Question

我有一个SSIS包，它使用Microsoft.ACE.OLEDB.12.0提供程序从制表符分隔的文本文件中读取信息。包中有一个脚本任务，其代码如下：

DataTable dtFiles = new DataTable();
string connStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileInfoLocation + ";Extended Properties=\"text;HDR=NO;FMT=TabDelimited\"";

OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM RepairFiscalYears.txt", connStr);
adapter.Fill(dtFiles);

这个包作为本地用户运行，比方说UserA。最近，一位同事在运行SSIS包的同一个盒子上创建了一个Windows服务。服务的“登录身份”设置为与SSIS包运行时相同的UserA。现在当我尝试运行SSIS包时，我在adapter.Fill（dtFiles）行上出现以下错误。

如果我停止服务并运行包，它可以正常工作。如果我重新启动该服务并运行该程序包，它将失败，因此我可以轻松地重现该问题。为什么在与SSIS包相同的用户下运行的Windows服务会导致与OLEDB提供程序的这种冲突？

请记住，Windows服务不会对包执行任何操作，即不会从任何相同的位置/文件/等读取/写入。

非常感谢任何帮助。
