Pretty much always worked for me. I'm one of the guys that sets things 
up so that guys like you have no reason to ever say "Around here, 
Comcast's DNS servers are famously bad". Replace "Comcast" with the real 
name of my real employer. If my team gets that wrong (and we never have 
thus far), millions of people immediately and at once suffer. So forgive 
me if I'm a tad touchy on the subject.

But seriously, if the dns servers provided by dhcp aren't up to snuff 
then by all means put working ones in your resolv.conf. And also help 
the owner of the network fix his config - there really is no excuse for 
setting up software to tell people to use broken or badly behaved caches.
