Hi, We have a simple AD. Just one domain and nothing extra (no childs etc).
BUT what we do have is a domain spread across different IP addressing systems and DC's behind Firewalls that have to do NAT. One of our sites uses private IP numbers (site A) and another uses public (site B).. What this in effect means is that A DC will get one address from the site it is in say 10.1.5.1 and everything on that site will see it as that (including itself) and from site B it is say 115.151.9.10 so the DC's on that site see it as that. The first and main DC is in site A We have always in the past managed to get round the island issues by have a primary DNS and Secondarys on each site and pointing servers to these making the sure the DC DO NOT point to themselves. BUT it's a little hit and miss. We now have a further site which is a subsite of site B and uses private addresses (so thats private within and site of public attaching to a site of private). The New DC in the New site is currently on its own (and is its own DNS) and was okay .. for about a week and now is an island. I can't point it at any other DNS as It's number will be wrong (due to NAT) in the other sites ones (and they have dynamic updates on). Will adding a second DnS into the site and using that instead fix it ? or does anyone have some sage advice (apart from don't do what you are doing ... it's not an option). I can't point all my DC's at one DNS and can't use AD dns because of the different IP numbers for the servers depending on where you look at them from. Help.
