Hi All, I am trying to upgrade our existing ArcGIS Standalone server version from 10.8.1 to 11.4. We are using windows authentication to access rest URL's. But getting 500 internal error after installing 10.4 web adaptor. I followed the process of upgrading the server to 10.9.1 and then to 11.4. 10.9.1 web adaptor URL is working fine. Getting error while using 11.4 URL. I tried installing new 11.4 version instead of upgrading but still getting the error "500 internal server error." Rest end URL is working fine for anonymous authentication. Getting problem only while windows auth is enabled.
