adding 2nd Domain Controller best practice...

Hi All,
Currently have Primary DC server 2012 Standard (AD/DNS/DHCP) - will it be ok to install Server 2012r2 as 2nd DC rather than Server 2012 Standard ?

Yes, that's fine.

Just don't install a DC with a lower version than your domain functional level.

you should be fine as long as functional level isn't lower than the current one.

thanks guys, the IP setup will be as example:
DC1:
server IP: 192.168.1.2
DNS primary:192.168.1.2
DNS Secondary: - shall I leave this blank or add DC2 IP?

DC2:
server IP: 192.168.1.3
DNS primary: 192.168.1.2
DNS Secondary: 192.168.1.3

Hi Jag,

There is no problem with configuring a secondary DNS on both DC's, if the service fails it always good to have a secondary...

Cheers
