question about setting up a new domain controller

@dave247 said in question about setting up a new domain controller:
As I explained in the OP, Exchange 2010 SP3 will not work with a 2016 DC.
That can't be right. What's the documentation on that?

@dave247 said in question about setting up a new domain controller:
The main thing I'm wondering about is if I can simply set up the new 2012 R2 server, promote it to domain controller, and then one by one point my servers and all the other statically mapped systems to it, without experiencing any disruptions.
You can have all three, or more, running at once, you disruptions. The only thing that gets repointed, static or dynamic, is the DNS settings, not the AD ones. DNS handles AD transparently.
I don't understand..

So it does say it there, how is this possible? How can 2016 be working properly yet break something like this?

What is driving you to do a fresh install of an old OS?
Exchange 2010 SP3 he said.
How does that affect the DC, though? That affects the Exchange server.
Yeah, if Exchange won't work, then I don't want to use 2016 for now.

Which begs the question.... how is 2016 doing 2012 or earlier domain levels, if it isn't fully compatible with them? How and why did MS break that in that way. That's very concerning.

Yes, that is what I was going by. Sorry I didn't post it. I didn't have time to dig up the link..
So am I correct that having a 2016 DC with Exchange 2010 SP3 (AND NO 2008 R2 domain controllers) will not work? I want to get away from 2008 R2, ya dig?

You can have all three, or more, running at once, you disruptions. The only thing that gets repointed, static or dynamic, is the DNS settings, not the AD ones. DNS handles AD transparently.
I don't understand..
AD DCs run in clusters. You can have as many as you like, they are one single pool. So you can add as many as you want, and they all get used, live.
You never point to AD. There is no setting for that on Windows. The clients request AD information from DNS, DNS points them to the AD DC that is best for them at the time (or just round robin.)

I don't know. I was also confuxored as hell but hey I have to work with it.

According to the chart, no it won't work. It's just insane that that could be the case. It means MS failed to maintain application compatibility across AD, even at matching compatibility levels.
It's a pretty big fail on MS' part and shows very much that AD is not as robust as people like to think.

And they provide no explanation for something that I feel demands rather a bit of it. They just ignore the fact that they have this big break.

Just be glad YOU haven't had to deal with Exchange's silly requirements lately!

ok. Let me explain my reasoning a bit better since I am clearly not doing a good job.
DC1: 10.0.0.9
DC2: 10.0.0.10
New DC: 10.0.0.11Right now, ALL my static mapped servers, printers and appliances point to 10.0.0.9 as primary DNS and 10.0.0.10 as secondary. If I am introducing a new DC that will eventually REPLACE DC1, then I need to REPLACE all entries that look at 10.0.0.9. Does that make sense? That's what I'm worried about, that I don't miss anything or mess something up during the span of time that I am making the change.

Hey, Microsoft support disagrees with the matrix and says that it DOES work.

Exchange 2013 was the big change, that works with everything except Server 2003.
Exchange 2010 is the old style Exchange, so it makes perfect sense it wouldn't work with Server 2016.

It doesn't make any sense at all as the AD is supposed to be absolutely identical regardless of the OS version it is running on. If the OS version changes anything as far as support, AD isn't stable and their versioning is broken.

Yeah, I can have Exchange 2016 with 2008 R2 domain controllers, but I can NOT have 2016 domain controllers with a Exchange 2010 SP3 server
-
I see, having Server 2016 is fine, however, Domain functional level can't be.
