DC DNS Settings

@Romo said in DC DNS Settings:

So I should not change my DNS servers settings then?

Primary: Second Dns
Secondary: 127.0.0.1

Apparently not.

@scottalanmiller

This is why I asked.

See what I mean?

Can we at ML come up with a best practice?

thwr

Looks like I got the question wrong

Veet

Always pointed it to itself, as the primary ... Also, doesn't Microsoft itself recommend this as a Best Practice ?

BRRABill

So, does it really seem like we're all doing it wrong?

That DC1 should have DC2 listed as its primary DNS server? And DC1 secondary?

@BRRABill I have two DCS,
DC1 has DC2 as primary and itself as secondary. Then for DC2, DC1 is primary and itself secondary.

Seems like that is what is now recommended. Though all the first few posters did not have it set up that way, and that is apparently not the way MS used to recommend.

@BRRABill said in DC DNS Settings:

I do the same, itself as primary.

But it seemed like there were a lot of people on the Internet with the opposite.

Of course, they aren't the geniuses here at ML.

I take it back, my servers were NOT set up like this.

Not that anyone cares. Just wanted to set the record straight.

I have been doing the Primary points to other DNS and secondary to itself for over 5 years, and probably more like 15.

Me, too. Never an issue.

I wish we could have figured out why MS seems to be recommending it.

Adding to this:

I've also always point the primary to 127.0.0.1 and secondary to the secondary controller. If no secondary controller, then a public DNS.

Funny there are so many ways to do this that don't break it.

That don't break it.... right away.

So here is a quesiton. When you first add a secondary DC/DNS, do you go back to the original DC and update the DNS on the NIC? Or do you leave the original pointing only to 127.0.0.1?
