Hi
I have set up a SQL Server 2019 server. When it is set up to use LocalSystem I can connect from my desktop and I have KERBEROS authentication.
If I change it to use a domain account I get the following error

I checked the SPN for the account and saw the below

I then removed these and when I started SQL Server it had recreated them again.
In the SQL Server Logs I see the following

Can anyone tell me where I have gone wrong? The only difference between this and our other servers are that this is Windows and SQL 2019 and most of our estate is 2016.
Thanks
Sam
