Windows 2000 is a slow booting OS period. It took about as long to boot on my PIII 800 as it does on my P4 2.26. All seemingly for no reason with random delays while the bar progresses across the bootup logo.

XP on the 2.26 is up and ready about 30 seconds after I press the power button. That includes my network script and a few other startup processes. That is one nice thing about XP, the optimized boot.
