Enable Web Server Certificate Requests On Windows Server 2008R2 CA Server

So I’ve run into this problem multiple times and ‘hacked’ my way around it various ways, but there is a better way that doesn’t require the use of certutil.exe or any other console utilities.  This scenario applies under the following conditions:

  • CA (Certificate Authority) Server is running on Windows Server 2008 R2
  • Web Server is running on Windows Server 2008 R2
  • Both servers are members of the same domain
  • You want to use the Certificates snap-in
  • You want to stay away from the console if you can

By default, you cannot generate a web server certificate request directly from your servers and you are presented with this screen based on the default Active Directory Enrollment Policy:

001 denied

As you can see from the screenshot, most of the certificate templates are unavailable with the exception of the computer certificate template.

Install Certificate Services on Windows Server 2008 R2

This post picks up where the last post left off.  In the last post, we created a Windows Server 2008 R2 Active Directory Domain Controller and stopped short of going on to add Certificate Services into the mix.

If you’re not sure if you need certificate services for your environment, it never hurts to have it available.  It does not add much overhead so for development environments and small businesses you can consider adding the role to a DC (domain controller) as we are here.  Certificate Services will allow you to issue certificates to your internal resources, use client/server certificates for authentication, and set up SSL enabled websites.

I believe best practice is, and I’m sure someone will correct me if I’m wrong, to set up an Enterprise Root CA (Certificate Authority), then set up one or more subordinate CA’s.  You can then make your Root CA unavailable for access and have the subordinates handle all of the traffic without fear of compromising your Root CA.  In this tutorial, we’ll just be installing and configuring a Root CA, but the process is basically the same for the subordinates.

Now that you’ve got some background information, onto the installation/configuration of Windows Server 2008 R2 Certificate Services.

In ‘Server Manager’, select Roles in the left pane, then Add Roles in the right pane.  Place a check mark in the checkbox for Active Directory Certificate Services.  Then click Next.
