network problem, stopped working

[eemerge]

I've been using iatkos for several months , everything worked fine...

Today, i ran into a little problem. im sharing the internet connection on iatkos with a laptop. Until today all was FINE, today the laptop didnt communicate with the desktop . I checked cable, everything...all were ok.

Before i rebooted iatkos, i had internet. After reboot, the main network card (connected to the ISP modem) just doesnt want to get its IP via DHCP. I keep getting 169.bla bla. Also, another strange thing i cant 'connect' the laptop with the desktop.i even tried entering addresses manually.

So my guess is something is bad with the network on Mac OS. But i cannot figure it out since everything seems ok there., no problems reported no nothing.

Any help would be appreciated.

Thanks in advance.
