Thanks for both helpful replies. I'll try to install it on the local Windows 2003 server for comparison. I'd like to install Apache, MySQL and PHP if possible.
However, IIS 6 is not installed but seems very easy to add. MsSQL 2005 would have to be purchased (I think), so it looks like I'll use MySQL and PHP - Non-thread-safe version with FastCGI seems a good option, I hope?
