Our network served by 65.116.161.134 cannot display the web site
served by
164.121.249.14. Below is results by my ISP looking at my firewall when
my client machine tried to hit the 164.121.249.14 server. Any ideas as
to what or where I need to look.
Thanks in advance

It's a problem with the site itself; I can't access it either. Looks like
it's trying to redirect you to a site that doesn't exist, namely
"/en_US/deerecom/usa_canada.html". Note that your browser interprets this as
an absolute address, not a relative one.

Try connecting to port 80 of 164.121.249.14 and try it yourself:

GET / HTTP/1.1
Host: 164.121.249.14

HTTP/1.0 200 OK
Connection: close
Server: Netscape-Enterprise/4.1
Date: Tue, 22 Apr 2003 03:13:43 GMT
Content-type: text/html; charset=utf-8
Content-length: 77

<META HTTP-equiv="refresh" content="0; URL=/en_US/deerecom/usa_canada.html">

Note that if you specify your protocol as HTTP/1.0, it will return a page
redirecting you to "http://siteunavailable.deere.com".
