Internet working, LAN not

[gs3user007]

I recently was monkeying around with some DNS settings on my router (switching to openDNS). Everything seemed fine. My XP box could still connect to the internet, as can my linux box. Something has gone horribly wrong though. My boxes could no longer communicate with each other.

I've done a little troubleshooting to try and figure out what happened... And the only nugget of helpfulness I can find, is that my XP box can successfully ping my router, while Kubuntu cannot.

I'll run whatever utilities you give me explicit instructions to run, give you whatever output you need to see. I'd really appreciate if they could communicate again (they can't communicate, so i can't share files between them, becoming a problem).

Thanks in advance! The forums have always been very helpful in the past.

Some info off the Kubuntu box:

If there's anything else you need to try and diagnose and fix the problem, let me know please.

Re: Internet working, LAN not

try adding the ip number and names for the computers on your lan in /etc/hosts. I'm sure you are not running a lan at IBM so there will not be that many entries. And I do think windows has a hosts file. They ripped off their TCP/IP stuff from freebsd so I suspect they do.
