    pcs shutting down Whats causing it ?????

    yestoday i had 2 calls saying that they had pcs restarting them selves.
    In one of the ict suites 4 or 5 pcs logged the user off without saving work and then restarted. No messages about updates were displayed.
    The 5 pcs that did restart are all in a line. They were'nt randon pcs in that room.

    This happened in our success maker suite as well. 10 pcs did the same thing. Each one went down in turn going round the room.

    Today the successmaker suite has done it again.

    I've checked sophos for viruses. I dont think its win updates from wsus.

    Any ideas guys. At the moment we've had to close the suite

    Check the local GPO permissions for what access level is required to do a remote shutdown/reboot. At my old place they hadn't got this set right and one little %^&* found out and would randomly reboot/shutdown computers. (You can set it so no message is displayed) Also, if its a script (one after the other sounds that way) it could still be the same command.

    And now for darker view... check your servers/tech machines for schedueled scripts... Have you had anyone leave recently?

    Oh yes, have you checked the event logs on those machines? Not sure if anything will be there, but worth a look

    Did they really log the user off first, or just restart?

    The symptoms match the smoothing capacitor issue that we were plagued with a few years back.

    Depending on the time interval between shutdowns, you may want to monitor what the users are doing and see if one of them has managed to gain access to Computer Management somehow (context menu of an icon on desktop?)

    If in CM, you can switch to another computer and bring up the property sheet, go to Advanced, then Startup and Recovery, and there is a shutdown button with various options in there including restart. Does exactly what it says on the tin...

    Otherwise, as Midget says, blaming Successmaker is easier!

    Re: pcs shutting down Whats causing it????????????????????????

    We had a few calls about a particular room, saying PC's kept turning themselves off etc etc. to which we responded at the time "Yeah yeah, whatever, it'll be the kids turning each others pc's off"...

    Turned out they're gx270's with dodgy caps and they were shutting themselves off! Oh well...

    You might like to check for remote control software like LanView or NetSupport (if you use them). It could be the kids have found a teachers login details and are logging in and doing this.

    I would try and capture the screen dump [ if using XP / 2000 ] The stop code [ if any ] my also be in the event viewer.
    Go into the Startup & Recovery and see if Automatically restart is enabled. If so, un-check it and wait for BSOD !!

    What keyboards are you using cos we found in one of our suites that the keyboards had three grey keys and one of them shutdown the computer we have since disabled this function. Simple things first.

    Could be worth checking the event viewer to see if anything strange caused the reboot. Other then that over heating or faulty RAM may be the issue.

    Re: pcs shutting down Whats causing it????????????????????

    i noticed in one pc that the event log was corrupt.

    I checked 2 others. they both had an entry to do ACPI
    AMLI: ACPI BIOS is attempting to read from an illegal IO port address (0x71), which lies in the 0x70 - 0x71 protected address range. This could lead to system instability. Please contact your system vendor for technical assistance.

    the other entry is
    Windows saved user BISHOPS\ils registry while an application or service was still using the registry during log off. The memory used by the user's registry has not been freed. The registry will be unloaded when it is no longer in use.

    This is often caused by services running as a user account, try configuring the services to run in either the LocalService or NetworkService account.

    not sure what either of these mean.

    I went to see the taecher from the ict suite that had shutdowns. Turns out the kids do get a message. Windows is shutting down, please save your worketc"

    I've not seen it, but sounds like the message you get when using shutdown.exe

    Re: pcs shutting down Whats causing it????????????????????????

    We had a similar problem on our CC3 network. Machines were logging users off and they were losing unsaved work. I had a look at the event logs and founs it was the Netop helper service initiating the log off. This service is used by an old version of RM Tutor and other remote control software. RM aid that due to a security hole students were able to run Tutor a as teacher and control other machines. As we don't use Tutor we un installed it everywhere and removed the package from the server. Found out after we removed Tutor that a switch had crashed and was sending loads of garbled tcp/ip packets which may have caused the problem(long shot I know!). Either way swithc was replaced and not had any problems since.

    Last time I saw this it was just after implementing WSUS. If you get the settings wrong it will reboot whenever... Just a thought.
