Really interesting post! After trying this on my home network I find that I can shutdown any pc froma ny other pc. The one problem I have with this is as follows:

Maybe I have a pc running improtant tasks and it also has shared folders (so it has NETBOIS shares) and I dont really want my flatmates shutting it down whenever they feel like it: So How do I stop “shutdown -i” from working on my 24/7 pc?

I’ve tried disabling shutdown via gpedit and in the registry, and i’ve blocked remote registry and remote windows admin. via thwe windows firewall. No luck. When ever they feel like it, my flatmates can shutdown my pc’s using “shutdown -i” and they don’t even need to supply a password!!

As usual you’ve done a top job of explaining how to bypass your own feeble security. How about explaining exactly how I PREVENT all the tools in my class from shutting down the lab pc’s when I’m the only one trying to learn something!

Windows 7 Pro appears to be immune to such “ordinary” tricks as gpedit to prevent shutdown, disabling remote access/remote admin in the firewall and so on. After ensuring that my sys. admin had disabled all of these options, it seems that a simple “shutdown -i” is all that is needed to remotely shutdown the pc’s of students that actually want to do some work.

Bravo Microfuckwits, your joke OS is as insecure and open to expolitation as ever!

now i am thinking of writing a program in c++ which will shutdown an range of ips on a network… so all i’ll have to do is just find the subnet range and shit all over’em
haha

for the people who are such dummies: ever heard of search engine google.com?
and if u have the genuine enthusiasm, u’ll find info an anything
not everything can be spoonfed to you

It has great features and has reasonble pricing.

rem @echo off
echo > C:\restarted_servers.log
shutdown -r -f -t 00 -m \\pc
if %errorlevel% GEQ 1 goto ONE
if %errorlevel% LEQ 0 goto ZERO
goto END

:ZERO
echo Restarting mgtfin02 was successful at %date% %time% >> C:\restarted_servers.log
goto END
:ONE
echo Restarting mgtfin02 failed at %date% %time% >> C:\restarted_servers.log
:END

Whether the pc is restarted or not the errorlevel value is always 0. What else can i use to check if the restart was successfull apart form the errolevel?

Thanks

I open up run
type in cmd
in their i type in shutdown -I
then I click add computer
then i type in //(insert ip adress here)
and shut it down

I am writing a batch script that will be restarting 25 network machines on the network. After a successful restart the event should be logged on to a log file same as if the restart was not successfull. Am having problems using errolevel since it is alway returning 0 whether restart is successful or not. Please explain to me how you can use if sateents to check whether the shutdown command actually restartd the pc or not

I’ve had some problems with the *.bat-file

It isn’t working problerly. Can you tell me how I run cmd?
NB: I’m using Windows 7

You can shutdown a remote computer over the Internet, but you will have to connect to the target computer through VPN of some sort. Private (LAN) IPs are not routable over public network (Internet). Secondly, you can block ports 137, 138, 139, and 1900 from and to the Internet to prevent such intrusion. Unbinding the File and Printer Sharing service from the NIC that’s connected to modem also helps to secure your computer.
