最近写Sandboxieplus劫持com请求方法的例子，RpcSs和DcomLaunch都是服务类型，需要详细了解SandboxiePlus如何实现服务隔离的。即本文剖析一个问题：SandboxiePlus如何管理一个服务的。
Windows服务对应的文件有两种类型：
一个Windows服务必须存在存在两个处理逻辑：ServiceMain函数和ServiceCtrlHandler函数。如果该服务是由svchost.exe进行托管的话，这个dll必须导出ServiceMain函数，函数名不可以改变。ServiceMain函数是服务的主要逻辑代码，ServiceCtrlHandler函数主要响应来自SCM(服务控制管理器)各种控制命令，比如：STOP和SHUTDOWN。下面将使用如下代码生成服务ServiceTest.exe文件研究SandboxiePlus如何实现服务的隔离。
执行sc create ServiceTest binPath= "D:\test\service_test_exe.exe" DisplayName= "Service Test" start= auto 命令来创建服务，注册表方面的修改如下：
主要逻辑：首先查看是否是沙盒化服务，如果是调用SbieDll_StartBoxedService，向SbieSvc进程发送MSGID_SERVICE_RUN请求；否则调用SbieDll_CallServer函数，向SbieSvc进程发送MSGID_SERVICE_START请求，启动服务。
SbieDll_StartBoxedService对应的源码如下：
Scm_StartBoxedService2函数对应的源码如下：
调用StartService之后，对应服务的注册表内容如下：
使用DebugView可以看到服务输出的内容，如下图：
启动的服务进程会被再次注入SbieDll，其对StartServiceCtrlDispatcher hook的代码如下：
对RegisterServiceCtrlHandler函数hook的源码主要设置Scm_Handler或Scm_HandlerEx，如下：
该函数可产生暂停、停止和恢复服务等效果，主要逻辑：设置服务的注册表SBIE_ControlCode键实现。上文中的Scm_StartServiceCtrlDispatcherX函数设置了hEvent来监听是否设置了SBIE_ControlCode，如果设置了就调用Scm_Handler或Scm_HandlerEx，通过这种方式实现了模拟SCM发送各种控制码给ServiceCtrlHandler函数的过程。
这些函数主要查询注册表中的信息，一些函数如下：
SubscribeServiceChangeNotifications和NotifyServiceStatusChange，这两个函数都是用于监控服务或SCM的状态改变。具体用法可以见微软的MSDN文档。这里举出两个使用情况：
对于SubscribeServiceChangeNotifications来说，SandboxiePlus对应的hook函数并没有实质的内容，目前是一个空函数，对应的代码如下：
对于NotifyServiceStatusChange来说，SandboxiePlus对应的hook函数主要逻辑：
对应的源码如下：
Scm_Notify_ThreadProc函数的源码如下：
