You are the second comcast customer recently to experience DHCP failure
on this group. The other poster is using comcast without a home router,
so the problem is between XP and comcast. Yours is between XP and Netgear.

I wonder if you recently updated to XP SP2? What software did you
recently install or uninstall? Have you recently removed spyware with
Spybot or Ad-aware? Were there any Windows critical updates installed
just before the failure?

At this point, there is no solid clue except that it seems that it is
strictly a DHCP problem, since configuring an appropriate static IP
address confirms that TCP/IP is working and Internet access is OK. I'm
off to google the problem, let me know if any of the above questions
raise a suspect.
