[olug] DNS issue

[Terry]

Hmmm..

nslookup<enter>
server=204.26.64.1   ### This is a qwest.net DNS
Server
www.yahoo.com

Does this work?

If not, your client is foob'd.  ( I doubt it cuz you
have multiple clients with a problem but could be a
firewall issue with regards to the client(s).)

I would also do some nmapping to find out if the
require ports are available....

nmap -sU -p 53 ip.address.of.dns  (careful, I am not
sure if this is bad practice or not)  I would do it
but that doesn't say a whole lot...haha
