c - 在 Winapi 中以编程方式关闭远程机器

Question

假设我拥有所有必要的权限，我将如何关闭或重新启动同一 LAN 中的系统。

请看下面的代码

OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES, 
                     &tokenHandle);

    LookupPrivilegeValue("Computer name", SE_REMOTE_SHUTDOWN_NAME, 
                         &tokenPrivileges.Privileges[0].Luid);

    tokenPrivileges.PrivilegeCount = 1;
    tokenPrivileges.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

    AdjustTokenPrivileges(tokenHandle, FALSE, &tokenPrivileges, 0, 
                         0, 0);

    switch(action)
    {
    default:
    case constEWXReboot:
    case constEWXRestartApps:
        if (!InitiateSystemShutdownEx("Computer name","Remote machine shutdown", 10, TRUE, TRUE, SHTDN_REASON_MAJOR_APPLICATION))
        {
            ErrGen(constErrCannotRestartSystem);
        }
        break;

我收到错误代码 #53 未找到网络路径。请建议我哪里出错了。

InitiateSystemShutdownEx win API 函数将执行此操作。

Initiates a shutdown and optional restart of the specified computer, and optionally records the reason for the shutdown.

To shut down the local computer, the calling thread must have the SE_SHUTDOWN_NAME privilege. To shut down a remote computer, the calling thread must have the SE_REMOTE_SHUTDOWN_NAME privilege on the remote computer. By default, users can enable the SE_SHUTDOWN_NAME privilege on the computer they are logged onto, and administrators can enable the SE_REMOTE_SHUTDOWN_NAME privilege on remote computers.
