High Kernal Usage - What might this be..?

    our Win2000 File Server seems to slow down considerably during certain
    periods of the day!

    (we've not manage to assess weather it is over the exact same time each day)

    I've noticed that in task manager, during these periods the Kernel CPU Usage
    seems to jump from around 9% - 55%
    I'm sure it's usually a lot low then this..!
    and the SYSTEM Process jumps around 2-11% CPU Time

    nothing else in the processes list seems to be using any major CPU Time

    the server has no network application running. in fact there are no third
    party apps running on it.
    and is configured for optimal File Share performance

    the main purpose of the server is to server MS Access database files around
    5-70MB in size

    for most of the day it does this fine, but during these periods the database
    come to a grinding holt.

    does anyone have an idea where to start looking..?

    what sort of background services use lots of Kernel Time..??

    I thought it might be a scheduled Defrag, but that doesn't seem to have been
    the problem..!

    any help would be greatly appreciated be me...and my users.

    Perhaps it is resizing your page file due to increased
    usage at that time, have you checked the pages/sec
    counter? Or there could be a virus. maybe it is
    renewing its DHCP lease, or checking for and installing
    updates from windows update.
