Adding 2008 DC to existing 2003 Domain. Do I need to do anything with DNS?

cybershock13045 used Ask the Experts™
I'm going to add a 2008 R2 Domain Controller to an existing 2003 Domain and would like to know if there is anything I would have to do with DNS?

I've read through the steps to adding the 2008 DC to the 2003 Domain (adprep, dcpromo, etc) and I can't find anything that would indicate I would have to make any changes to DNS, but it was brought to my attention in the past that you had to add specific entries into DNS for the DC to take effect.

Thank you in advance!

No changes in DNS, during dcpromo of the 2008 box just make sure to install DNS (checkbox on the same screen as global catalog).  Then the DNS information will get replicated to the box.

Make sure clients are using the new box for DNS (static and DHCP)

I would have to agree with Mike no changes in DNS. DNS data will be replicated with your AD if you are using AD integrated zones.

Nothing is required on DNS side.


Very good, glad there isn't much I have to do with DNS. Thank you!
