RE: [ActiveDir] DNS Server Using its own IP as a Primary DNS

[Roger Seielstad]

Anyway, why force a DC to go elsewhere for its DNS info – just make it query itself and make DNS AD-integrated.   Because replication will break? AD replication relies on, among other things, correct DNS entries to find the other DCs, and if they're missing, you're screwed. If the DC only references itself with AD integrated DNS, you risk what's called a DNS island, where the server only knows about itself.   The other option, which might be the way to go, is to set the Sydney box to be a standard secondary of the DNS zones in Singapore, at which point it CAN use itself for DNS, and it will forward registration requests to its primary server(s).   Keep in mind that DNS is really, really light weight network traffic, and when combined with its native caching abilities, DNS across the WAN is hardly an issue.   Roger -------------------------------------------------------------- Roger D.

I am going to configure a new DC/DNS/GC for Sydney. Singapore has 2 domain controllers running DNS. The new system in Sydney uses the DC's in Singapore as it's primary/secondary DNS. After I run DCPROMO and configure DNS on the Sydney box, should I continue pointing to Singapore, or should I have the system point to it's own IP as primary DNS. I have heard two schools of thought on this issue, and just wanted to get an opinion. Thanks, -Jbl
