This is the text of the Test Lab Guide: Demonstrate Forefront UAG SP1 RC DirectAccess with Network Access Protection (NAP) Test Lab Guide, which you can download at http://go.microsoft.com/fwlink/?LinkId=205354  

I am posting the entire text of the Test Lab Guide here with the goal that the community can improve on the Test Lab Guide by adding new options, demonstrating new features, or just correct errors in the text :)  In fact, you can make any changes you like - that is the nature of a wiki. I'm looking forward to seeing how you all can make this great Test Lab Guide even better!

========================================================

Introduction

• Support for arrays of up to 8 UAG DirectAccess servers where configuration is done once on an array master and is automatically deployed to all other members of the array
• Support for Network Load Balancing, which enables the UAG DirectAccess SP1 RC array to be highly available without requiring the use of an external hardware load balancer
• Support for IPv4-only networks, network segments, or server or application resources with the help of NAT64/DNS64 IPv6/IPv4 transition technologies.

Important

The following instructions are for configuring a test lab using the minimum number of computers. Individual computers are needed to separate the services provided on the network and to clearly show the desired functionality. It is important to remember that this configuration is neither designed to reflect best practices nor does it reflect a desired or recommended configuration for a production network. The configuration, including IP addresses and all other configuration parameters, is designed only to work on a separate test lab network.

Attempting to adapt this test lab configuration to a pilot or production deployment can result in configuration or functionality issues. To ensure proper configuration and operation of UAG DirectAccess with NAP for your pilot or production DirectAccess deployment, use the information in Planning Forefront UAG DirectAccess with Network Access Protection (NAP) for your planning and design decisions and Forefront UAG DirectAccess Deployment Guide for the steps to configure the UAG DirectAccess server and supporting infrastructure servers.

Steps for configuring the test lab

Note

You must be logged on as a member of the Domain Admins group or a member of the Administrators group on each computer to complete the tasks described in this guide. If you cannot complete a task while you are logged on with an account that is a member of the Administrators group, try performing the task while you are logged on with an account that is a member of the Domain Admins group. For all tasks described in this document you can use the CONTOSO\User1 account created when you went through the steps in the UAG DirectAccess Test Lab Guide: Demonstrate UAG SP1 RC DirectAccess.

·         Step 1: Complete the Demonstrate UAG SP1 RC DirectAccess Test Lab Guide – The first step is to complete all the steps in the Test Lab Guide: Demonstrate UAG SP1 RC DirectAccess.

·         STEP 2: Install the CA Server Role on APP1. In this step you will install a subordinate Certification Authority on APP1 so that it will be able to create health certificates for DirectAccess NAP clients.

·         STEP 3: Configure the Subordinate CA and CA Permissions on APP1. In this step you will configure the subordinate CA on APP1 so that it will automatically grant certificates when requested by the UAG1, which is configured as a Health Registration Authority. You will also configure permissions on the CA to enable UAG1 to issue and manage certificates, manage the CA and request certificates.

·         STEP 4: Configure UAG1 as an NPS Server and NAP health Registration Authority (HRA). In this step you will reconfigure the DirectAccess settings on UAG1 to support NAP policy enforcement for DirectAccess clients. After you complete this step, UAG1 will be configured as a Network Policy Server that provides NAP server functionality, as well as a Health Registration Server (HRA).

·         STEP 5: Verify NAP Configuration on CLIENT1. In this step you will confirm that CLIENT1 received the Group Policy settings required for NAP clients and confirm that CLIENT1 received a health certificate from UAG1.

·         STEP 6: Install Microsoft Security Essentials on CLIENT1. In this step you will connect CLIENT1 to a live portion or your network so that it can download and install Microsoft Security Essentials.

·         STEP 7: Confirm that CLIENT1 Passes NAP Evaluation. In this step you will move CLIENT1 to the Homenet subnet and confirm that CLIENT1 can pass NAP evaluation and access resources on the intranet through the intranet tunnel.

·         STEP 8: Confirm that CLIENT1 cannot access the Intranet Tunnel when NAP Non-Compliant. In this step you will confirm that when CLIENT1 does not meet health requirements it will not be able to connect to resources through the DirectAccess intranet tunnel.

·         Step 9: Snapshot the configuration. After completing the Test Lab, take a snapshot of the working UAG DirectAccess with NAP Test Lab so that you can return to it later to test additional scenarios.

