Dragging this morning. hal.dll went blooey on my home PC/server. Mucked about for hours, then reinstalled XP Pro. By 1:00am I had it back reasonably alive, verified the server functionality, still have a few more hours of reloading software.
On the plus side, I really wasn't happy with how the firewall software had been acting recently, so this gave me a chance to review the current state of the market. Picked up a few apps to try later.
