DNS Resolution Problem

Hi,
We seem to be seeing a problem with our cache-only servers (BIND 8.2.2-P5)
resolving Internet domain names. On one server (sngona1), we can resolve the
name, however, we get a connection timed out on another server (sngona2).
This appear to occur for different domains with no fixed pattern. Anyone has
experienced this before?
Some nslookup and dig outputs ...
# nslookup
Default Server: sngona2.cns.hp.com
Address: 15.2.177.10
> ges.com.sg
Server: sngona2.cns.hp.com
Address: 15.2.177.10
Name: ges.com.sg
Address: 203.127.111.75
> set q=mx
> ges.com.sg
Server: sngona2.cns.hp.com
Address: 15.2.177.10
*** sngona2.cns.hp.com can't find ges.com.sg: Non-existent host/domain
