 There are several reasons XP can drop a DHCP lease. I doubt it would be an ISP
issue, lest most of their clients in your area would be having the same issue
and calling to complain (defective router, DHCP server, TFTP server, etc.)

 XP can be especially tricky to "fix" DHCP issues because the TCP/IP protocol
and WinSock cannot be easily reinstalled if it is corrupted. So if the transport
is damaged, well.. that's a pain in the ass.

 Easiest solution is, if it was working a few days or weeks ago, is to go to the
start menu and find "system restore" and restore the config to a working date.
I've seen this easily fix the problem. Any newer data is not deleted, just the
XP config is reset to that date. Saved my ass many times, worth a shot.

 If your networking config is set to use a static IP address or DNS (or several
other even more technical settings) then a problem like this can result. Have
the techs at the ISP walk through all of your networking settings to make sure
it is configured correctly.

 If that don't do it, see if this does any good:
1. Start --> run, type in "CMD".
2. "IPCONFIG /release"
3. "IPCONFIG /flushdns"
4. "IPCONFIG /renew"
5. "IPCONFIG /registerdns"
6. Reboot.

 If it still doesn't work, you can try these. Warning - you should make a system
restore point first, as these are destructive procedures:
1. Start --> run, type in "CMD"
2. "netsh int ip reset c:\resetlog.txt"
3. Reboot.

To reset your windows sockets, download and run the following:

5. Reboot.

 Try removing all network adapters from device manager and then reinstalling.
Here is a "trick" used to show defective drivers which otherwise would not be
displayed, not even with "show hidden" in the devmgr:

6. Start --> Run, CMD
7. Type the following lines exactly from the command prompt (misspelling won't
generate an error):

    SET DEVMGR_SHOW_NONPRESENT_DEVICES=1
    START DEVMGMT.MSC

9. In the window that opens, Click View/Show all hidden devices. You may see
transparent icons under Network Adapters - remove all these (uninstall) along
with your modem NIC and reboot to allow windows to reinstall the correct driver.

 Hope that helps.
