(Complete) How to Configure Certificate Authority (ADCS) Server 2016 (Part 1)

I have a need to generate a certificate for an internal web application which would only be available on the LAN or over a VPN connection. Normally, I would just buy a cert but in this case, I think I need to generate my own because it's not accessible over the public net. I'll then deploy the cert through group policy on the R2 DCs.

Are there any issues with this set up? Nothing really wrong with that plan, it would work, but I would recommend setting up a two tier PKI with an offline root so you can keep using this PKI in the future for other applications without having to worry about rebuilding it because it's not secure enough. If you take a look at this guide, the steps and configuration are going to be the same as doing it in I've set this up in a couple of times and it was basically identical to the R2 process.

There is no requirement that your server be publicly available in order to purchase a signed certificate from a public CA. You do need to use a publicly valid domain. So host. If your internal namespace is compatible with public DNS, just generate a certificate request and send to your favorite certificate authority as usual.

Good point Kevin, I was assuming he didn't want to pay for a third party cert because it was internal only, but if the price of a cert isn't an issue, that's definitely the easiest option. The internal domain is a.

It doesn't seem like that would work since UPN is for the user accounts and not computer names. Not sure what the best route to take is yet. To continue this discussion, please ask a new question.

This topic has been locked by an administrator and is no longer open for commenting. Read these nextIn the first part in this series, I am going to walk you through setting up a simple Certificate Authority on Windows Server for a lab environment. If you want to get rid of those annoying warnings every time you open a web session for vCenter, or ESXi or pretty much any VMware product, you have to have a signed and trusted certificate on the web server.

Without it, you are required to acknowledge the risk of connecting to the site and then clicking to continuing on to that site. Unless you go and do the acceptances before you start the demo, you are stuck getting rid of these warnings which interrupt proceedings. In my lab environment, I setup a Microsoft Certificate Authority to sign certificates for the various tools I am running allowing me to get rid of that warning and have all green URLs in my browser. First things first, you need to have a VM running Windows Server I will not go into the details of setting up a Windows Server here.

Step 1. We need to add the Certificate Authority Role to the server. Step 2. Click Next on the information page. Step 3. Keep role-based or feature-based installation selected and click Next.

Step 4. There should only be one destination server and it should be the one you are working on. Click Next. Step 5. Step 6. You should now have a tick against Active Directory Certificate Services. Step 7. On the select features page, leave it as is and click Next.

Step 8. Step 9. Step In previous articles, you saw how to create a multi-tier PKI deployment. You then saw how to set up certificate templates to simplify certificate request operations. After that, we worked through some examples of requesting certificates. In our final installment, we will cover the common operations of a certification authority.

You will learn how to view current certificates and revoke them. We will also demonstrate manual approval of pending certificate requests. If your certificate server runs on a full GUI installation of Windows Serveryou should already have this tool. If you run the tool from any system other than the certification authority, or if you would like to target a different authority, you can retarget the snap-in. You will see a list of every still-valid certificate issued by the authority.

These column selections matter if you want to export binary data, which I will cover in an upcoming section. You can see the binary form of the certificate or any of its components. Despite the text on the menu, you can get the information in text format. Choose the item to export and the format that you want. If you really want binary data, use that option. It will prompt you to save a file. After you pick the object that you want to see, it will show the requested data in a Notepad window:.

Earlier, I mentioned that you might need to adjust the visible columns in order for some of these choices to function. You have many options for requesting a certificate. You can use the advanced option in the MMC Certificates snap-in to create a custom request, which will generate a request file. You can use the certreq.

Once the CA accepts the request, it immediately issues the certificate. You can manually respond to certificate requests in that branch.

The interface will ask you for a reason code and a timestamp. That allows you to backdate the revocation to a point in time close to a compromise incident, if necessary. You can reverse the revocation of a certificate, provided that you revoked it for the Certificate Hold reason. For ordinary backup purposes, you can backup and restore the owning system like any other Windows Server installation. The restore operation typically involves a normal restore of the Windows Server system.

You will normally only use the wizard in the Certification Authority for migrations. It is essentially the same as the backup wizard. For the most part, CAs maintain themselves, especially if you used an Active Directory-integrated installation.

The preceding instructions should carry you through most other situations. With a system this easy to use and configure, you should make the move into a more secure Windows environment sooner rather than later.

For example, a common type of credential is the X. SetCertificate method. There are three different types of certificate stores that you can examine with the Microsoft Management Console MMC on Windows systems:. The following procedure demonstrates how to examine the stores on your local device to find an appropriate certificate:.

From the Available snap-ins list, choose Certificatesthen select Add. In the Certificates snap-in window, select Computer accountand then select Next. Optionally, you can select My user account for the current user or Service account for a particular service. If you're not an administrator for your device, you can manage certificates only for your user account.

