When i execute an nslookup command, i get a time-out error. And sometimes:
Can't find server for address : Non-existant domain
Every windows2000 client is registered in the dns.
I think the DNS is misconfigured. What can i check?

you can try using the dns diagnostic tools. Just open up dns mmc. Then right click on you dns server name to get the properties. Then look for Monitoring tabs bar. Over there you should be able to try 2 diagnostic method. If I remember correctly, one is for forward lookup and another is for recursion. Usually the one that will fail is the recursion test. Anyway, if you see fails, that means something is wrong with your dns setup. The first place i would look for is the forwarding issue. I suspect the reason is resolving internet domain names. You need to forward the resolving of external domain names to your ISP. Try adding you ISP's dns.
