How does MPA connect over the Internet?
For Office XP family products, activation over the Internet requires users to have their own Internet service provider (ISP) connection. Users who do not have an ISP connection have to activate by telephoning a customer service representative. For Windows XP, users who do not have an ISP may use the Microsoft ISP network to activate. Users who do not have an ISP and cannot use the Microsoft ISP network have to activate by telephoning a customer service representative.
