NT Workstation not using DNS

Locked

I have an NT Workstation (laptop) where DNS is no longer working (I get a “bad IP address” when trying to ping names, and a “server not found or DNS error” from IE. I’ve verified via IPCONFIG /all (and the registry) that the correct DNS and WINS servers are listed, and this workstation is the only one on our network with this problem. I have put individual listings in a hosts file, and it still gives me a “bad IP address” when trying to ping names (IP addresses work fine). I have used both static and DHCP IP settings and verified all. I uninstalled IP, removed old registry entries, rebooted and then reinstalled IP and re-service packed it (sp6a) many times. Next I used Etherpeek to do a packet analysis, and noticed that no DNS packets are being sent from the workstation at all. I even tried a different PCMCIA card. (Sorry for the repost, got a little hasty with the replies).

Could it be the Network Icon, Adapter Setting, property set to Thinnet rather than PCMCIA?

No chance – all other networking components work fine.

If you are using both WINS and DNS, and neither one is working, this is a real puzzler! Have you tried removing one or the other, and see if the one that’s left works? For example, try removing the DNS entries from the workstation leaving just theWINS server addresses and see if this resolves local host names. Also, when you say you can ping IP addresses but not names, can you ping the DNS server’s IP address, and/or the WINS server’s IP? It really sounds like there’s something that’s causing that workstation not to be able to communicate at all with these servers. The thing is, if you get a “bad IP address” response from DNS, this usually means just what it says – that the DNS entry is pointing to the wrong (or an invalid) IP address. I’ll keep thinking on this one. You might want to give in and call Microsoft at this point – I know it costs beaucoup bucks, but it might save you bb’s in troubleshooting time, too. In the mean time, good luck!

i take it you can ping locally? it may be your PCMCIA drivers. What type of laptop is it? Can you ping the DNS server? That would then rule weather you have DNS resolution problems. Do you have DNS enabled? and is the hostname OK? What happens if you manually add the hostname into the DNS records?

I can only ping ip addresses whether local or internet. We have DNS, hostname is fine, can ping problem workstation by name from other workstations. Sorry!

Hello there. When you mentioned that you changed your PCMCIA card…do you mean changing the slot too? I have the same problem with the Toshiba notebook and I even cahnged the card..but I did not put the new card to the other slot. Please try putting in a new nic card into a different PCMCIA slot and reconfigure your network. Another idea..please check your lan cables too?

Good luck

Thanks, but I already tried all of that.

Your computer is looking in the wrong place for the DNS (and possibly the WINS) server. Either your default gateway or your subnet mask is wrong. Also check to see if your IP address is on the subnet you are currently located on.

Hope this helps,

Been through that stuff a week ago…

Besides checking your subnet mask and gateway, you may want to check you DNS settings (sounds stupid to remark, i know). Fill in the hostname and the domainsiffix, sometimes this makes the difference. Furthermore you can check if TCP/IP is the primary bound protocol (no netbui or IPX above it at the bindings)

I’ve tried all combinations of configurations with no luck. We don’t use any other protocol than IP. Thanks though.