Note

You will notice that there are several steps that begin with an asterisk (*). The * indicates that the step requires that you move to a computer or virtual machine that is different from the computer or virtual machine you were at when you completed the previous step.

7. In the Select Computer dialog box, select Local computer and click Finish.
8. In the Add or Remove Snap-ins dialog box, click OK.
9. In the left pane of the console window, navigate to Certificates (Local Computer)\Personal\Certificates. In the middle pane of the console, notice that there is a certificate issued by corp-APP1-SubCA. Double click on that certificate.
10. In the Certificate dialog box, on the General tab, note that in the This certificate is intended for the following purposes(s): section that one of the intended purposes is System Health Authentication. This indicates that CLIENT1 has passed NAP inspection and should now have access to the intranet tunnel.
11. In the Certificate dialog box, click OK. Minimize the Console1 window.
12. Click Start and in the Search box, enter \\app3\files and press ENTER.
13. Double click on the Example file. You can now read the contents of that file. This confirms that you have access to the Corpnet subnet over the intranet tunnel, since APP1 is not a member of the infrastructure servers group. Close the Windows Explorer window that shows the contents of the Files share. Close the Notepad window.
14. Click Start and then enter wf.msc in the Search box and press ENTER.
15. In the middle pane of the console, note that the Private Profile is Active. DirectAccess clients will only establish their DirectAccess tunnels to the DirectAccess server when either the Public or Private Profiles are active.
16. In the right pane of the console, click Properties. In the Windows Firewall with Advanced Security dialog box, click the down arrow next to Firewall state and click Off. Click OK. You will see two balloons appear in the system notification area. One will ask that you turn on the Windows Firewall and the second will inform you that network access may be limited. Note in the middle pane that it says Windows Firewall is off. Click Refresh in the right pane. NAP auto-remediation automatically enabled the Windows Firewall after it was turned off.
17. In the left pane of the console, navigate to Windows Firewall with Advanced Security\Monitoring\Security Associations\Main Mode. Notice the Main Mode entry that has User (Kerberos V5) as the second authentication method. This indicates that the user was able to access the intranet tunnel since the intranet tunnel requires user authentication. In addition, when NAP is enabled for DirectAccess clients, the computer certificate used to authenticate the intranet tunnel is the Health Certificate, indicating that the computer was able to pass NAP inspection.
18. Minimize the Windows Firewall with Advanced Security window.

STEP 8: Confirm that CLIENT1 cannot access the Intranet Tunnel when NAP Non-Compliant

1. On CLIENT1, click Start and then in the Search box, enter services.msc and press ENTER.
2. In the right pane of the Services console, double click on Microsoft Antimalware Service.
3. In the Microsoft Antimalware Service Properties (Local Computer) dialog box, click the Stop button.  Click OK and then minimize the Services console.
4. Notice that a Network Access Protection Network access might be limited balloon appears. This indicates that CLIENT1 no longer passes NAP inspection. In the Microsoft Security Essentials dialog box, click the Close control button (the “x” in the upper right) to close the dialog box.
5. Restore the console window that has the Certificates snap in installed. Right click the middle pane and click Refresh. Notice that the health certificate no longer appears. When the client does not pass NAP inspection, the certificate is removed from the machine’s computer store.
6. Restore the Windows Firewall with Advanced Security console and click Refresh in the right pane of the console. Notice that the Main Mode security association using Kerberos V5 as the 2^nd Authentication Method is no longer there. This indicates that the client is no longer able to establish the intranet tunnel because it cannot provide a health certificate for computer authentication.
7. Click Start and enter \\app1\files in the Search box and press ENTER. After a few moments you will see a Network Error dialog box indicating that Windows cannot access the share. This is consistent with the fact that CLIENT1 needs access to the intranet tunnel to access APP1 and the fact that the intranet tunnel is not available because CLIENT1 current does not pass NAP inspection. Click Cancel in the Network Error dialog box.
8. Click Start and enter \\dc1\files in the Search box and press ENTER. In this case the Files share is available. The reason for this is that access to servers in the infrastructure servers list is accessible over the infrastructure tunnel.
9. Restore the Services console and right click Microsoft Antimalware Service and click Start.
10. Click Start and enter \\app1\files in the Search box and press ENTER. You can now access APP1 over the intranet tunnel because CLIENT1 is able to pass NAP inspection.
11. Close all open windows on CLIENT1 and do not save the changes to any of the mmc consoles.
