    Pupils can shutdown a machine from IE shortcut

    Hi

    I have just found out the students have been circulating a shortcut via email that shuts down the computer. in the target it has C:\Windows\System32\shutdown.exe -r and start in is C:\Windows\system32

    Any ideas on how I can stop this from running? Cmd prompt is disable d by GPO so not sure where else to prevent this from running.

    Thanks

    Sorry not of much help on this one. Although why don't you want them to shut down computers, big wool they've shut down their own machine and now have to turn it back on and log back in, I don't understand how they could be using this maliciously or am I missing a point here?

    Time wasted in lessons? If they send out in an email possibly named as something like unfiltered internet, students then open it. Losing work if they haven't saved! I know you say "big wool" but its trying to prevent time and work being wasted in the first place!.

    what email are you using? can you prevent .url and .lnk extensions from being sent around?

    And .zip files

    We do, all the usual risky extensions are blocked plus .lnk, .url, .zip and .swf too. We've not found a single legitimate email with a zip attached to it!

    I disabled shutdown for students in a GPO. This means they have to log off before shutdown which teachers like as they don't have to wait for stations to be booted up in between lessons.

    You can probably prevent this with software restriction policies in the temp folder, I do this anyway with exe etc. lnk and url should work too.

    Personally i wouldn't disable shutdown via a GPO, students might start just flicking switches on the wall or holding power buttons in at the end of the day.

    Plus a decent email system scans zip files
