The D-link router is an integral router and DSL modem. ISP requires PPPOA
which is what i have the router configured to.
Thanks for your thoughts on the topic. I will keep digging; there must be a
logical solution somewhere.
Robert Aldwinckle has taken me to task for overlooking something. The
possibility that your system is seeing your DNS servers as local. You can
see this by using the 'nslookup' command in a command window. For Windows XP
type 'cmd' in the Run box. Windows 98 and Windows Me have a shortcut in the
Start menus.
I get the following result:
| C:\Documents and Settings\Norman>nslookup
www.yahoo.com
| DNS request timed out.
| timeout was 2 seconds.
| *** Can't find server name for address 192.168.0.1: Timed out

There is a perceptible delay between pressing the 'Enter' key and seeing a
result. What is happening is that my DNS request is passed through my
Netgear router to my DSL modem. When I run 'ipconfig -all' at the command
prompt, I get the following:
| C:\Documents and Settings\Norman>ipconfig -all

As you can see, Windows thinks that there is a DNS server at 192.168.0.1,
which is the IP address of my DSL modem. I can override the DNS server
setting in the router by manually adding the DNS servers listed in the
modem. When I do, 'ipconfig -all' gives me this result:
| C:\Documents and Settings\Norman>ipconfig -all

The DNS servers are now the ones listed in the modem Connection Information
page at
http://192.168.0.1. Now 'nslookup' is a bit faster, almost
instantaneous:
| C:\Documents and Settings\Norman>nslookup
www.yahoo.com
| Server: dnsr1.sbcglobal.net
| Address: 68.94.156.1

Since this all works for me, anyway, I never give it much thought. Although
I don't know how a combination unit handles the matter. Maybe I do; the
relevant result from a computer which I know for certain to be connecting
through a combination DSL modem/router:
| Ethernet adapter Local Area Connection:
|
| Connection-specific DNS Suffix . :
| Description . . . . . . . . . . . : Realtek RTL8139 Family PCI Fast Ethernet NIC
| Physical Address. . . . . . . . . : 00-40-2B-62-51-E9
| Dhcp Enabled. . . . . . . . . . . : No
| IP Address. . . . . . . . . . . . : 192.168.1.254
| Subnet Mask . . . . . . . . . . . : 255.255.254.0
| Default Gateway . . . . . . . . . : 192.168.0.1
|>>>> DNS Servers . . . . . . . . . . . : 192.168.0.1 <<<<|
| 206.13.28.12
So, if your 'ipconfig -all' result shows a local IP address
(192.168.xxx.xxx) for your DNS server, you might try to identify your DNS
server IP addresses (should be available through the router status pages),
and adding them manually to your Ethernet adapter through Network
Properties.
