DNS Replication

I have 3 domains, 1 parent domain & 2 child domains, every domain has its own DNS Server & since these domains are in one forest so the two child DNS zones come under the Parent Zone, the problems I have been having lately is that if there are any new changes like addition of PCs to the domain their entries are added to the local DNS Server of this domain but is not replicated or transferred to the DNS Servers of the other two domains, this event is OK if it is limited only to normal PCs but the problem happens when any new server is involved; in this case the servers from the other domains cannot resolve the name of the new server & hence cannot communicate to it.

Now in the DNS Server settings of every DNS Server for every domain, in the properties of the domain under the Name Servers Tab, I can see all the DNS Servers for the forest in the list, & on the Zone Transfer Tab I have selected the option that Zone Transfers should be sent to all the Servers mentioned in the Name Servers Tab.

I hope that the steps that I have mentioned are correct if yes then my question is why any entries are not being replicated to the other DNS servers & if the steps are wrong please guide me for the right procedure.

THANKS....

Are you using AD Integrated DNS?

Yes sir...

- there goes that theory then!
Depending on your network, there is always going to be come DNS latency as replication is not instananeous. There is some info at http://technet2.microsoft.com/WindowsServer/en/library/4f504103-1a16-41e1-853a-c68b77bf3f7e1033.mspx?mfr=true that may be of help.

Zone Transfers relates to replication from Primary to Secondary zones. It is not the right place to be setting AD-Integrated replication. You need to look at the setting for Replication that is shown on the General tab in the zone's properties. It is the third item on that tab (just below where it says Type: Active Directory-Integrated). Click the Change button. If you change it to the first setting "All DNS servers in the AD forest" then it should replicate to your child domains.

Thanks that was very helpful, I have checked this setting in every DNS Server, the settings that I see are that the replication scope for Zone in the DNS Server in the Parent Domain is set to be replicated to all DNS Servers in the forest, but on I am unable to apply the same setting on the DNS Servers of the 2 child domains. The error I receive is;

"The Name Limit for the local computer network adapter card was exceeded"

ANY NOTES ??

I can't think of an obvious explanation, but you could take a look through this article to see if it helps:

I think the link I was looking for was;
http://support.microsoft.com/kb/887418
but the steps mentioned here say that I have to delete the Zone on the server that is having this problem, but how come... I dont understand; these zones were auto created by the Active Directory Wizard when we created the child domains, so how can I delete them. And also after deleting what am I supposed to do.. I mean should add this zone again to this server ... & should it be Primary Active Directory Integrated or Secondary.
