I actually got two total machine lockups yesterday, and they happened to another in my squad (X20) at exactly the same time yesterday.
The second one resulted in me having to restore my registry from a previous backup.
I had taken to killing every extraneous service, process, and system tray haunter before I connect a couple of months ago.(running Win2K). This has fixed CTDs, but the lockups I had yesterday were a new experience.
palef.
