HI ,
We are getting 401.2 unauthorized error due to invalid credentials when ever Domain controller is patched and rebooted. To resolve the issue we are doing IIS reset.
IIS application using anonymous authentication with domain account identity
We have 10 DC 's in our environment and IIS application application should pick up other available DC when primary DC is unavailable
