sql server 2005一直是在域中,服务器删除域控后,客户端用sa连接提示 sa连接失败。
失败日志 错误: 18456,严重性: 14,状态: 16。
日志在提示sa 登录失败前有这样一段提示:
SQL Server is now ready for client connections. This is an informational message; no user action is required.
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.
请问是什么问题引发sa 登录错误
