Here is what I got:

#1:

C:\>nslookup -qtype=ns sun.com 192.168.1.6
Server: svr-ad1.ppenet.com

Non-authoritative answer:
sun.com nameserver = cbru.br.ns.els-gms.att.net
sun.com nameserver = cmtu.mt.ns.els-gms.att.net

cbru.br.ns.els-gms.att.net internet address = 199.191.128.105
cmtu.mt.ns.els-gms.att.net internet address = 12.127.16.69

tracert returns: "Unable to resolve target system namewww.sun.com"

OK, let's find out who is telling your DNS it is no existent.
Check the answers from the commands and post exactly what the answers are.

Run these.
1. nslookup -qtype=ns sun.com <IPAddressofLocalDNS>
2. nslookup -d2www.sun.com

1. should be:
W:\>nslookup -qtype=ns sun.com 192.168.201.13
Server:  dc01.office.wftx.us
Address:  192.168.201.13

Non-authoritative answer:
sun.com nameserver = ns1.sun.com
sun.com nameserver = ns2.sun.com
sun.com nameserver = ns7.sun.com
sun.com nameserver = ns8.sun.com

ns1.sun.com     internet address = 192.18.128.11
ns2.sun.com     internet address = 192.18.99.5
ns7.sun.com     internet address = 192.18.43.15
ns8.sun.com     internet address = 192.18.43.12

2. Should have this in the final answer after it goes through the DNS Suffix
search list.
