Hi!
Do you think installing moodle this way is safe? AFAIK, Windows 2000 does not have built-in (and enabled!) firewall and catches viruses easily; Moodle with XAmPP package contains phpMyAdmin which may also contain vulnerabilities. Such server can be a very good target for ko0L h@Ck3rZ, so I'd advise you to pay much attention to protection of this server.
