Exchange 2016 Install Issue
-
Just so I understand the environment.
You had/have
AD server - still have
Exchange 2013 - now gone
Exchange 2016 - now goneIs that right?
Assuming it is, now you're trying to add a new Exchange server back into this environment, on a new server, so you'll end up with
AD server
Exchange serverQuestion - do you still have the old data from Exchange 2013/2016? that you need to put into this new Exchange server?

you mean you were not making this a VM? crazy man, crazy!
Nah man, remember I was waiting on the H730P? I was hoping to get up a bare metal in the meantime, but that didn't work out.
Sure, but even a temp box should still be a VM. No reason to really ever make it bare metal.
If I was building a temp Exchange box, I'd slap whatever hypervisor on that box first - make a VM, install windows Server and then Exchange... no different than the ultimate location where I want to host Exchange. Do it this way makes it cake to move to the new hardware - just shut down the VM, transfer it over, import if needed, start it up and go! no worrying about doing a P2V...

They have identical PERC Adapters, lol.

that doesn't really matter - it could have been a desktop for the temp machine - assuming it had enough storage for your needs
this is because you're migrating the VM, which is mostly if not entirely, hardware agnostic... -

I don't. We're considering it a complete loss. Silver lining is we'll get the funding to protect ourselves now, and the opportunity to build everything into VM's.

Is there a reason you are returning to onsite Exchange instead of moving to O365 or some other hosted solution?

Money.

As in you already have the Exchange licenses, so it's mostly a non cash setup situation?
-
How many users do you have? how many workstations? How many file shares - are permissions used a lot in those file shares?
perhaps, it would be worthwhile to start your AD all over again?

Nail on the head.

I'm gonna power through this build first and see how it goes.

So why not setup a fully new AD domain and reinstall Exchange there then? It would be the best course of action as it will be clean.

@dbeato We may have to, but like I said I'm going to power through this build first, and we'll see how it goes.

Do it side by side. Setup another AD in another Server and work through it. I bet the new one will go much faster.
-
@dbeato My plan is to just roll back the snapshot of the AD we have now to when we first built it pre-Exchange. Giving me a blank canvas if it comes to that.

This is a horrible idea. Rolling back AD is almost never a good idea.

@JaredBusch please elaborate.

OMG - THIS, one million times this!

AD is extremely time sensitive. By default, a domain joined PC who's time is off more than 5 mins from the AD server, can not authenticate because the server will think it's being attacked.
Computers also generate their own passwords for connectivity to AD - and they update these passwords completely autonomously. So any machine that has updated to a new password since your snapshot, would no longer work on the domain.
There is a process for restoring an old version of AD into a network - but it is rather complex (and something I've never done or seen done).

I literally just rolled back my AD/DC a week ago. The process was very smooth. You just change the time and Boot/re-add every machine to the domain. The latter being the most timely, but it’s really easy.
That’s my experience at least.
