We just installed a new server with Windows 2000 server and removed our old Small Business Server NT 4.0 server. We have mostly Win 98 clients, but we also have 2 Win 2000 Professional clients. We have a DNS and a DHCP server set up. All the clients are getting addresses and can use network file and print resources. The Win 98 clients can surf the internet just fine. However, the 2 Win 2000 clients cannot. I can enter external addresses explicitly and it will work just fine on these machines, but they will not resolve domain names. That is the only thing they won't do. How come my Win 98 clients are resolving just fine, and my Win 2000 clients will not? I know it is a DNS issue, but I can't seem to track it down.

Open up a command prompt on the 2k machines and type in ipconfig /all

What are their dns servers pointing to? Is it correct.

Next, type in nslookup

Try to resolve a name such as www.yahoo.com

Does it resolve. If not, whatwas the default server it went to?

Can it connect to that default server or did it say timed out.

You were on the right track. To speed up the process I decided to use one of my free incidents with Microsoft. Found out the DNS server was configured incorrectly. The 98 clients were using the router to resolve DNS. The 2000 clients were using the server which was configured incorrectly. The DNS entries that should have been in the forwarding section were in the DNS search list and in the DHCP scope. Experience with Microsoft was great this time. Fixed the problem in about 30 min. Thanks.

to add to Lords excellent answer,
when in the dos prompt do a ipconfig /?. look at all the things you can do. Try the flusdns after trying Lord's suggestions. the nslookup is key. if it doesnt return your server as the address which qulifies the name then it is being passed up the line, either because it was set that way or there is a problem with your dns config.

Is the DHCP and DNS server a w2k server? Can you see the machines registered in the DNS and DHCP MMC snap-in? From the DNS box, can you do a tracert to the 2k machines?

The ipconfig responses work great if your running MS's DNS, but if you running BIND lower than 8.0, your gonna have issues. Dynamic DNS is the key with w2k.
