Windows server installation

Hi everybody, I need an advice.
I am planning on installing Postgresql+postgis on a windows server machine.
I would like to hear from you which one is the best between Windows 2003
server and windows 2000 server in terms of various issues related to
POstgresql or postgis.
Thanks, Simone.
