Hello,We are seeing a strange issue when we connect to our SQL server using the DNS name vs the hostname or fqdn. When connected via the DNS name and running the statement, [b]select auth_scheme from sys.dm_exec_connections where session_id=@@spid[/b] the auth_schema returns as NTLM. However that same select statement returns kerberos when we use the name of the server. Any ideas? The SPN is registered and delegation has been setup but maybe something else has to be changed when using DNS names?Thanks for any advice.
