Step-by-Step Example Deployment of the PKI Certificates Required for AMT and Out of Band Management: Windows Server 2008 Certification Authority

Updated: June 1, 2010

Applies To: System Center Configuration Manager 2007 R2, System Center Configuration Manager 2007 R3, System Center Configuration Manager 2007 SP1, System Center Configuration Manager 2007 SP2

This step-by-step example deployment, which uses a Windows Server 2008 certification authority (CA), contains procedures that guide you through the process of creating and deploying the public key infrastructure (PKI) certificates that Configuration Manager 2007 SP1 and later requires for out of band management and AMT. For more information about out of band management in Configuration Manager, see Overview of Out of Band Management.

noteNote
The information in this topic applies only to Configuration Manager 2007 SP1 and later.

The procedures in this example use Active Directory Certificate Services, using Windows Server 2008, Enterprise Edition, with an enterprise CA and certificate templates. The steps are appropriate for a test network only, as a proof of concept.

Because there is no single method of deployment for the required certificates, you will need to consult your particular PKI deployment documentation for the necessary procedures and best practices to deploy the required certificates for a production environment. For more information about the certificate requirements for AMT and out of band management, see Certificate Requirements for Out of Band Management.

ImportantImportant
AMT provisioning in Configuration Manager 2007 SP1 and later requires Microsoft Active Directory Certificate Services, using an enterprise CA and certificate templates. For more information about the certificate deployment requirements and usage, see About Certificates for Out of Band Management.

Test Network Requirements

The example has the following requirements:

  • The test network is running Active Directory Domain Services with Windows Server 2008, and it is installed as a single domain, single forest.

  • You have a domain controller running Windows Server 2008, Enterprise Edition, which has the following server role installed: Active Directory Certificate Services installed as an enterprise root CA.

  • You have one computer that has Windows Server 2008 (Standard Edition or Enterprise Edition) installed and is designated as a member server.

  • You can log in with a root domain administrator account or an enterprise domain administrator account and use this account for all the procedures in this example deployment.

Overview

PKI certificates must be prepared and installed prior to managing computers out of band in Configuration Manager 2007 SP1 and later. This example provides the steps to deploy the certificates required for provisioning computers for AMT so that they can be managed out of band. For more information about configuration of Configuration Manager 2007 SP1 and later for out of band management, see Configuring Out of Band Management.

The following table lists the PKI certificates that are required for managing AMT computers out of band and describes how they are used in a Configuration Manager 2007 site.

 

Certificate Requirement Certificate Description

AMT provisioning certificate

This certificate is used to prepare AMT-based computers for out of band management by Configuration Manager 2007 SP1.

For more information about AMT provisioning, see About AMT Provisioning for Out of Band Management.

Web server certificate

This certificate is requested by the primary site server on behalf of AMT-based computers and then installed in the AMT firmware in the computers.

After this certificate is installed, it authenticates the AMT-based computers to the out of band service point site system server and to computers running the out of band management console, and encrypts all data transferred between them using Transport Layer Security (TLS).

Client authentication certificate

Applicable to Configuration Manager 2007 SP2 only: If you will manage AMT-based computers out of band when they are on an 802.1X authenticated wired or wireless connection, this might require the use of a client authentication certificate (required with EAP-TLS authentication and optional with EAP-TTLS/MSCHAPv2 and PEAPv0/EAP-MSCHAPv2 authentication methods). This certificate is requested by the primary site server on behalf of AMT-based computers and then installed in the AMT firmware in the computers.

After this certificate is installed, it is used to authenticate the AMT-based computer to the RADIUS server so that it can be authenticated and authorized for network access.

For more information about the certificates, see Certificate Requirements for Out of Band Management.

Follow the steps in this example to achieve the following goals:

  • Create Windows security groups to be used with the certificate templates.

  • Request, install, and prepare the AMT provisioning certificate.

  • Prepare Web server certificates by configuring a certificate template on the issuing CA.

  • Applicable to Configuration Manager 2007 SP2 only: Prepare client authentication certificates for use with 802.1X client authentication by configuring a certificate template on the issuing CA.

Creating Windows Security Groups for the Site System Servers

Use the following procedure to create Windows security groups for the site system servers. These security groups will be used to help ensure that only the required servers can use the two certificate templates required for AMT provisioning.

To create Windows security groups for the site system servers

  1. On the domain controller, click Start, click Administrative Tools, and then click Active Directory Users and Computers.

  2. Right-click the domain, click New, and then click Group.

  3. In the New Object – Group dialog box, enter ConfigMgr Primary Site Servers as the Group name, and then click OK.

  4. In Directory Users and Computers, right-click the group you have just created, and then click Properties.

  5. Click the Members tab, and then click Add to select the member server.

  6. Click OK, and then click OK again to close the group properties dialog box.

  7. Repeat steps 2 through 6, this time naming the group ConfigMgr Out of Band Service Points.

  8. Restart your member server (if running) so that it can pick up the new group membership.

    noteNote
    In the test environment, there is only one server to add, which will be used for both the primary site server and the out of band service point. However, in a production environment, it is likely that you will have multiple primary sites that will support out of band management and that you will install the out of band service point on a different server than the site server. It is therefore good practice to assign permissions to two groups and add all your primary site servers to one group and all your out of band service point site systems to the other group.

    Creating security groups for these servers enables you to assign permissions so that only these servers can request these certificates.

Requesting, Installing, and Preparing the AMT Provisioning Certificate

This step has the following procedures:

Request the provisioning certificate from your internal CA only if the AMT-based computers are configured with the certificate thumbprint of your internal root CA. For more information about choosing between an external CA and using your internal CA, see About Certificates for Out of Band Management. For help with locating your internal root certificate thumbprint, see How to Locate the Certificate Thumbprint of Your Internal Root Certificate for AMT Provisioning.

Requesting and Installing the AMT Provisioning Certificate from an External CA

Use the instructions from the company issuing the AMT provisioning certificate, which will often involve requesting the certificate from the company’s public Web site. You might also find detailed instructions for your chosen external CA on the Intel vPro Expert Center: Microsoft vPro Manageability Web site (http://go.microsoft.com/fwlink/?LinkId=132001).

ImportantImportant
External CAs might not support the Intel AMT provisioning object identifier. When this is the case, use the alternative method of supplying the OU attribute of Intel(R) Client Setup Certificate.

The AMT provisioning certificate from an external CA should be installed into the Computer Personal certificate store on the member server that will host the out of band service point. When this procedure is complete, it is ready to be prepared for the out of band management component.
