My colleague create a new server TEWBIWEBVM04 and I want to add it to my new ARR Server TWBIAP02 with dns alias name APLANNING.
But if I open http://aplanning . It will poput a login window and after 3 times retry.
It show a http 401 unauthorized error .
And If I open http://TWBIWEBVM04 is worked!
And I try to remove TWBIWEBVM01 from webfarm and add my fresh server C01010099.
The http://aplanning worked!
I need your help tell I what;s wrong with TWBIWEBVM04

It sounds like kerberos authenication failed after joining ARR server. Please post your ARR and windows authentication configuration on all IIS servers.

I got 403 error from your image. Could you replace the share link so that I can help you check your configuration.

Thank for your kindly support.
I'd found the root cause .
My colleague had active TWBIWEBVM04 IIS Server's "DIGIEST authentication" !
After uninstall IIS to factory Default. And reinstall IIS.
And add TWBIWEBVM04 to webfarm.
It continue normally !!