In the Select Computer window, leave Local computer selected, and then select Finish. A list of directories for each type of certificate appears. From each certificate directory, you can view, export, import, and delete its certificates. You can also view, export, import, and delete certificates by using the Certificate Manager tool. Select Run from the Start menu, and then enter certlm. To view your certificates, under Certificates - Local Computer in the left pane, expand the directory for the type of certificate you want to view.

Select Run from the Start menu, and then enter certmgr. To view your certificates, under Certificates - Current User in the left pane, expand the directory for the type of certificate you want to view. Skip to main content. Exit focus mode. There are three different types of certificate stores that you can examine with the Microsoft Management Console MMC on Windows systems: Local computer: The store is local to the device and global to all users on the device. Current user: The store is local to the current user account on the device.

Service account: The store is local to a particular service on the device. View certificates in the MMC snap-in The following procedure demonstrates how to examine the stores on your local device to find an appropriate certificate: Select Run from the Start menu, and then enter mmc.In an earlier article, I showed you how to build a fully-functional two-tier PKI environment. At the end of that piece, I left you with the most basic deployment.

In a second article, I showed you how to set up certificate templates. I will use this article to show you how to perform the most common day-to-day operations: requesting certificates from a Windows Certification Authority.

Fundamentally, the process of requesting and issuing PKI certificates does not depend on any particular vendor technology. It follows this pattern:.

The particulars of these steps vary among implementations. You might have some experience generating CSRs to send to third-party signers. You might also have some experience using web or MMC interfaces. All the real magic happens during the signing process, though. Implementations also vary on that, but they all create essentially the same final product. I want you to focus on the issuance portion. You do not need to know in-depth details unless you intend to become a security expert.

However, you do need to understand that certificate issuance follows a process. Sometimes, an issuer might automate that process. You may have encountered one while signing up for a commercial web certificate. At the most extreme, one commercial issuer used to require face-to-face contact before issuing a certificate. Regardless of the degree, every authority defines and follows a process that determines whether or not it will issue. In your own environment, you can utilize varying levels of automation.

More automation means more convenience, but also greater chances for abuse. Less automation requires greater user and administrative effort but might increase security. I lean toward more automation, myself, but will help you to find your own suitable solutions. I am a devoted fan of auto-enrollment for certificates.AD Certificate Services is the Server Role that allows us to build a public key infrastructure PKI and provide digital certificate and digital signature for our organization.

I will utilize existing DC in my network which I deployed in previous part and install CA roles on it. Upon selecting the role, you will be prompted to confirm the installation of additional features.

Go ahead and click on Add Features and click Next. Make sure to allow additional features to be installed. Click Next through the remaining screens until you reach the last page where you click on the Install. Click on it.

On the Cryptography screen, leave the key lenght as default and be sure that hash algorithm is set to SHA Click next. We can modify Common name if we want to. Common name does not have to match server name.

Many subscribers of ITOpsTalk. Step 1: Backup Windows Server R2 certificate authority database and its configuration. CA Backup complete. The screenshots below show the server name as WS to highlight which server we are working on. This step-by-step highlights screenshots from Windows Server Windows Server process is the same with similar screenshots.

Server Certificate Deployment Planning

I am currently working on writing another post that will address the need to have servers with different names. Stay tuned. Also, if we have an offline root, is the process basically the same, we'd just choose the appropriate CA type for the root and the intermediate server?

I updated the note found in the beginning of Step 4 to address this. I take it the process is the same for any subordinate CA's? And should the subordinates be done after the root CA? The above does not work for all scenarios hence the reason more research is being conducted. Thank you in advance for your patience.

My environment is a R2 offline root, and R2 intermediate and ocsp responder servers. All of which I would like to get onto Server Glad you are talking to this point but frankly there are many more details to the migration that is missing.

A couple of items of note in your process:. You backup the CA while it is in production which means it could issue certificates after the backup and before you remove the role. I always recommend you note the templates that are installed on the CA, and then remove them from the CA. This prevents any further issuance. Now your backup will be accurate and no issued certificate details will be lost.

After moving to the new platform, add back the appropriate templates. So this object needs to be updated to allow the new computer object to publish the CRL.

Thank you for the additional information. I have found other tech blogs where the discuss getting the capolicy. My CRL site is on a third server, that only does that. I do need to migrate that to a newer OS server as well. Also, does anyone have any thoughts on my questions above?

Or some actual official MS documentation on this topic, even if it is missing several steps? No need to specifically upgrade your CRL Webserver, unless it too is going end of life. Here is the Microsoft official migration doc.

It's old, but still applicable. Usual caveots as I pointed out. There are some gotchas to the method they have you follow remember you should remove templates before backups, etc.
