Question

Using VBscript to reboot remote machines

Asked by: midwest_rocker

I am trying to come up with a VBscript that will allow for remote execution of a reboot or shutdown to a group of specified computers within my Domain. The purpose is to 'refresh' any changes on the network. (by no means am I a wizard at VBscript - thats where you guys come in!)

Here is my logic:
- Select target group of computers to be rebooted/shutdown.
- Open up CMD to execute shutdown sequence.
- run reboot command

I get the error ' Variable undefined - GetmachineName'
I don't understand since I have another (huge) script that will run that string with no problem.

Option Explicit
Dim objShell
 
If instr(GetMachineName(), "room#") Then
	Set objShell = CreateObject("WScript.Shell")
	objShell.Run "shutdown /r /t 000"
WScript.Quit
end if

You can't execute the shutdown command from remote except you start shutdown.exe with paremeter /i....but this is only a gui interface...no command line!

The following script should be useful for you


strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate,(Shutdown)}!\\" & _
strComputer & "\root\cimv2")
 
Set colOperatingSystems = objWMIService.ExecQuery _
("Select * from Win32_OperatingSystem")
 
For Each objOperatingSystem in colOperatingSystems
objOperatingSystem.Reboot()
Next

does it have to be vbscript ?

You could use

shutdown -m\\PC01 -r -f -t:5
shutdown -m\\PC02 -r -f -t:5
shutdown -m\\PC03 -r -f -t:5

This forces a shutdown (-s), forcing any apps to close (-f), in 5 seconds (-t:5)

For full sytanx see http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/shutdown.mspx?mfr=true

KCTS -

I would like to use VBscript, simply because I can target a specific room/group of computers in one shot without the use of batch files or having to re-type computer names.


Merowinger -

That script did in fact work - although my goal is to ultimately target a group of computers rather than just one. (you probably knew that) So could i get away with simply inserting the string: (?)

If instr(GetMachineName(), "room#") Then

I am thinking the final script would look something like below. The problem with this is I get the error:
"type Mismatch: GetMachineName" Line:6 Char:1

If instr(GetMachineName(), "RM214") Then
	strComputer = "."
	Set objWMIService = GetObject("winmgmts:" _
	& "{impersonationLevel=impersonate,(Shutdown)}!\\" & _
	strComputer & "\root\cimv2")
 
	Set colOperatingSystems = objWMIService.ExecQuery _
	("Select * from Win32_OperatingSystem")
 
	For Each objOperatingSystem in colOperatingSystems
	objOperatingSystem.Reboot()
Next
End if

what is GetMachineName()?
This is a array?!? Could you please also post how you fill this array?

 

by: midwest_rockerPosted on 2008-04-02 at 07:45:23ID: 21263572

Sure - see snippet below....

I specifically use it to target rooms that have computer prefixed with respective room number. Below is an example of mapping networked printers and network drives.

If instr(GetMachineName(), "RMxxxx") Then 
	objPrinter.AddWindowsPrinterConnection "\\computername\printername"
	objPrinter.AddWindowsPrinterConnection "\\computername\printername"
	MapNetwork.MapNetworkDrive "T:", "\\PathToNetworkDrive"
End If

that does not show how you give GetMachineName some values!!
Please explain what the GetMachineName object is

 

by: midwest_rockerPosted on 2008-04-02 at 08:16:40ID: 21263923

GetMachineName is a string that will simply return the name of the computer that is queried. To my knowledge, I dont believe there are any parameters.

Sorry if I this doesnt help much, but this is why i am here!

 

by: merowingerPosted on 2008-04-02 at 08:20:36ID: 21263969

i don't know that sorry!
But to get the machine name of a computer running the script you can also use this:

dim objNet
set objNet = CreateObject("Wscript.Network")
strComputer = objNet.ComputerName
Msgbox strComputer

It works like a charm - although the first time i ran it, it rebooted MY computer. But you don't advance unless you fall back a bit.
