Recommended Configuration for IIS?

[Kathy_OC]

I have installed PHP 5.2.5 on IIS 5.0 (Windows 2000 - SP4) using ISAPI. I'm running into two significant problems which I believe are either IIS or PHP bugs:
1) ASP sites produce an error after PHP pages are viewed. This is only resolved temporarily when I restart IIS.
2) Blank data is saved when I try to update MySQL and then redirect to a new PHP page (I'm trying to use a multi-page form). Valid data is saved if I redirect to a HTML page.

So I'm looking for some advice ...
What IIS/PHP configuration works well?
Should I use ISAPI or CGI or FastCGI? Why?
Would IIS 6.0 be an improvement over IIS 5.0?

Also, I already think that Apache would work better than IIS, but my organization is pretty committed to keeping IIS. So if you want to recommend Apache and can refer me to a source with some data that I can try to use to convince my boss to switch, then I would welcome that as well.

Thanks,
Kathy

the only thing I could find that was authoritative in any way was this
