The SQL Network Interface library could not register the Service Principal Name (SPN) for the SQL Server service

I got the following message logged into Error log [Server Machine running SQL Server 2012] and both standalone POS running on the Back office server freezes up. Is there a solution to this problem? Any help would be appreciated.

The SQL Network Interface library could not register the Service Principal Name (SPN) for the SQL Server service. Error: 0x54b, state: 3. Failure to register an SPN may cause integrated authentication to fall back to NTLM instead of Kerberos. This is an informational message. Further action is only required if Kerberos authentication is required by authentication policies.

Thanks,

Pappu
