DNS Replication not working


We have 3 DNS servers. Two of them are Windows 2008 and one of thm is a Windows 2003.

When changes are made on any of the servers (such as adding zones or changing IP address of items already in the forward lookup zone), the changes are not being replicated to the other two servers.

What needs to be done to get them to replicate to each other automatically?
Is there a way to force their replication on demand?

First question is have you run any diagnostic tools against your DNS or AD health?  Also, have you checked your server's event logs to see if there are any errors related to DNS replication?
Darius GhassemCommented:
Are you running AD integrated zones?

Go to the properties of the zone to make sure you have zone replication enabled for the other DNS servers to receive the Domain Transfers

I am not familiar of how to run any tools against DNS or AD health.  Please elaborate.

I checked the DNS event log. On one of the DNS servers, the DNS log is blank. On the second server, I do not see any warnings or erros. On the third server, I see this warning repeating.

The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed. The DNS server service cannot start until the initial synchronization is complete because critical DNS data might not yet be replicated onto this domain controller. If events in the AD DS event log indicate that there is a problem with DNS name resolution, consider adding the IP address of another DNS server for this domain to the DNS server list in the Internet Protocol properties of this computer. This event will be logged every two minutes until AD DS has signaled that the initial synchronization has successfully completed.

It seems that my boss has created new Forward Lookup Zones and did not select "Store the zone in Active Directory".

Once we checked that box in the properties of that zone, it replicated to the other servers.

Thank you for your help.

Seems that replication needs to be selected as well as the zone needs to be stored in active directory.
