Lion doesn't seem to be giving out DHCP addresses when I turn on Internet Sharing. My firewall is off, I create a shared network with no security sharing ethernet->wifi. In Network Preferences the Wifi connection shows as yellow, with a self-assigned IP, and any device I try to connect (e.g., iPad) doesn't get an address. Help!
I finally figured it out.
Hope this helps!

I turned off all internet connection sharing.
I deleted the following files:

Turned on internet connection sharing
This resulted in Internet Connection sharing giving the client the correct DHCP lease details.
