Bad driver high cpu usage correlation ???

    Recently I have had the following two issues, I am relativlely new to SBS
    2003 so please bear with me.

    After booting our HP Server, I receive an error saying one or more drivers
    has failed during start up. ( I don't know how to go about finding which
    driver)

    Also the server CPU usage jumps to 100% while using a specific application
    on client workstations. The process' that take up the CPU usage are:
    lsass.exe
    svchost.exe (11 of them running in task manager)


    While researching the issue online it seems there may be a correlation with
    the bad driver causing the high cpu usage, is this possible??

    Does anyone know how to track down which driver is giving me the boot-up
    error?

    Thanks for any help,
    Chris

    Do you have APC PowerChute Business Edition version 6.x installed? If so,
    boot into Safe Mode and disable the "APC PBE Agent" and "APC PBE Server"
    services, reboot normally, remove version 6.x and install version 7.0.4.

  3. Right. And if that's not the issue, a failing driver should be logging
    itself in the event logs. A great free tool called Process Explorer will
    tell you what specifically is causing high CPU that's showing as svchost or
    any other mystery process
    http://www.sysinternals.com/Utilities/ProcessExplorer.html. It's pretty
    self explanatory - basically you're just expanding a tree of running
    processes until you see the one that's generating the CPU cycles, then look
    underneath that process to see specifics.

    Gregg, thanks for the suggestions, however I don't have APC PowerChute
    Business Edition.

    Dave, I had already attempted to use Process Explorer. However due to my
    lack of knowledge I am unfamiliar with what I am looking for once I have
    isolated the process causing the high CPU usage.

    I will keep on it....

    Thanks,
    Chris
