>From the nslookup output, you clearly do not have your reverse lookup setup correctly. This is OK, if you don't mind seeing the "errors" you reported in nslookup. So, I would say, don't focus on this as the "CAUSE" of the REAL problem.
The "DNS settings" file you posted is not helpful. You will need to post THE DNS settings on the TCP/IP properties of the server you are trying to promote. From the "DNS Settings" you posted, I can see that there is no record for 172.16.0.20, which is one of the DNS servers your promo-candidate is looking for. Also, I don't see any other address for any other server besides 172.16.0.30. The promo-candidate is not even registered. Another thing to look at is lmhosts config on the promo-candidate. Make sure you look in the TCP/IP -> WINS properties and uncheck the "use lmhosts" options. All in all, I would say you are looking at misconfigured DNS issue here.

I was able to join S1 as a member server to fanmats domain. This is never been an issue, only when I try to promote it. Running Nslookup command it clearly states that it can't see the domain controller, any suggestions? I also disable Netbios over TCP/IP. Also, I ran both DCDaig and NLTest and once it finished it went away. Where does it store the results? One more thing: I'm placing the server's on a network that already has a Windows 2000 domain in place. "Millmats.com" Because new building isn't ready yet and the going live date is July 1. To isolate problem, I took it off the network and now just have them connected between a hub.

If you install the support tools from the Server CD on the first DC, when you run DCDiag and NLTest, is everything (well nearly so - one or two things will fail..) successful? As to network - are both of these DCs on the same network or separated onto different subnets? And, you state that you can ping by name..... Is this machine name, or FQDN - and for which machine from where? Using nslookup from the second DC, can you resolve and lookup, say the _msdcs.<domain name> zone? The problem is clearly DNS related - either it's not resolving correctly or it's not being reached. If the zones are not registered on the DNS server, stop then start the NETLOGON service. for the first DC. Also, how do your event logs look on the first DC? DS, DNS, NTFRS? Everything look good? Anything out of the ordinary in the System or App logs? Let us know what you find out!
