DNS resolving issues

We have just added a new child domain to our network and installed a win2000
DC which is also acting as a router (additional NIC added) between the
domains, We are running DNS with AD and we can resolve nslookup querrys from
this child domain for the main domain but can not resolve anything from the
main domain for the child domains.
'none-existing domain'

Has any one any idea why this is happening and How we can resolve it.

On Win2k servers, you need to create secondary DNS zones on your main domain
controller DNS for the child domain.
 
HI..thanks for the response, it's been a while since I setup DNS for a child
domain. I did try to add a second DNS on th emain domain but the child domain
dns server is not shown when you try to add the file (doent see the child
domian server).

I thought that using AD-intergrated and naming these as servers would have
worked?

Hi..managed to get this by entering fQDN so added secondary zone, in this
case do I need to do the same for each dns server on the main domain (3 in
total) or would just the one work fine?

ALso do I need to add a any secondary zones in the child domain dns server?

I have notice another thing the resolution for the main domain servers seems
to be using wins as it resolves netbios but not ip any sugestions whats wrong

When you configure a child domain you either create a sub domain or delegate
the sub domain. Either way, you should then have the NS records for the
child domain. However, AD-Integrated zones are domain specific -they are
part of the domain partition
(CN=dnsZone,CN=MicrosoftDNS,CN=System,DC=domain-name,DC=com), and will
therefore not be replicated to anything outside of the domain. The only way
to do this would be to create a secondary zone that pulls the AD-Integrated
info.

The way I tend to do this is as follows:

- Dcpromo the server when pointing to the soon to be parent DC. This then
creates the appropriate sub domain in the DNS zone. With this created,
delegate this zone to the child DC.
- Once the delegation has taken place, change the zone to AD-Integrated, and
allow zone transfers to the parent domain's DNS servers. On the parent
servers, create a secondary zone for this zone.

When using AD-I zones, the zone transfers tab is only used for DNS servers
that are not part of the same domain. Also, multiple domains will require
secondary copies of the other domain's zone files, for cross domain name
resolution and the trusts to work.

Hope this helps,
