Is there any way to get the DNS service on my Win2K test server to forward Internet DNS requests to a Linksys BEFSR41 router? I've been trying to do that as part of my efforts to learn DNS configuration in preparation for the 70-216 exam; the address is resolved, but nothing can come in (PING returns 4 empty packets).

Or, should I just be setting the Default Gateway to the Linksys router, and using the DNS service only for resolving local names in the domain?

Any assistance is gratefully appreciated!

Could you provide a little more clarification? I’m not sure we have enough info about your network setup.

In the mean time, check out the following and see if it helps:

We have the same discussion going on under the NAT thread. Check there.

It seems to me that if the address is resolved as you said, then DNS has done its job. Perhaps there is something else wrong, or the node you are pinging is down (although I would assume you tried more than 1). Good question! Good luck! I'd be interested in what you find out.

I had the same symptons on a machine that had been configured on a network with a proxy server. I'd taken it home, and tried to get it to connect to my dad's dial-up ISP; the DNS was working, as evidenced by PING results, but the PING's never returned any data. Removing the proxy server and reconfiguring the Internet options fixed the problem.

If your DNS server is configured as a root and you ping an address outside of the zone you will get the response that you mention. You need to find a way to forward queries to an outside server, preferably the DNS servers provided by your ISP. As I mentioned in another thread, delete your root zone, make a new zone that forwards to your ISP's DNS servers.

Here is an image of my DNS zone settings - do I have a root zone configured? I thought a root zone was something like myzone.com, not test.myzone.com.

Forgive me for sound dense; my DNS knowledge is still pretty elementary right now.

Hey, cool dude! No, I don't see a root DNS zone. Still would like a little more clarification though.

You said the address IS RESOLVED. To me, that means one of two things if the ping still fails:
1. The machine you are trying to reach is down or the network failed somewhere inbetween the two.
2. The DNS server gave you the wrong address (which could mean that the query went to the wrong DNS server, I suppose, but would the wrong DNS server give you back an address at all?!)

I think the Linksys router has a firewall that may be filtering out the responses.

Anyone here familiar with Linksys routers?

This is all largely academic, seeing as I am past both 70-216 and 70-217, but still, I would be really interested in finding a resolution, just for curiosity's sake.
