c++关机，怎么关LAN中的机器。

[newman0708]

//ShutDown.cpp

#include "stdafx.h"

using namespace std;

int _tmain(int argc, _TCHAR* argv[]){

TOKEN_PRIVILEGES tkp;
HANDLE hToken;

if (!OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
{
//MessageBox("OpenProcessToken failed!");
cout<<"OpenProcessToken failed!";
}

LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME,&tkp.Privileges[0].Luid); //获得本地机唯一的标识
tkp.PrivilegeCount = 1;
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,(PTOKEN_PRIVILEGES) NULL, 0); //调整获得的权限

if (GetLastError() != ERROR_SUCCESS)
{
//MessageBox("AdjustTokenPrivileges enable failed!");
cout<<"AdjustTokenPrivileges enable failed!";

}

BOOL fResult =InitiateSystemShutdown(
NULL, // 要关的计算机用户名,可在局域网网中关掉对方的机器，NULL表示关本机
"由于系统不稳定，WINDOWS将在上面的时间内关机，请做好保存工作!", // 显示的消息
10, // 关机所需的时间
TRUE,
TRUE); //设为TRUE为重起，设为FALSE为关机

if(!fResult)
{
//MessageBox("InitiateSystemShutdown failed.");
cout<<"InitiateSystemShutdown failed.";
}

tkp.Privileges[0].Attributes = 0;
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,(PTOKEN_PRIVILEGES) NULL, 0);

if (GetLastError() != ERROR_SUCCESS)
{
//MessageBox("AdjustTokenPrivileges disable failed.");
cout<<"AdjustTokenPrivileges disable failed.";
}

ExitWindowsEx(EWX_SHUTDOWN,0); //开始关机


return 0;
}


以上程序可以关机，但怎么关LAN中的指定机器？

谢谢！

BOOL fResult =InitiateSystemShutdown(
NULL, //把这个NULL变成你要关掉的计算机的名字,比如"Server" // 要关的计算机用户名,可在局域网网中关掉对方的机器，NULL表示关本机
"由于系统不稳定，WINDOWS将在上面的时间内关机，请做好保存工作!", // 显示的消息
10, // 关机所需的时间
TRUE,
TRUE); //设为TRUE为重起，设为FALSE为关机

LAN中的pc，可怕办不到吧！

lpMachineName
[in] Pointer to the null-terminated string that specifies the network name of the computer to shut down. If lpMachineName is NULL or an empty string, the function shuts down the local computer.

msdn上这么写的，我也不清楚

如果你可以写一个简单的网络程序,LAN中的是你的CLIENT,Server发出一个关机的命令,立刻关闭远程的计算机

[newman0708]

BOOL fResult =InitiateSystemShutdown(
"10.23.4.11", //把这个NULL变成你要关掉的计算机的名字,比如"Server" // 要关的计算机用户名,可在局域网网中关掉对方的机器，NULL表示关本机
"由于系统不稳定，WINDOWS将在上面的时间内关机，请做好保存工作!", // 显示的消息
10, // 关机所需的时间
TRUE,
TRUE); //设为TRUE为重起，设为FALSE为关机


不能成功，出现报错“InitiateSystemShutdown failed.”

要目标机器上作个服务端，接收消息，然后关机

仅仅该个计算机名是不够的，还有改变privilege的。使用SE_REMOTE_SHUTDOWN_NAME查找

Remarks
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. For more information, see Running with Special Privileges.

Common reasons for failure include an invalid or inaccessible computer name or insufficient privilege. The error ERROR_SHUTDOWN_IN_PROGRESS is returned if a shutdown is already in progress on the specified computer.

A non-zero return value does not mean the logoff was or will be successful. The shutdown is an asynchronous process, and it can occur long after the API call has returned, or not at all. Even if the timeout value is zero, the shutdown can still be aborted by applications, services or even the system. The non-zero return value indicates that the validation of the rights and parameters was successful and that the system accepted the shutdown request.

When this function is called, the caller must specify whether or not applications with unsaved changes should be forcibly closed. If the caller chooses not to force these applications closed, and an application with unsaved changes is running on the console session, the shutdown will remain in progress until the user logged into the console session aborts the shutdown, saves changes, closes the application, or forces the application to close. During this period, the shutdown may not be aborted except by the console user, and another shutdown may not be initiated.

Note that calling this function with the value of the bForceAppsClosed parameter set to TRUE avoids this situation. Remember that doing this may result in loss of data.


Windows Server 2003, Windows XP: If the computer is locked and the bForceAppsClosed parameter is FALSE, the last error code is ERROR_MACHINE_LOCKED. If the system is not ready to handle the request, the last error code is ERROR_NOT_READY. The application should wait a short while and retry the call.

shutdown不就行了吗
