从 IIS 但不是从 IIS express 调用时，C

本文介绍了从 IIS 但不是从 IIS express 调用时，C_GetSlotList 失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

所以我有这个 c# web 服务，它最终通过放置在 system32 文件夹中的一些智能卡 USB 驱动程序从德国 Elster 工具包 (Eric) 调用 C_GetSlotList() 方法.我在计算机服务器中有一张智能卡.当我在 IIS Express 中托管我的服务时，一切正常，但在 IIS 中却不行.可能是什么问题呢?有什么东西会阻止 IIS 访问驱动程序吗?我确保我使用的应用程序池的身份具有管理员权限.我正在使用 Windows 7 专业版，这是我得到的日志类型:

So I have this c# webservice that eventuallly calls C_GetSlotList() method from the German Elster toolkit (Eric) thru some smartcard usb driver placed in system32 folder. I have a smartcard in the computer server. When I host my service in IIS Express everything works fine, however in IIS it doesn't. What could be the problem? Does something block IIS from accessing the driver? I made sure that the identity of the application pool I'm using has admin rights. I'm using Windows 7 professional and this is the kind of log I am getting:

推荐答案

将 IIS 应用程序池标识更改为 LocalService 通常会有所帮助.不要问我为什么:)

Changing IIS application pool identity to LocalService usually helps. Don't ask me why :)
