I have seen the router settings changed to only have 1 or 2 DHCP addresses
available.
But by typing the address into the window, you should be able to ping the
router.
I have also had to remove/uninstall the NIC (ALL of them) from device
manager and reboot.
Once it finds & reinstalls the NIC, it re-establishes the DHCP settings
automatically.

I have a real head scratcher here... I've been banging my head against the
wall for a couple of days now. I've stumped a friend at work who is an
MCSE, and I'm just about ready to wipe the system and start from scratch.
This is what I'm really trying to avoid.

I have a Windows XP Home Edition system with SP2 that has been running
fine for several months. This is connected to a Linksys broadband router
that does DHCP. Let me stress that this configuration has worked
flawlessly for months. The system is a custom built, that I built myself.
The motherboard is an Abit AB9 Pro that has a pair of built-in GigE
network ports.

A few nights ago everything was working fine. The next morning I had no
Ethernet connectivity. I specifically mean I had no Ethernet connectivity
because my work laptop is connected to the same Linksys router and is
working fine. I tried step one of Windows troubleshooting and rebooted.
This obviously didn't work. I disabled DHCP and assigned a static IP. I
was able to ping the IP I just assigned to the card, but was unable to
ping the router. I replaced the Ethernet cable and rebooted and still
nothing.

At this point I thought maybe I have a bad network port on the
motherboard, so I went out and bought a brand new Linksys Ethernet card.
I installed this and it would also NOT pickup a DHCP address. I assigned
a static IP with the same results. Out of pure frustration I went out and
bought a new broadband router, and this too made NO difference. Obviously
several reboots have occurred in this time.

I ran this by an MCSE friend at work. He suggested doing a repair install
of Windows XP and this sounded like a good idea, although I'm still stuck
without Ethernet connectivity after this. The only thing left that I can
think of is to give up and either call Microsoft (I'm not paying the money
for that), or wipe the system and re-install from scratch. The last thing
I'm going to try this evening to completely rule out hardware is to
download a Live CD version of Linux and make sure that I have network
connectivity that way. I suspect that this is some kind of TCP/IP
corruption, but I have no idea how to straighten this out.

Please help me avoid having to wipe and reload the system. I know that
this being Windows I need to do this once a year or so, but I just built
this system less than 6 months ago. Even Windows should be able to run
without having to be reloaded for that period of time. Thanks in advance
for any help.
