I guess I wasn't really clear. I didn't mean to suggest that he 'should'
use any nameservers other then his own ISP's. I only sent him mine
to show him how to set up resolv.conf. I personally change my DNS
entries each time I have switched ISP's.
As fas as the "Danger, Will Robinson!" goes, it wouldn't take a rocket
scientist to figure out your ISP had changed nameservers, would it.
Then again, with some of the questions I see on this list, I should be
clearer in my replies, just in case.
Thanks for the hint.
