Can't resolve one domain..

[Bill Anderson]

I am having trouble getting my dns servers to resolve a particular domain.
They work great  except for this one domain:

gulfstream.com.br

Other DNS server seem to have no problem resolving this domain.  Any ideas
on where I could start tracking this issue down?

I am running bind-9.2.1-1.7x.2.rpm on RedHat Linux.

Here is the error message I get:

# dig gulfstream.com.br
; <<>> DiG 9.2.1 <<>> gulfstream.com.br
;; global options:  printcmd
;; connection timed out; no servers could be reached
