Question: Andrew - Thanks! That did indeed let us get out to the net again. I did try to read the article you noted - but, tongue in cheek - it is all Greek to me (they make us preachers learn Greek). If you have time and / or energy - can you put in a few english words, what my problem really is? Either way - i left the dns modified and the office staff is smiling again, albeit, perhaps, temporarily.
Thanks,
dave

Question -
Andrew - God bless u if you can help, and thanks even if not!
We're running a 25machine network using a Win 2000 server connected to the net via a cable modem and a zywall 10 firewall.
Even though everything can "see each other," we can't get out to the internet through that firewall.
Seems our problem is dns related, cause while I can ping ip addresses in house and on the web, i get unknown host when pinging google.com etc.
Do you have any knowledge of where / how I address this in / on our server? It is set up as a dns server and resolves our in house machine names. But I'm at a loss to understand how things got "broke" and how to get backin touch with the outside world.
Any help or references you could provide would be wonderful. Thanks!

I ran into something very similar recently. First, try changing a workstation to use 129.250.35.251 as the DNS. See if the machine can connect to the internet. If it does then but the DNS back and read this article. rel="nofollow"www.micahvaline.com/blog/archives/2004/12/edns0_windows_s.html
Let me know how that goes. I will be glad to keep helping as you need it.
Answer: Well that answers at least one question. As a short temporary fix you could load WINS on the server and point all the workstations WINS settings there. That way you can still get name resolution. You don't want to leave the setting the way they are because you will start to loose internal resolution and might not be able to see the server properly. The WINS will at least prevent that to a large degree.
Anyway what we really want to do is fix the DNS instead of hack around it. I assume that you have already tried restarting the server. Sometimes DNS just hickups. Also make sure all the service packs are installed on the server. Some of them fix DNS server issues. windowsupdate.microsoft.com
The article I sent you shows how to fix a firewall problem. If you have a PIX I recoment adding the registry entries that it talks about to your server. If you don't have a PIX firewall then it must be some other DNS issue. Try setting 129.250.35.251 as a forwarder and set a workstation back to use the server as DNS. See if they can get to the Internet then. |
