Hi guys.

I'm hoping you can throw some input into the below for me.

I am setting up a DR site.

Server 1 : 10.39.2.1
DR Site (Off site) : 10.9.2.1

So i have tested the DR itself and everything is working. But with these being on a different subnet and location (using veeams RE-IP) when i ping the DNS name its still trying to ping 10.39.2.1 and not the new 10.9.2.1.

Do i just add another DNS entry on both domain controllers? so,

server 1 Host A 10.39.2.1
server 1 Host A 10.9.2.1

Then it once the DR server boots up and hits the DC it will auto swap over? Or am i missing something. Any help would be great full. I can do this manually on fail over but i'm trying to get out of doing it manually and getting it automated.

Thanks.
 
Changed the order that the nic uses to lookup DNS entries?

Edit:

Easy enough to write a simple powerchell or .bat to see if Primary site is pingable, if not, test ping to DR site, if DR comes back swap order of DNS
 
Hi there thanks for your reply.

Thats my point, i don't want to change DNS manually.

I want DR to work without user intervention.
 
Assuming your using vmware or hyper-v with some form of san replication, when the VM boots up just get it to run a script to test connection to the DNS server as mentioned above. if no ping to primary DNS, then get it to change DNS without manual intervention. It's how we do things at my place.
