Join Ed Liberman for an in-depth discussion in this video Post-installation configuration, part of CompTIA Server+ (SK0-004) Cert Prep: 1 Server Administration.
- [Instructor] When it comes to installing a server operating system it's really kind of a two-step process. Step one is the actual installation itself. The actual deploying of the operating system on to the computer. But after that, we need to do what's called post-installation configuration. Which is really where we just go through and make sure that the machine is configured appropriately for the type of use that we want out of it. So what I wanna do here is I wanna jump back into a virtual machine here called Windows Server where I just installed Windows Server 2016 in the installation video.
So let's pop over there. So the first thing that we see when we log in to a Windows Server is we see this thing called the server manager. Now something I wanna point out right away that I see on the screen and you see on the screen that tends to be alarming is these red boxes. We see these red boxes, red always seems to be some form of alert. So I wanna talk to you about what this is in the world of Windows Server 2016.
You'll see that I have this number five in the red box next to services. And when I click on it, what you'll see here is that there are five services that are currently stopped. Now the start-up type is set to automatic, but with a delayed start. Now there's a couple of reasons that these may be stopped. Number one, when it says delayed start, that means that, just what it sounds like, it's not going to necessarily start right away when you first boot up the machine.
Now there's two things that can cause these services to launch. One is they may just be waiting for other services to start first, and then they'll go ahead and start afterwards. So the service may be dependent on another service. And that means that these'll go away automatically. But another reason maybe that the delayed start is that the service will only start if we are performing an action that calls for this service.
Now I happen to know that of these five services, even while I'm talking we may see them magically just disappear, it's something that will happen automatically. And in fact, four of these are gonna automatically disappear and there's only one and it's this one right in the middle, the downloaded maps manager, which will never start, other than if we perform an action that calls for it. Now we have two options when it comes to a service like this. We can either just leave it where it is, and what that means is, and I'm just gonna go ahead and click okay to come back to our server manager here.
It means that I'm always gonna see a red box and I'll just have to know that if I see a one in the services box here, that that's okay. Because I have the one service that I know is not gonna automatically start. But if I research the service and it turns out that I don't need it, then I can disable it. And the way we can do this is by going into the services utility. So I'm gonna come to the lower left hand corner and click on the start button here. And type in the word service. I'll just start typing it in and you'll see there's an app here called services.
So I will click on that app. Here in the services app I will scroll down a little bit. Went a little too far, here we go. The downloaded maps manager. I'm gonna double-click on it. And you'll see here it has a start-up type of automatic delayed start. I'm going to drop that box down, and I'm gonna change it to disabled. And click okay. And you'll see here that it is now disabled. I will close out of this utility, come back here to the server manager, and you'll see here that I still have this five in the red box.
Well, nothing's going to change until it hits a refresh cycle. And it's not automatic. If I wanna force a refresh, up near the top here, there is a refresh button. So I'm gonna click on that, and let's see what happens. Perfect. All the services have started. Now I only did the one service, but the other four started automatically. But this is how I can get to a nice, pretty, non-alarming, you know, no red boxes screen. But that's just one little quirk of Windows Server 2016.
The main thing that I wanna show you when it comes to post-installation configuration, is right here. Where it's, up at the top, where it says configure this local server. I'm gonna click on that. And this is really the primary place where we go through this post-installation configuration. The first thing, up at the top it says computer name. And you'll see here it's like this random name that's been assigned. So I'm going to click on it and then click change. And here is where I can change the computer name. So let's say I wanna call this windows server.
And I will click okay and when I do that it's gonna tell me that in order to change the name, you have to restart. So I will click okay. And I will close this window and tell it to go ahead and restart now. And you see the windows jumping around a little bit because I'm in a virtual machine. But it's going to go ahead and just reboot right back into the operating system. And here I can go ahead and type in my password for the local administrator account.
And once again, it's going to launch straight into the server manager, right where we were before. Now when I do this, because I just rebooted the machine, guess what happens. I have these red boxes again and there's those four other services that are on delayed start. But because we know that those four services are always on a delayed start we don't panic when we see these boxes right after a reboot. So I'm gonna ignore this and just go back to configuring the local server. And you'll see that the computer name is now windows server. I could also go ahead and click on the work group if I wanna change this to joining a domain.
