How can I quickly shut down all the computers on my network?

Use the FOR command combined with the SHUTDOWN command:

FOR /L %i in (1,1,254) DO shutdown \\192.168.0.%i

Windows XP will let you log-off all users in one line:

FOR /L %i in (1,1,254) DO shutdown \\192.168.0.%i /l

Change 192.168.0 to match you own Network ID.

For Windows Server 2003 based computers you'll need to refine the SHUTDOWN command and provide the reason for the restart or shutdown. For example, if you plan to reboot servers because of a security fix deployment you can use the following command:

FOR /L %i in (1,1,254) DO shutdown /r /m \\192.168.0.%i /d p:2:18

Use SHUTDOWN /? for a complete list of available switches.

Note: The above scripts will cause ALL the computers on your LAN (basically, on the segment you pointed, 192.168.0.0 for the above example) without notifying their users. It will also shut down all your file servers, print servers, domain controllers, e-mail servers and all other Windows based computers. You do NOT want to do that, do you? Change the IP address range to suit YOUR needs!

You can disable other user's ability to remotely shutdown computers by editing their respective Local Security Policy in the User Rights section, or, if you're in a W2K domain you can edit the servers' GPO.

Download Shutdown.exe it you don't have it from http://www.petri.co.il/software/shutdown.zip (11kb). This is a GUI version of the command:

Windows XP has the SHUTDOWN  command built-in, and running it as SHUTDOWN -i will bring up this console:

Many other tools will enable you to remotely shutdown a system.

Use this code:

using System.Management;

public class Win32OperatingSystem
{
public static void Shutdown(string machineName, string username, string password)
{
ManagementScope Scope = null;
ConnectionOptions ConnOptions = null;
ObjectQuery ObjQuery = null;
ManagementObjectSearcher ObjSearcher = null;
try
{
ConnOptions = new ConnectionOptions();
ConnOptions.Impersonation = ImpersonationLevel.Impersonate;
ConnOptions.EnablePrivileges = true;
//local machine
if (machineName.ToUpper() == Environment.MachineName.ToUpper() )
Scope = new ManagementScope(@"\ROOT\CIMV2", ConnOptions);

else
{
//remote machine
ConnOptions.Username = username;
ConnOptions.Password = password;
Scope = new ManagementScope(@"\\" + machineName + @"\ROOT\CIMV2", ConnOptions);
}
Scope.Connect();
ObjQuery = new ObjectQuery("SELECT * FROM Win32_OperatingSystem");
ObjSearcher = new ManagementObjectSearcher(Scope, ObjQuery );
foreach( ManagementObject operatingSystem in ObjSearcher.Get())
{
MessageBox.Show("Caption = " + operatingSystem.GetPropertyValue("Caption"));
MessageBox.Show("Version = " + operatingSystem.GetPropertyValue("Version"));
ManagementBaseObject outParams = operatingSystem.InvokeMethod ("Shutdown",null,null);

}
}
catch (Exception ex)
{
throw ex;
}
}
}

//Note:
Call the function like:
[STAThread]
static void Main(string[] args)
{
Win32OperatingSystem.Shutdown(@"Machinename", @"UserName", @"Pwd");
}

After I run this code, It returned an error back... "RPC Server is unavaible"

It returned the error on " Scope.Connect(); "

Is there anybody solved this error ?

After executing the command it gives an error 'Access Denied'. We want the programme which will not ask any type of user name / password of remote computer. On the basis of computer name / IP address it should work. Is there any thing like that ?
Julius replied to Binny ch on 10-Dec-10 05:43 AM

I tried  ur program code as below and am getting 14 errors:

================
1.The type or namespace name 'ManagementScope' could not be found are  u missing a directive or assembly reference?
2. as 1. above for 'ConnectionOptions', 'ObjectQuery', 'ManagementObjectSearcher','

ConnectionOptions'(), and where ever else these are used.

I have tried adding a few namespaces but none seem to work what am I doing wrong or is this run on a different platform? am using  vista and team studio 2008.
