I solved my own problem. I had been using to ISAPI filters. One called
multisite.dll and one called iis_multiplex.dll. Since I had no more need for
them, I removed them and now IIS no longer crashes when I refresh the screen.

I had seen somewhere else that bad ISAPI filters are frequent causes of IIS
crashes. Keep this in mind.
