Resolving external domain using local servers fails

[Per Weisteen]

I've got a problem resolving www.cooltravelassistant.com using my
internal name servers. Most other domains resolves ok. What could be the
problem ?

hk9perw at vkhdpc06 ~ (rc=0)> nslookup -q=ns cooltravelassistant.com.
Server:  vkhdsu01.hda.hydro.com
Address:  136.164.216.11

*** vkhdsu01.hda.hydro.com can't find cooltravelassistant.com.:
Non-existent host/domain

Then I checked what nameservers were listed in whois and tried one of
them :

hk9perw at vkhdpc06 ~ (rc=0)> nslookup -q=any www.cooltravelassistant.com.
207.46.138.10
Server:  dns.cp.msft.net
Address:  207.46.138.10

www.cooltravelassistant.com     canonical name = cooltravelassistant.com

cooltravelassistant.com internet address = 207.46.184.75
cooltravelassistant.com internet address = 207.46.184.70
