I have a machine that didn't get an IP from my home network via DHCP. Had
the same problem on another network, so we popped in a wireless nic and
tried it. They both fail (Getting only as the addy).

Nics both show as connected, so I assumed it was the stack. Resetting the
stack didn't help.

I don't think the firewall is on, nor tcpip filtering.

Any crazy fixes (I am about to swap hard drives to see, but it doesn't seem
to be hardware)?
