help DHCP problem

[notme]

I am using windows XP pro with cable modem. It has been working very well for four month. But suddently today, my connection is dead.

It seems the problem is that the DHCP server couldn't get an IP from my ISP.

The problem should be on my computer. When I unplug the cable from my computer, and restart it. The connection icon still shows up in the right-bottom corner as connected. (before, it showed "disconnected icon")

and in the event viewer, it has a warning message: event number 1007.

Please let me know how I can fix the problem.

disconnect the power from your cable modem.
shut down your computer.
boot it back up with the cable modem now turned on.
open a command prompt

issue this command:

ipconfig /release

now, keep issuing this command (about once per minute) for about 10 - 15 minutes:

ipconfig /renew

if you don't get an IP address that isn't in the range 192.168.x.x (and with no gateway) then your cable modem is indeed NOT getting an IP address from a DHCP server (your provider).

Investigate the cable (try another one), failing that call your ISP maybe they are having problems on their end.
