SQL 网络接口库无法为 SQL Server 服务注册服务主体名称(SPN)。错误: %1。注册 SPN 失败会导致集成身份验证仍使用 NTLM，而不是 Kerberos。这只是一条信息性消息。仅当身份验证策略要求使用 Kerberos 身份验证时才需要执行进一步的操作。

The SQL Network Interface library could not register the Service Principal Name (SPN) for the SQL Server service. Error: %1. 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.
