原因：oracle安装目录文件夹的authenticated users用户权限不足，导致asp文件创建数据库连接时，系统无法访问oracle目录

解决方案：以oracle9.2为例

1、在web服务器的oracle安装目录下，右键选择ora92文件夹的属性

2、在“安全”页下将authenticated   user的“读取及运行”的允许取消选中（时间比较长），点击确定

3、再次打开属性页面，将“安全”页下将authenticated   user的“读取及运行”的允许选中，点击确定，即可

如果没有“安全”页，将菜单“工具”->查看下的“使用简单文件共享（推荐）”取消选中，确定即可。
