Windows 2003 server and IIS 6

I posted this on the Install newsgroup but got no response, so thought I would try here as many Windows experts read this group. Does anyone have experience of installing either PHP 4.4 or PHP 5 in this environment. I am quite experienced in writing PHP applications running under IIS 5, MS SQL on XP boxes, but now have a project we need to run on one of our 2003/IIS 6 machines. I've downloaded the installer, and selected IIS 6 as the web server but I get an error saying script is incompatible with W Script (or similar) then asking me if I want to make C script the default for running Visual Basic scripts. We don't really want to do this, as we run a lot of other stuff on this server written in VB. As a result, the auto configuration of IIS 6 doesn't happen, I've tried it manually but failed dramatically, I so screwed IIS 6 it won't even serve .htm pages anymore ........ Any help very much received Blu n.b. I do know that once I've got php working in the environment, I have to additonally sort the extensions for gd2 and MS SQL support.
