.net SSIS包连接问题

我面临有关SSIS包连接的问题。我已经创建了SSIS包，每天晚上导入和导出数据。它正在我们的服务器上工作，但我们的一个客户端面临以下问题：

    SSIS Error Code DTS_E_OLEDBERROR.  An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available.  Source: "Microsoft SQL Server Native Client 10.0"  Hresult: 0x80004005  Description: "Login timeout expired".
An OLE DB record is available.  Source: "Microsoft SQL Server Native Client 10.0"  Hresult: 0x80004005  Description: "A network-related or instance-specific error has occurred while establishing a connection to SQL Server.

An OLE DB record is available.  Source: "Microsoft SQL Server Native Client 10.0"  Hresult: 0x80004005  Description: "Named Pipes Provider: Could not open a connection to SQL Server [53]. ".

SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER.  The AcquireConnection method call to the connection manager "XXXXXXX" failed with error code 0xC0202009.  There may be error messages posted before this with more information on why the AcquireConnection method call failed.

component "OLE DB Source" (1) failed validation and returned error code 0xC020801C.

One or more component failed validation.

There were errors during task validation.

我已经使用管理工具验证了该服务器上数据库的连通性，并且运行良好

如果有人面临这种问题，请告诉我

谢谢…

我知道了，SQL数据库的连接有一些问题。感谢所有人的帮助。

在将连接作为命令行参数时，我看到了类似的问题。然后，问题是验证使用了存储在OLE DB组件中的连接字符串，而不是参数中的连接字符串。您在遇到错误时是否验证了连接？发生错误时是否检查了SQL Server日志？可能是发生了备份之类的事情。你需要查看日志，日志，日志
