After hours of trying and re-trying and fustration, I finally installed PHP to work with MYSQL and IIS 6.0 Manager on a Windows XP machine. These are the steps I took. Hope that they work for you...
I installed PHP and MySQL on Windows XP platform with IIS 6.0. Please note if you are running IIS 5.0 Manager that comes with the Windows CD, the first thing I did was search google for "Download Microsoft IIS 6.0 Manager" and go to Microsoft to download and Install it. Once installed IIS 5.1 and IIS 6.0 manager will coexist in "Control Panel -> Administrative Tools".
(I haven't used IIS7 so I cannot comment on it yet)
