I have a VMWare Windows 2012 R2 server running SQL 2012 and I keep getting the below error. If I manually create the SPN can I ignore this error? I can make it go away by using a domain administrator account to start the SQL Service but I do not like this option. Attached is the SQL Error log<br />
<br />
The SQL Server Network Interface library could not register the Service Principal Name (SPN) [ MSSQLSvc/Server.domain.org<wbr /> ] for the SQL Server service. Windows return code: 0x21c7, state: 15. Failure to register a SPN might cause integrated authentication to use NTLM instead of Kerberos. This is an informational message. Further action is only required if Kerberos authentication is required by authentication policies and if the SPN has not been manually registered.

When a SQL 2012 was setup in a domain if a SPN creation error is in the SQL error log and the SPN is created manually and the error still occurs in the log is that an issue?
