Migrate and/or replace old cert server?

I am using AD cert services for RADIUS authentication of wireless client devices and users.

Yeah, that's more of where I think of it being used.

First let me say that I know nothing about certificate services, IIS or SQL (all three of which are currently configured and running on this server).
Why are those together? That's not generally a best practice. I realize that Windows licensing causes some decisions that would otherwise be poor, but this seems an odd combination.
I'm betting it's mainly because the company didn't want to buy 2-3 physical servers. If they would have gone virtualized back then, they might be on different OSEs.

@Shuey said in Migrate and/or replace old cert server?:
From what I understand (which is not much, lol), this server is what every workstation and user account on the domain gets its certificate from.
Which certificates would those be?
Where does this understanding come from? Is that documented by your predecessor somewhere?

Is it common for every business/company that has a domain network to have a cert server for issuing/updating all of the AD account certificates?
Maybe I've lost my mind but... what is an "AD Account Certificate"?
You can integrate AD with certificate services so that the workstations use the certs for communication. I've never seen it done.
The only time I have used certificate services is to generate certificates for securing communication between Wireless APs and company owned devices.
While I haven't seen it, I've read about it in NPS (Network Policy Server setups). The machine comes on the network, checks in with the NPS, and the NPS determines what VLAN it should be on, etc, etc.

I wonder if you just shut it off if anything bad happens.
It doesn't really work like that. Since he has only one server and it's not a service to be shutdown, you can't really do that.
There is no service associated with it? How does that work?
When did he say there was no service associated with it?

This makes more sense now! They USED to do radius authentication, as well as wireless authentication via the cert server. Since we no longer use either, it sounds like I might be safe to completely skip this project all together, and move on to the SharePoint project. What do you guys think?

Right.... so assuming one bad decision leading to another.

Very likely. Honestly, kill the service on a Friday night, test some things on Sunday. See if on Monday morning anyone notices anything. Give it a month or two before you remove it completely. Just leave it shut down to see if anything breaks.

Now you need to see what certs you're using for SharePoint. If you're using a public cert, then it sounds like you're right.
what did you replace your Wireless RADIUS setup with?

@Dashrender said in Migrate and/or replace old cert server?:

I think that was from me saying there wasn't a service that you could shutdown. I meant under windows services, there isn't one for certificate services that you can stop.

yes. I've done it that way.

I know you've been using virtualization since the day VMWare rolled out their first internal only beta (yes I'm kidding), but I don't feel that the SMB really started using virtualization until 2010 or later. It's likely whoever setup this server was unfamiliar with virtualization and they were working with what they knew.
I guess you could say that the bad decision was that the business had a one man/very small IT internal staff. If they had a good MSP or consulting business partner, they might have have gone another route.

Yep, at least that's my understanding. It uses certs to assert who the machines are. Anyone without a cert is automatically assumed a guest and put on the appropriate network.

Yeah, Ive been using it since the 1980s.

what did you replace your Wireless RADIUS setup with?
We use local logins on all the of the equipment that used to authenticate via radius (switches mostly), and as far as wireless goes, we don't allow any workstations to connect to our domain via wireless; they are only allowed to connect to a public SSID/subnet.

@Dashrender said in Migrate and/or replace old cert server?:

That's mostly true. But pointing out that the SMB pool often does things poorly doesn't change anything. It remains as bad of a decision whether it is a one off or a commonality. The idea that "the SMB pool isn't doing a good job in general so we can excuse a specific one doing a bad job" is a bad one. It's not good logic. The average SMB will fail and go out of business in the first two years... that standard of what "most" do means we should automatically know to avoid that thinking.

When I look at the Certification Authority console on the server, and I look at "issued certificates", I see line items like this:
"Request ID", "Requester Name", "Certificate Template", "Certificate Effective Date", "Certificate Expiration Date", etc, and I see a bunch of workstations listed.I wonder if you just shut it off if anything bad happens.
We had a cert server running here when I started. Couldn't figure out what is was issuing certs for. I shut it down and... nothing happened.
OP might want to check event logs on cert server and workstations as they boot up and log in to the network. Could be radius authentication for the workstations.
