DNS resolving question

[Eric Wood]

Running FC6.  Would anyone know why my DNS server
# nslookup
>  e.staples-deals.com 
;; Got SERVFAIL reply from 10.0.0.1, trying
next server
;; Got SERVFAIL reply from 66.83.182.3, trying next server
Server:         66.83.182.4
Address:        66.83.182.4#53

And evey when I re-prioritize my nameservers in /etc/resolv.conf, I get:

>  e.staple-deals.net 
Server:         66.83.182.3
Address:        66.83.182.3#53

** server can't find e.staple-deals.net: NXDOMAIN


No other host or domain has a problem:
>  staple-deals.com 
Server:         66.83.182.3
Address:        66.83.182.3#53

Non-authoritative answer:
Name:   staple-deals.com
Address: 204.13.160.25

Any ideas?
