I have used dnsmasq and found it easy to setup (although in your situation you would need a separate resolv.conf) sounds silly but have you checked the dns server, is it resetting the ttls of the values its sending out ? I would probably set the machine into single user mode, make sure nothing else is running and then start with the pings and do a tcpdump -pni eth0 -vvv port 53 or icmp. try a host -v google.com or a dig google.com work it from there Alex > > Right now I am trying number 2.
