Internet connection issues on a Win XP Professional work station..

I have a computer connecting to a domain controller, accessing Exchange,
Access and other network related applications. All work without a problem.

As of recently, the computer will not connect to the web. It obtains an IP
address via the DHCP (internal) server and DNS (internal) with no issues but
still can't connect. When I try pining external domains or ip addresses, it
times out. I've tried repairing the IP, flushing the DNS, stripping all
startup items, manually entering the ip address and DNS server address and
switched it back to auto since that didn't resolve the issue. I've searched
and can't find a solution. I thought maybe it could be the server but the
server is functioning fine and serving 25 other users who are connecting
through it's DHCP and DNS servers. We're using W2K3 SBS.

Short of re-installing Windows XP, is there any other things I could try
before going that extreme?

Thank you!

Your symptoms are consistent with being provided internet access
through a proxy server. Make sure your browser is configured properly
for your proxy.

For IE: Tools->Internet Options->Connections->LAN Settings

Our ISP is not Verizon/GTE. The backbone/T1 Leased line most likely is though
(through Telepacific).

I stopped the test after 10 attempts...

Tracing route to vnsc-pri.sys.gtei.net [4.2.2.1]
over a maximum of 30 hops:
