Hal -- Without some details, I doubt anyone here is going to be able to help you. To the extent that the problems derive from details of Windows XP ... well, this is a Linux list, so I doubt we'll be of much help at that level in any case.
First, what is the address? How stable is it? (What I mean is that cable modem ISPs usually use DHCP to assign addresses, and in some cases the leases have amazingly short lives, even as short as 15-30 minutes between address changes.) For ISPs to use Class A addresses isn't that odd, BTW; I see a lot of 24.b.c.d adresses, just as an example. Second, what are the symptoms in the failures? When telnet or ping fails, it usually does so with some sort of error message, and the error message tells one (if one is experienced) something about the likely source of the problem. If they fail silently, there is usually a delay before they fail; knowing roughly how long it is is also informative. I'm not sure what you mean by "the 'new' lashups", but if ping has become obsolete, it is news to me. Third, what does "traceroute" tell you? Where does it stop? Fourth, when you are connected, can your son ping you? Can you ping other, known-good sites (big names, say, or even me, if you need a target)? Can he? In any cases where the answer is no, what does the failure look like? Fifth, I'm no Windows expert (though I do use Windows machines) and I've never run XP. Is your son sure he is running a telnet server on his machine? (I'm putting aside for the moment the usual concerns about the safety of using telnet in the interest of troubleshooting the immediate problem.) If you are running a telnet daemon, can he telnet to you? Sixth, does your son run any sort of firewalling package on his system? If so, might it be interfering with connectivity somehow?
