Is it a DNS problem?

We have internal and external dns servers (2003). We can browse and do
nslookup on any sites except for sites that are hosted by
"clearchannel.com".

Clearchannel has the following dns and web servers and they host many radio
and tv stations on the same web servers:

dns servers:
dns1.clearchannel.com
dns2.clearchannel.com
ns1.clearchannel.com
ns2.clearchannel.com

web servers:
207.230.150.254
207.230.154.254
207.230.156.254

Here are some of their sites that we cannot get to:
www.kbig104.com
www.foxsports610.com
www.y92.com
www.talk960.com


When we do an nslookup we get the following:
DNS request timed out.
timeout was 2 seconds.

We can get to their sites using our separate dsl line that we use for
testing.

We have no filtering set in our firewall for their ip addresses. Could this
be an issue with our dns? Any help is appreciated. Thanks!

Richard
