for some reason, we are no longer able to access certain sites through
the proxy server.
for instance, is not accessible through the proxy.
I can bypass the proxy to access the site with no problems.

DNS servers are reported as up. They are the same ones my workstation
uses to lookup the site. proxy server can resolve to
the ip address, via ping or nslookup

server = nw6.5sp6, just applied latest wsock patch
