How to configure DNS on Multiple DCs (AD integrated)
Posted on 2004-08-21
We have 15 DCs in total and we intend to make all DNS and GC.
6 are in a central location on a 100gig LAN connection. We have made 6 seperate sites to divert client login to specific DCs.
6 are on remote sites with 4Mb connectivity to central site.
2 are in data centers with 34Mb connections and serve at least 20 remote small sites.
I have configured my first win2k3 DC + DNS + GC (Currently this has all FSMO roles but this will chaneg as we add the other DCs).
I am about to install and add the other DCs next week.
Q1) When I install the DNS service on the new DCs, How do I configure these? DO I configurte them as secondaries and let AD integration take care of replication? Please put details in your answers including inatll and config stages.
Q2) As these DCs/DNS servers are AD integrated, DO I have to worry about DDNS records being replicated to ALL DCs? I will have 5 dedicated win2k3 DHCP servers that serve 80 VLANs. We use the router Helpers to divert the clients on specific vlans to the specific DHCP servers. The DHCP servers will be configured with specific userid and password to update DDNS records on behalf of the clients. My worry is that the 8500 clients will create a lot of DDNS replication traffic as part of AD integrated replication.
I need this answer urgently. Thanks
