DNS - Adding a new host

Posted on 2008-06-11

Hello all,

I have DNS configured on a Windows 2000 Server/SP4 server.  We also have DNS configured on a Windows 2003 server.  I recently switched DNS servers for our internal network from the Windows 2003 box, to the Windows 2000 box.  Apparently, there are some host records on the 2003 box, which are not on the Windows 2000 box and as a result, certain errors are occuring.

When I go onto the Windows 2003 box, I can right click "abc.com" which is located under "Forward Lookup Zones" and choose "New Host (A)."  However, when I try and perform that same task on the Windows 2000 box, I have no option to create a new host.  Does anybody know why this might occur?  I don't see any option to transfer a host file from one machine to the other, and I am a bit confused.

I am not extremely familiar with DNS and I am thinking this is a simple one.

Thanks for all your help in advance!

Mike

Hi Mike,

What is the Zone Type on the Windows 2000 box? If it won't let you create records it suggests the zone is Secondary.

And, if the zone is AD Integrated, what is the Replication Scope set to for the DNS Zone on the 2003 box?

Chris,

Thanks for your reply.  The answers are as follows:

1.  The zone type on the windows 2000 box is Secondary.  So, from your above comment, it makes sense why I cannot create a new host record.

2.  The replication scope on the Windows 2003 box is set to: "All domain controllers in the active directory domain."  The windows 2000 box does not happen to be a domain controller, which I assume is why all the host records aren't being pushed down to the windows 2000 box.  

3.  One other question:  If the windows 2000 box is not a domain controller, why would it get certain DNS records from the windows 2003 box, and not others?  It does seem like the windows 2000 box has some records, but not all from the 2003 DNS box.

Thanks again for all your help.  I really appreciate it!

Hi Mike,

It should get all of them, if you right click on the zone (on the 2000 box) and select Transfer From Master does it update with the missing records?

Chris,

I went through and tried "Transfer from Master" on the windows 2000 box, but did not get an updated record set.  I did however check the (SOA) on the windows 2000 box, and the "Primary Server" is an old server name that doesn't exist anymore.  I am thinking that I need to point the windows 2000 box, to the correct machine (windows 2003) in order to get a complete record set.  The problem, is the "Primary Server" box is greyed out and I cannot change it.  

Do you think changing the "primary server" to the windows 2003 box would fix my problem?

Thanks again for all your help!

Hey Mike,

That makes sense then :)

You have a couple of choices, either delete the Secondary then set up a new one to Transfer from the 2003 server. You won't lose anything doing that because the zone is Read Only anyway.

Or, stop the DNS Service on the 2000 server, open up the Zone File in Notepad from %SystemRoot%\System32\DNS\domainname.dns. Then fix the SOA and NS Records. After which it should Transfer from Master. You may need to decrement the Serial Number in there to 1, just to ensure it's lower than the Master.

The first method is probably easier though :)

Chris,

That worked perfectly.  I had to go onto the primary server and "allow zone transfers", but once that was done, the windows 2000 box pulled down all the records.  

Thanks so much for your help.
