    Screnario:
    User is logging onto the domain on his laptop. just after the desktop has
    loaded it reboots - no BSOD, auto restart disabled.
    On restart, laptop proceeds through Check Disk.
    Logon as Administrator - no problems. Access the log files - no entries.
    MSConfig reduced the startup to absolute basic, logged on as user - restart
    after desktop loads and the chkdsk once again.
    Copy made of users documents on the laptop. User profile then deleted from
    the laptop and recreated at next logon.
    Initial logon perfect, no problems. Second logon, back to reboot after
    desktop loaded.

    Any assistance would be most appreciated.

  2. I've never seen anything like this before, but here's where I'd start.

    I can't imagine how this could be related to the SBS or domain. The first
    thing I'd do is to verify that by logging into the laptop while disconnected
    from the LAN. Don't do anything differently from what you're doing now when
    it restarts, except do it while disconnected (including wireless). The
    laptop will log in using cached credentials, and if it restarts, you'll know
    the problem is local to the laptop.

    Go into MSCONFIG and, in addition to setting all of the startup apps not to
    start, disable all of the 3rd party (non-Microsoft) services. If it doesn't
    reboot, start enabling services until you determine which is the culprit.
    Does the problem happen in Safe Mode? If not, that probably indicates
    either a startup app or service, or a driver.

    Manually run Microsoft Update to make sure the laptop is fully patched.

    Check the manufacturer's support web site to see if anyone else is reporting
    this. Check for BIOS and driver updates. If they have a hard drive or RAM
    testing tool, download and run that. (I suspect that if RAM were involved,
    the restarts would happen more randomly). You could try running a chkdsk /r
    on the drive to see what it reports, but if there's a drive diag tool, I'd
    run that too.

    Thanks Dave for the Relpy.

    I tried disableing non MS services with out success, and Safe mode is
    stable. I'm starting to turn toward hardware. The day after posting, the
    laptop booted and loggedonto the domain no problems for 3/4 of the day. After
    4pm however the restarts began.
    Although hardware fault does appear to contradict the fact that the admin
    can logon.
    Thanks again for your reply, it is one that i had not come accross either.
    Cheers,
    Dave.

  4. If the system is stable in safe mode, that would indicate that the problem
    is being caused by something that's disabled in safe mode. I'd look at any
    drivers, particularly if something specific seems to trigger the restart.
    For example, a faulty print driver could crash something only when you
    print, or only when you open Printers and Faxes. There's a long list of
    drivers that don't load in safe mode (I wish I could point you to a list).

    You could take a look at this, which seems like not much more work than just
    replacing the whole PC ; -) Seriously, it might be easier just to check
    for hardware with old drivers by comparing your existing versions with the
    current ones on the manufacturer's web site. You probably don't need to
    look at anything like chipset drivers or anything like that - BIOS, printer,
    video, and NIC are the ones I'd start with.
