Hi,

Thanks.

Re: reboot machine

Hello Avi,

Use WMI for this, it's natural way

Sub RebootComputer( strServer )
Set objOSSet = GetObject("winm gmts:{(RemoteSh utdown)}//" & strServer
& "/root/cimv2").ExecQue ry("select * from Win32_Operating System where Primary=true")

For each objOS in objOSSet
objOS.Reboot()
Next
End Sub

Re: reboot machine

Hello Avi,

Did you try to look in MSDN for the info how to use WMI (Management namespace)
and try to convert my script to C#?
It takes less than 5 mins for this (sample in MSDN is available, you need
only point correct query and method)

//Connect to the remote computer
System.Manageme nt.ManagementSc ope ms = new ManagementScope ("\\\\<your_ser ver_name>\\root \\cimv2");
ms.Connect();
//Query remote computer across the connection
System.Manageme nt.ObjectQuery oq = new System.Manageme nt.ObjectQuery( "SELECT
* FROM Win32_Operating System");

ManagementObjec tSearcher query1 = new ManagementObjec tSearcher(ms,
oq);
ManagementObjec tCollection queryCollection 1 = query1.Get();

foreach (ManagementObje ct mo in queryCollection 1)
{
string[] ss ={ "" };
mo.InvokeMethod ("Reboot", ss);
Console.WriteLi ne(mo.ToString( ));
}

Unfortunately, there's no "one-liner" that you could call in C# to reboot
the machine. Instead, it is a little bit more complex due to special
privileges you will need. The Win32 API function to reboot the machine is
ExitWindowsEx. See this page for details:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shutdown/base/exitwindowsex.asp

Now, to the C# code. There is the direct P/Invoke route, and the WMI route
that Michael Nemtsev pointer out. Try this page for tips:

Good luck!

Re: reboot machine

Hello Jani Järvinen [MVP],

There is the sample of using ExitWindowsEx from C#

Reminds me of the good old days, when you could write REBOOT.COM (using DOS
DEBUG) in a couple of asm statements...

Add to that a simple Process.Start call that issues the shutdown.exe
program.
