Hi,

Every time when I open the browser at home page, showing '500-internal server error' and the page address was redirected to '.../dnn/DesktopModules/AuthenticationServices/ActiveDirectory/WindowsSignin.aspx which is not my home page is, should be '.../dnn/home.aspx', then I have to manually change to home link address and the page showed without issues.  

look like the first time open the home page and dnn try to check your login status?

Anyone? Thx!
