folder and add permission to iis user it start working fine.
