    Give this a try.
    Ttype the following commands in the Run dialog box:
    sfc /purgecache
    After the above command runs type the following in the Run dialog box.
    sfc /scannow
    You will need your OS CD. SFC SCANNOW takes about fifteen minutes to run.
    Reboot and test.
    I'm assuming that you ran your scans in Safe Mode.

    Problem has now been resolve. After trying the suggestion from David, the problem still existed.

    We found that all icons in System Tools had been removed together with all icons in Administrive Tools. Once we had restored the icons and opened Scheduled Tasks we found 96 separate entries set to run at 15 minute intervals which ran the said process. Deleting the 96 entries resolved the issue.

    Whatever caused the issue is still a mystery.

    Regards Paul.
