SQL 網路介面 (SQL Network Interface) 程式庫無法註冊 SQL Server 服務的服務主要名稱 (SPN)。錯誤: %1。無法註冊 SPN 可能迫使整合式驗證回到 NTLM 而非 Kerberos。此為參考用訊息。只有在驗證原則需要 Kerberos 驗證時，才需要採取其他動作。

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.
