DNS problems

By adunbar ·
DNS is running on NT 4.0 Server

Scenario:

New Domain: JaneDoe.com (registered domain name)
PDC: Windows 2000 Adv. Server/Windows 2000 Exchange Server

Steps:

1. I setup the DNS for the new domain I made it secondary to our internal DNS server.
1a. The zone transfers seem to work fine, but when I tried to do a NSLOOKUP on the server it returned the error message: Can't find the server name for address 111.111.0.11.

2. I went to a workstation on our current domain and did a NSLOOKUP and it gave me the IP address of our ISP.

3. I realized that our DNS servers are listing our ISP's DNS servers for both primary and secondary DNS.

4. I switched the primary to reflect our dns server ipaddress and once again I got the following message: Can't find the server name for address 111.111.0.11.

Any help would be greatly appreciated!

Make sure you have the localhost and the reverse localhost domains defined.

In Zone 127.in-addr.arpa
make sure you have at least the following records/hosts with NS and SOA for type:-

127.in-addr.arpa NS ns.yourdomain.com
127.in-addr.arpa SOA ns.yourdomain.com

and within this zone make sure you have an entry for domain 0 which contains this record/host with PTR as the type:-
127.0.0.1 PTR localhost.

PDC only emulated in win2000, no such thing as a TRUE PDC anymore. Now you have a problem with Win2K, is it in Native mode, running AD?

THis is confusing: You have at least now 3 DNS servers, 1 at the ISP, 1 on NT4.0, and now 1 on Win2000 server. Are you sure this is ADV Server, as ADV Server is much more expensive and is developed for multiple, clustered database servers, and I didn't think ADV Server was out yet.

Facts: You need a Win2000 DNS server, to use for your Win2000 systems, starting with the server. SOunds like you may have this already. Win2K must point to this server for resolution and AUTOMATIC updates. Do not do any DNS replication (or maybe you can setup a cache-only replication), use the ISP's DNS as a secondary server. Get rid of the NT4 DNS and have the clients use the ISP's DNS as primary, unless you're using AD clients, then you'll need to point to the Win2000 DNS first. Win2000 DNS is a vital component of Win2000 server and Active Directory. If this is a vital network, I would seek professional help, unless your are 100% confident in your W2K knowledge!

Sorry just realized I was talking about Windows 2000 Data Center Server, not Advanced Server....Ignore my comments about Adv. Server.

If it is unable to find the name for the IP address, I suspect that you do not have the reverse data pointers configured. There should be a PTR record for each A record in the DNS. This allows for IP to host lookups which is reverse of the host to IP lookups. Even though the nslookup says it can not find the server name, you still can do host name lookups.
