Strange case of ping time-out

We have a single .local domain under AD of about 35 workstations running
fully patched XP SP3, and 2 servers running fully patched 2003 Standard SP2.
All hosts have internet access via a Cisco firewall which connects to a
broadband router. They are all functioning properly except one workstation.
This HP-Compaq d330 microtower cannot access the Internet via IE7.
Investigation shows that when it tries to ping anything outside our
192.168.1.x subnet it times out. All shares, printers, and server functions
on our LAN are accessible.
Comparison of 'ipconfig /all' and 'route print' responses between this
workstation and a d330 which can access the internet shows no differences
other than name, IP address, and MAC address. All our hosts get DNS and WINS
from the 2 DCs, and use the Cisco firewall as gateway.
%system%\drivers\etc\hosts is the default version, identical on all.
Machine is free from malware as far as McAfee AV, Microsoft MRT, and
Malwarebytes can see.
I am at a loss how to proceed with this problem. I am reluctant to flatten
and rebuild as it has some apps used by our engineers where we do not have
CDs and which may no longer be available to download.
Sherlock Holmes said "Once we have eliminated the impossible, that which is
left must be the case, however improbable". Right now I am out of improbable
ideas.
