I had taken my iBook to a meeting where I plugged it into the clients local network. Everything worked fine, I was able ot connect to the Internet, basically no problems. As soon as I got back to the office though, my iBook will no longer connect via my cable modem.
I've swapped out network cables, reset my cable modem, logged out multiple times, even restarted a couple of times. All to no avail. It refuses to get a valid I.P. address from the server. I know its something with this particular machine as I have another Mac in the office (the one I'm typing this on) which is experiencing no problems connecting.
Any ideas or tips would be greatly appreciated.
