First, are your XP machines behind a firewall, or does your dsl just plug

computer or a firewall. You want to retrieve a reply from each hop in
between the locations. If a bunch of them timeout then you may have found
some more information to troubleshoot your problem.
Thirdly, if you do have a router/firewall inbetween your dsl modem and your
computer, at either end, make sure that this device is configured to accept
