samba - Dec 2022 - File server joined to a samba domain accessed by windows 10-11 clients, works via ip no via dns name

By the way: Just checked accessing on of the shares via IP. It's the 
same like your case: The share opens.

Never checked that...

I take it that all the obvious culprits have been checked:

DNS; Can you ping the synology device by name ?
      Can you ping from the Synology device

Time: is the time correct ?

This all sounds like a dns problem or a kerberos problem caused by dns.

When you try to connect using the name, kerberos will be used, but it 
falls back to NTLM if the ipaddress is used. You need dns for kerberos 
to work.
