Can you ping the FTP server ?

In a regular Command Prompt
Ping does not seem to work on the domain names or the FTP servers for
them.

Do you know how to change the MTU in windows (temporarily) ?

If you want the third option, it's still here, in the Legacy Tools section.
Normally your value might be 1500 or so. I can't check my WinXP right now,
as I'm doing maintenance on the WinXP drive :-( And I'm on Win8.1 as punishment.

What would that do for me?


That's a workaround for a Black Hole routing
problem caused by the server end having ICMP
turned off and your MTU happens to be too big.

Apparently there is a modification to TCP/IP in
later OSes, to fix that somehow. But I don't think
it's present on WinXP.

Another thing you could try, is to use Wireshark
packet sniffer and see whether any RST packets are
being sent (they show as RST in Wireshark). As those
can be a legitimate part of protocol that says the
server doesn't have sufficient resources and would
like to close the connection.

None of your evidence suggests that's what is going
on, but I had a three month stretch where my ISP
was randomly sending those. Right after they bought
a Deep Packet Inspection box...
