Crashing IIS?

Hi folks, I had the ... dubious ... pleasure of running some PHP code on an IIS system recently and noticed a peculiar occurrence... I called setCookie(), and something in it caused IIS to crash. Dead. Gone. Shuffled off this mortal coil. Stuffed. Like a parrot. :) As an alternative, I instered manual Header() commands to get the same effect as setCookie(). Same thing. Dead. Stuffed. Etc. Has anyone encountered this kind of muckup...? And if so, what did you do about it? Jason -- Jason Murray jasonm@melbourneit.com.au Web Developer, Melbourne IT "Work now, freak later!"
