Can no longer Obtain IP Address Automatically In WindowsXP

[jmassa53]

Hi folks. I have several PCs on a home network via a Linksys router.
They are all configured to obtain the IP address automatically.
Suddenly today, one of them says the network connection has "little or
no connectivity" and it won't connect to the other systems or the
internet. The other computers are working fine, so it's not the
router.

I checked the router and if I assign this PC a static IP address and
DNS server, it connects fine. However, as this is a laptop, I need to
be able to have mobile wireless access, so I need the automatic IP
address to work. Any suggestions? Thanks.

Just because the other computers work fine doesn't mean the router
doesn't have a problem. Unplug your router from the wall, count to 10,
and plug it back in again. It's very possible that will fix your
problem. I have a Linksys router and I have to do this every third
month or so.

HTH,

Could the router DHCP server have a limited scope, or MAC address filter in
place?

I presume that the DHCP client service is running on the computer? If so, your
next bet is LSP / Winsock corruption.

John:
Thanks for the suggestion. Unplugging the router fixed it. I thought
of this early on , but forgot to try it. Thanks!
