The problem is fixed. The router needed to have a firmware upgrade.

Normally the DHCP server is running on the router, not from another device on
your network (Win2003 in this case.) And you never want two DHCP servers
running on the same LAN.

You can verify whether it's a DNS issue by using IP addresses instead of
domain names. For example, instead of using "ping www.google.com" use "ping
216.239.37.104". If you get a response from the latter but not the prior
then it's a DNS issue. Otherwise it's a routing/connection issue.

You can also try to ping your static Internet IP address from an outside
client (one of us could try.) If that doesn't work then your router isn't
even visible on the Internet.

We decided to get a static IP address because we have a VPN set up between
two locations, and were having problems when the IP address changed.
We are using a static IP address through Qwest and the other location, and
have not had any problems.

I did have the fixed IP address in the router. The ISP asked me to set it
up to Automatic DHCP amd the static IP address would be be picked up by the
router. Either way, the internet cannot be accessed.

Te workstations look to the local server for DNS, and get ip addresses from
the Server. I have set up networks the same way , and have not had any
problems.

The laptop does not have athe fixed IP address, it is getting it through
DHCP.

since. I talked with Linksys, and they said it was a DNS problem with
the provider. The provider thinks it is the router. I tried another
router with the same results. I can ping the static IP address and teh
gateway, but cannot ping the ISP's DNS servers or any ip addresses on the
Internet. I am very frustrated!!!
The ISP can see the Cable Modem, and if I connect directly to the Modem
with my laptop, I am able to get on the Internet. If I try to get out
with my laptop going through either router, no Internet. Help!!!!

The server is running DNS and DHCP!

Does anyone have any ideas!

Thank you for your help in advance!!!

It sounds like you have the router(s) set up wrong. You probably want
the router to have the fixed address as its WAN address (why you decided
to go with a fixed address is beyond me -- it's probably not worth
whatever extra you're paying for it unless you have a specialized need,
and if you did, you'd know about all this), and then provide local
addresses to the laptop, etc. via LAN-side DHCP. You also need to
figure out who is responsible for login protocols (e.g. the cable modem,
the router, or the laptop) and make sure all the devices honor that
decision.

If you've set your laptop to the fixed address when the router is in
the tree, that's your problem -- you don't understand what a router is
for.


BTW, are you by any chance running ICS? And what does your network
topology look like?

And how are DNS and DHCP configured on the W2003 server?
