vb.net - 使用以SYSTEM身份运行的vb.net应用程序，如何为每个登录用户启动分离的进程？

Question

经过数周有关此主题的研究，我终于决定开始我自己的话题，希望有经验的人可以为您提供帮助。我搜寻了互联网，试图了解其中的各种编码示例，但是我试图将一个可行的解决方案整合在一起。让我从一些背景开始-

背景：
我有一个vb.net应用程序，该应用程序将使用CA IT客户端管理器（ITCM）交付给我组织中的Windows服务器和PC。与Microsoft SCCM一样，CA ITCM在每台PC上都具有作为SYSTEM运行的代理服务。因此，当我的应用程序在目标PC上交付并执行时，它正在“ NT Authority \ SYSTEM”上下文中运行。

问题：
在应用程序的初始阶段，在每个需要停止的登录用户的上下文中都有一个正在运行的进程。在我的应用程序执行结束时，我需要为每个登录用户重新启动此过程，以防止他们必须注销并重新启动。我要停止的进程实际上是一个系统托盘进程，用户可以在其桌面上与之交互。

追逐VB.NET解决方案：
不断地在Internet上进行研究，似乎没有针对每个问题的本机.NET解决方案，而没有每个登录用户的密码或提示用户输入一些凭据。由于这不是我的选择，因此我需要找到一种启动过程的方式，而不必知道或要求登录用户的凭据。

经过研究，我找到了Windows API函数CreateProcessAsUser。据我了解，我可以按照以下方式做一些事情（见下文）

笔记：
这是我第一次在VB.NET中使用非托管代码调用Windows API。当我将各种文章中的代码拼凑在一起时，关于常量，枚举和函数声明有很多歧义。如果您发现这些声明中的任何错误，请告诉我。关于何时需要将数据类型“封送”为其他类型，我有很多问题。请仔细阅读！！

由于有来自类似帖子的无数示例，因此我尝试遵循CreateProcessAsUser页面上的MSDN示例：

MSDN链接：

范例连结：

除了查看每个Windows API调用的有效性之外，请查看操作的总体顺序，并让我知道我是否过于复杂或什至可能缺少某些内容。我没有从Microsoft示例中实现的唯一代码是允许每个SID完全访问交互式Windows工作站，然后允许SID完全访问交互式桌面。也许我错了，但我认为每个用户都应该已经可以访问其交互式桌面！

我的结果：
当前，我正在测试从管理员帐户（从本地计算机上的Visual Studio 2010运行我的解决方案）到通过ITCM交付应用程序（从本地计算机上的SYSTEM帐户运行）对LaunchProcess函数的调用。在这两种情况下，我都会在用户会话中启动指定的进程，但是出现以下错误：

“该应用程序无法正确启动（0xc0000142）。单击“确定”关闭该应用程序。”

我希望有人可以检查我的代码并为我指出正确的方向。否则，请告知我如何调试这里的问题。

非常感谢您的提前输入。

解决方案：

在发布完整的代码解决方案之前，我想分享如何找到答案。在重温有关CreateProcessAsUser API函数的MSDN文章之后，我意识到我需要验证我的进程是否真正拥有该文章提到的必需特权：

SE_INCREASE_QUOTA_NAME

SE_ASSIGNPRIMARYTOKEN_NAME

另外，本文未提及，但对于查找和调整令牌特权以启用上述特权的其他一些相关Windows API调用来说，可能至关重要的是：

SE_TCB_NAME

回想一下，我的应用程序是使用CA的IT客户端管理器（ITCM）软件交付的，以Windows Server和PC为目标。核心CA ITCM代理服务以“本地系统”身份登录，但其插件执行所有脏工作，并以SYSTEM帐户运行。显然，SYSTEM帐户和“本地系统”帐户之间存在巨大差异。

使用SysInternal的Process Explorer工具，我能够检查我的应用程序，发现它没有拥有所有必需的特权。自运行测试以来已经有一段时间了，所以我忘记了实际上没有持有哪个特权。

我最初犯的错误是编写非托管的Windows API函数调用以尝试启用丢失的特权，但不幸的是，这种方式不起作用。要么您的进程拥有特权，要么没有特权。如果它拥有特权，那么您唯一的责任就是确保启用特权。

为了克服这个问题，我不得不使用另一种方法。为了获得所需的特权，我的应用程序需要作为服务安装并执行，因此可以作为“本地系统”帐户运行。但是，仅将整个应用程序重新设计为可安装的服务，以满足这一简单要求是没有意义的。

相反，我创建了第二个VB.NET项目，这是我要发布的代码。第二个项目是一个简单的Windows服务，它带有启动参数。第一个启动参数是您要为每个登录用户启动的应用程序。在启动切换到您指定的应用程序时，将传递所有剩余的启动参数：-)

有了现在拥有适当特权并可以动态接收启动参数的服务，该服务可以为每个登录用户确切指定要启动的内容，我将生成的可执行文件嵌入了我的第一个项目。

我的第一个项目以SYSTEM帐户身份运行，它具有安装新系统服务的权利/许可/特权。它还有权启动该系统服务，并为系统中的每个登录用户传递启动启动托盘服务所需的参数。问题解决了！

这是我的Windows服务的代码-

实现方式：

如上所述，我已经从第二个项目中获取了服务可执行文件，并将其作为“现有项”添加到Visual Studio中到我的第一个项目中。然后，我更改了“构建操作”，将服务可执行文件嵌入到我的第一个应用程序可执行文件中。

当第一个应用程序在目标计算机上执行时，它将运行代码以将嵌入式可执行文件提取到目标计算机。您可以使用Google的代码，这非常简单。

将嵌入式服务可执行文件解压缩到本地系统上的路径后，这是我运行的四个“ sc”命令-

sc create <ServiceName> binpath= <Full Path to Service Executable> start= demand
sc start <ServiceName> <Full Path to App to Launch for all Users> <Parameters>
sc stop <ServiceName>
sc delete <ServiceName>

注意：在第一个sc命令中，请记住在等号后放置空格。

使用sc命令比使用installutil.exe或创建安装项目以将服务打包到MSI中并安装它要简单得多。只要确保您等待返回的每个sc命令，然后再继续执行下一个命令即可。

最后说明：

对于所有提供正面见解和反馈的人，非常感谢您的所有帮助。我很乐意为自己这样的好人发布代码。对于所有告诉我无法做到这一点或试图断言闯入用户台式机并运行某些东西的恶意软件的人，我有礼貌地鼓励您开始思考。我不希望你在我的团队中工作！

心态过得很滑，只是因为某些事情可能在不当之手上带来恶意或危险的影响，而根本不应该做到这一点。您发臭的思维与宇宙中所有美丽的事物背道而驰。
