WordPress server requirements for Versions 2.1, 2.2, 2.3:

Recommended setup

We recommend Linux with either the Apache or NGINX web-servers as the most robust platforms for running WordPress, but any server that supports PHP and MySQL will do. If your host doesn't support one of these platforms, and mod_rewrite, you will probably be better off switching to one of the many hosting providers that do offer those choices.

It is also essential that your host allows remote connections.
