Recommendations on WP Windows Installation

I have to install WP on a Windows 2K or 2K3 server. They want to keep IIS also. This machine would only be running WP so I only need what WP needs (and phpMyAdmin).

I was looking at a package like XAMPP. It seems all PHP/MySQL installation kits, i.e. XAMPP and WAMP come with Apache. Can I still use IIS or are there other kits that don’t include Apache?

Are there any advantages/disadvantages to running IIS (I know I will have to hack the mod rewrite stuff, are there additional features the IT staff will want to keep from IIS).

Any other advice for a programmer who does not have experience with server setups and admin would be appreciated.
