Re: Slow DNS Lookup (4TH POSTING)

leonard, it's hard to say since i have next to no info, but it sounds like
you may want to look at tracerroute, ping and tcpdump.

these three utilities, when taken together, can diagnost just about any
network problem.

(you may need to see output of tcpdump on the DNS server).
