几个月前，我编写了一个VB.net控制台应用程序，用于将一组约100台以上的打印机和1800多位使用它们的用户从一些旧的HP打印设备迁移到混合打印服务器和直接到IP打印解决方案。应用程序使用数据库比较已安装的打印机并删除旧的/无效的共享并重新映射到基于Win2K3的新打印服务器，或创建TCPIP打印机端口并安装驱动程序以直接进行IP打印。VB.net 1.1使用CreateProcessWithLogon API创建TCPIP打印机端口
它工作得很好，但用户需要高级用户权限才能创建TCPIP打印机端口。对于主校园来说，这不是问题，但较小的远程站点需要一个解决方案，允许应用程序由没有权限用户权限的用户运行。
我的解决方案是采用“CreatePrinterIPPort”函数并将其放入它自己的包装应用程序中，然后根据需要使用硬编码的本地管理员帐户从主应用程序调用此目的，但我遇到问题生成createport应用程序时。如果我独立运行应用程序，它将创建没有问题的端口，但是当我在测试应用程序中运行它以使用CreateProcessWithLogon API产生createport时，端口创建失败，并显示“拒绝访问”错误。我仅限于使用.net 1.1，因为2.0完全不在我们的环境中，我被告知它不会被推到这个应用程序。
有什么想法？
