I've been caught up ... let's try and sort this out!

From what you've said I infer you have computers:

WS1 - IP = 192.168.0.17  (problem computer) WS2 - IP = 192.168.0.50 
(working computer) WS3 - IP = 192.168.0.9    (Winproxy to Internet and
proxy DNS).

On WS1and WS2 you have IP of DNS server = 192.168.0.9 and you have default
gateway the same IP. At WS1 (and maybe WS2) you have a additional two DNS
servers. Possibly not helpful because I would think that if 192.168.0.9
doesn't work then no other DNS server is likely to help either. However,
that is nor relevant to the current situation.

You ran nslookup at command prompt on WS1 and it said that there was no
response from the DNS server 192.168.0.9. That sounds like a firewall issue
on WS1 (given that WS2 has no trouble using WS3 as its DNS server, and WS1
can ping WS2).

So, do you have firewall software installed, or any other form of IP
filtering? Have you ever had such software installed?

At command prompt on WS1, what happens when you run: ping 192.168.0.9
ping 4.2.2.2
