Hi Listers,
Strange situation here or maybe I'm having trouble seeing the forest for
the trees...
Two external DNS servers, both running 9.2.1 and Solaris 8. One is a
master and one is a slave. Both have identical named.conf files (with the
exception of master/slave specifications in the zone areas). Using
nslookup, one can resolve a hostname and the other cannot. Using dig,
both can resolve the hostname. I was hoping someone could shed some light
on why I'm seeing this behavior. The hostnames in question are
holidaysentinel.com and www.holidaysentinel.com. See below:
Server that can't resolve:
# nslookup -sil holidaysentinel.com

# nslookup -sil www.holidaysentinel.com