You'll see it actually takes me to the same window I was in before from when I changed the computer name. Click on change. But instead of dealing with the top part we're gonna deal with the bottom part where I could make it the member of a domain. Now I can't do it here because this is the only computer I have running on my network here. I could maybe make this computer a domain controller to start a domain. But there's nothing for me to join right now, but that is where I would join the domain if I wanted to do that, if I was set up in an environment to do that. So let me cancel out of here.
Let's talk about a few of these other settings. We could configure firewall settings, and this is Windows firewall, so these are individual to the computer. Remote management is turned on, we could turn it off if we wanted. Remote desktop is turned off, we could turn it on if we want to. NIC teaming is if we had multiple network cards, we could have them work together to increase bandwidth. And then here, this is the next significant item, which is ethernet. Where here I have the IP version four address is assigned by DHTP automatically and IP version six is enabled.
And if I click on it, takes me into my network connections, I have my ethernet connection where I can right click and go to properties. And a couple things, based upon what we just saw. If I wanted to disable IP version six, I could just clear the check box. Although I need to tell you, you're never really disabling IP version six. It's still running, you're just disabling that you will see anything related to it. Just an FYI. If I wanted to configure IP version four, don't click on the box but click on the words, which highlights it and then click properties.
Right here you can see I'm obtaining my IP address automatically. If I didn't want to do it automatically, if I wanted to put in a static IP address, I could do that. I could click the button saying use the following IP address and then type in my IP address information. Now I'm not gonna do that, I'm gonna cancel all the way outta here, I'm gonna go ahead and leave this with me getting my IP address from a DHCP server. Because I do happen to have one of those running on the network, so I do have an IP address. And then if I move over to the right column, you'll see here, it says last installed updates.
Never. Windows update, right now it says you will install updates automatically using Windows update. When was the last time you checked for updates: never. I could do that right now, and it's a good idea when you are deploying a server that you do this right away. 'Cause this is how you'll get all the security patches. I'm not gonna do that here because it will take quite a bit of time, so I will do that not while you're watching a video, 'cause that would be quite boring sitting here for what could be an hour waiting for all these patches to update.
But it is something you wanna do. And you do it by just simply clicking on the link and it will take you into the settings where you can tell it to check for updates, and then install those updates. So that is something you are gonna want to do. Additionally, Windows Server comes with Windows Defender, which is currently on. I could turn it off if I wanted to. I could also go through with some feedback and diagnostics. This is just a Microsoft Windows thing, and in fact, I am gonna go ahead and I'm gonna tell it never to ask me for feedback.
Because this is not an actual machine. This is just a test machine that I'm demonstrating on and I don't wanna send any feedback to Microsoft based upon things that we might do that are kind of out of the norm. This is Internet Explorer enhanced security. It's on by default on your servers. I do tend to turn it off on my demonstration machines. On a production machine I would leave it on. On a demonstration machine I turn it off. So that I'm not bothered with the extra security if I need to go out to the internet to show you something.
But this brings up one point that I wanted to show you. And you see how I changed it to off but it still says on. Again, things don't always refresh instantly. So I'm gonna hit the refresh button and now it turns to off. I can set up my time zone. Which I'll leave, I am in the Central time zone, so that's fine. And you'll see here this product is not activated. If I wanted to go ahead and activate this copy of Windows Server I could click on it and then I would have to put in my product key to go ahead and activate.
Which again, I'm not going to do on this particular machine, this is just a demo machine on an evaluation copy. The goal here is to show you the idea of going through and doing all these different post-installation tasks. Now once I have done this, in the world of Windows Server 2016 I would jump back over to my dashboard and I could then go on to, for instance the next step here that says add roles and features. So this is where you determine that this server is going to be something specific.
It's going to be a DHTP server, it's going to be a DNS server, it's going to be a domain controller. So that's something, and I'll go into more detail in another video where I show you how to do that. But you'll see here that it kinda walks you through the different things that you could do to actually configure this server and make it ready for, again, depending on what role you want it to have. But for the most part, that's pretty much it. We have done our post-installation configuration and we are pretty much good to go.
So remember that installation is really a two-step process, you have to install but then you also have to do a little bit of configuration to make sure that the computer is ready to operate in the way you're looking to have it operate for you.
