• Thanks HanShi.

    This is the error from the error log:

    2018-02-26 22:35:15.77 Server  The SQL Server Network Interface library could not register the Service Principal Name (SPN) [ MSSQLSvc/MY-PC:50925 ] for the SQL Server service. Windows return code: 0xffffffff, state: 63. 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.

    What is best work around? Uninstall reinstall SQL? or is there an easier fix?
