2. Mox's NTP server isn't a "real" server. When I ran the scan against my XP box with no firewall, (Mox, you were in the DMZ you said so you are unfirewalled), it also found an NTP server.... I think the box is just responding with a request for it's system time and they report that as a server - Comments anyone.
Nope....I was on a stand alone system, on dial up and using Kerio firewall.
