macbook pro ethernet non-op in 10.5.2
My ethernet connection (en0) appears to have given up the proverbial ghost.

It can not obtain a valid DHCP address, my DHCP server is completely functional.
It can not connect when given a manual IP address.

I have booted off of the install CD and gone to utilities, at which point my ethernet adapter does get a valid DHCP issued IP, and can ping the world.

Is my only option at this point a reinstall of Leopard?

Edit, I've already reset the p-ram, and turned the if off and on repeatedly. This became an issue suddenly, this evening. The only system change was a safari update, but even my normally suspicious of system changes mind finds that one a stretch to have an impact.

well, the fix was to trash /Library/Preferences and reboot.
