Hi Don,
It does not appear that routing is the issue here. It is more likely to be DNS if you can ping the site by IP address and not by name. One way to troubleshoot would be to use the command 'nslookup' on a machine on your LAN. Once you enter that, type in the DNS name of the site that you are trying to access. I suspect it will not resolve to the right address.
E.g
C:\>nslookup
Default Server:
Address:
> www.cisco.com
Server:
Address:
Non-authoritative answer:
Name: www.cisco.com
Address: 198.133.219.25

I am not sure what you mean by "quenched", If you can expand on that, that might also help.
Cheers,
Paresh
