Wondering if someone might know how to point me in the right direction.

Somehow, my setup no longer can resolve domains. (ie: www.google.com) from ping or from a browser, etc. But, I can ping the ip addresses just fine. And, no -- it's not the /etc/hosts file. I literally can't access any urls period...

Perhaps something to do with the latest updates -- and it knocked over some sort of network configuration settings? (I keep my system pretty up to date generally)...

Anyone know where I should look?

I was looking at this url for some ideas... http://oreilly.com/catalog/linag2/book/ch06.html
stuff like "name resolution", "resolver config", etc. but this stuff is new for me.
