As long as XP cannot obtain a DHCP signal from your ISP, you will be
unable to repair the connection. Contrary to your ISP's NOC support
person's statement, your ISP must provide this signal. ONLY their
DHCP server can provide a new IP for your modem, or renew your current
one. So it IS their fault. If their DHCP server goes down for just a
second, you will lose your IP, no matter how quickly they get it back
up.
Your IP probably expires every 24 hours (this is usually the case with
most Cable connections (Dynamic IP provided by their NOC via DHCP),
unless you specifically purchased a static IP from them.), and so must
be renewed from time to time by the NOC. If your machine does not
receive a DHCP signal from the NOC, you will never get an active IP.
It is also possible that you have set your modem to somehow expire
your IP every 24 hours. This is especially true if you have a static
IP.
It is also possible that your Winsock has become corrupted.
