We are using SP2013 on-premise. We need to switch a web application Windows Authentication from NTLM to Negotiate (Kerberos):
May I know what is the DNS requirement to support Kerberos?
In my test environment, the Kerberos is working at the beginning. Later when we switch the DNS server due to network issue, all the site collection under that web application is not working. I cannot even create a new site collection. I guess some setting is missed in new DNS server.
