DNS loading from Active Directory in multiple domains

[sparky0904]

Hi,

i have installed a w2k network using ms 2000 dns, the DNS is set to load from the AD on all servers.

I have a top level domain A and sub domains B.a, C.a, etc.

All my DC in sub domains are set to DNS and Catalog servers to aid logon speed.

The DNS servers in Domain A all have the same increment number in the SOA and all seem to be in sync. Trouble is the DNS servers in sub domains are out of sync with the top level domain A, yet are in sync with each other.

I have created a new user in AD in both domains and they replicate fine. I have also created test file in the netlogon shares and these replicate ok via the FRS.

I thought it might of been the name servers but from reading i understand this oinly comes into affect if you are using Primary and Seconday zones.

I have checked the DNS event logs to no avail, i do get some FRS errors but as i say the FRS seems to work fine.

Has ne1 installed DNS in the same setup as i have just to re-assure me it works.

Regards,

Mark Taylor

all these server are responsible for the same zone?

 

[sparky0904]

Well yes sort of.

I was lead to beleive you could have multiple primary servers using AD which appealed to me.

 

[brontosaurus]

Multiple Primaries? So, these aren't AD integrated?

 

[sparky0904]

Sorry yes, I have 5 dns servers all of the are AD integrated.

3 are in domain A.uk

3 are in domain B.A.uk

They all sync ok with DNS servers in there own domain however i cannot get syncing to go cross domain as it where.

For example from A.uk down to the servers in B.A.uk

Make Sense ?

 

[brontosaurus]

yeah, it makes sense. So, on the downlevel DNS server, in B.A.UK, you see the forward lookup zone for A.UK, with a different SOA serial number? Why not set that zone as a secondary on the downlevel DNS servers, and point them back to the A.UK servers for authority?

 

[sparky0904]

I can do that however....

If you use AD integrated all the reverse lookup zones are automatically transffered as well as any new Reverse lookup zones. Also the name servers tab is automatically updated.

Just means that if i add another server i need to go round updating pages everywhere.

Thanks for help i shall continue my trek through the Jungle that is the MS KBase !!

not sure what you mean by that...why do you think you'd need to any updating manually? You can set Reverse zones as secondaries also...that's the whole point of having a secondary, replication is automatic.

 

[sparky0904]

Yes, but when u create a new one in the a.uk domain you have to manually set all the name servers, scondary serers, etc in the zone to replicate it to other servers.

In the AD integrated create the zone and it is automatically replicated across the DNS structure at that Domain level.

What i will do is replicate all the zones all the servers which are not working correctly in domain B.A.UK

Did you resolve the issue of not being able to do zone transfer across domains using AD integrated?

 

[sparky0904]

No, i have resorted to having the DNS AD replicate in the top level domain and the lower level domains as secondary DNS servers
