DBNETLIB][ConnectionOpen (Connect()).]SQL Server 不存在或访问被拒绝

Question

将包移至另一台服务器后，我无法使用存储过程xp_cmdshell或作业来运行它。该包存在于文件系统中，我已将其添加到 SSIS 包存储中。如果我在 BIDS 中运行它，它就会运行。如果我从包存储中运行它，它就可以正常工作。当我尝试从作业或存储过程运行它时，我收到以下错误：

SQL Server 服务和 SQL Server Agent 服务均使用本地系统帐户登录。我已将创建者名称和创建者计算机更改为已移动到的生产服务器。

这是我的包中的连接字符串：

Data Source=MyServer;Initial Catalog=MyDB;Provider=SQLOLEDB.1;Integrated Security=SSPI;Auto Translate=False;

提前感谢您提供的任何帮助。
