At home I run the following network:

All the client PCs use WinXP and the server has Win2k3.

On the server I installed DNS Server, but now have the following problem when doing

nslookup on either the client computers or the server itself:

C:\Documents and Settings\Administrator>nslookup www.starwars.com
*** Can't find server name for address 192.168.0.1: Non-existent domain
*** Default servers are not available
Server: UnKnown
Address: 192.168.0.1

Non-authoritative answer:
Name: www.starwars.com
Address: 206.13.40.51

mine does the same thing however I am not running into any problems. Are you running into any dns problems?

No, everything works as it should.

What should I put into these two fields:

FORWARD LOOKUP ZONE

REVERSE LOOKUP ZONE"

What you should be doing is forwarding the DNS on your server to your ISP's DNS server(s). That way the queries within your network will be forwarded to the internet.

I put ISP's DNS into FORWARD LOOKUP ZONE.

But what should I put into REVERSE LOOKUP ZONE?

LONG POST AHEAD -

You didn't mention if this was on a workgroup or a domain, but this reply is more for a domain. On the server - Primary DNS should be the server's IP address. There should NOT be any ISP's DNS on the secondary. Like the other poster said, if you go into your fowarders tab under the DNS MMC, you can create your foward and reverse look up zones. The reverse lookup zone, is usually in the format of "x.0.168.192" In theory, that's how a lot of mail servers decide whether or not to bounce or receive mail. If it can't do a reverse look up (spammers commonly have this problem) then it gets a rejected mail from the reciepient.

The client should have their server's IP on the primary DNS so when you do an Nslookup, It should now say:

DEFAULT SERVER: 192.168.0.X

SERVER.DOMAIN.COM(LOCAL)

sorry for the long reply.
