Hey folks – since the TLGs are typically put up only in the download center, it makes discoverability of some of the cool content inside of them hard when it comes to search engines. Therefore, I’m going to post the full text of the TLGs on the Edge Man blog. However, I recommend that you download the Word .doc version of the TLGs when you actually put together your Test Lab using the Test Lab Guides.
For a downloadable version of the Test Lab Guide – Demonstrate UAG SP1 RC DirectAccess Connectivity Assistant check out:
DirectAccess is a new feature in the Windows 7 and Windows Server 2008 R2 operating systems that gives users the experience of being seamlessly connected to their intranet any time they have Internet access. With DirectAccess enabled, requests for intranet resources (such as e-mail servers, shared folders, or intranet Web sites) are securely directed to the intranet, without requiring users to connect to a VPN. DirectAccess provides increased productivity for a mobile workforce by offering the same connectivity experience both inside and outside the office.
Forefront Unified Access Gateway (UAG) SP1 RC extends the value of the Windows DirectAccess solution by adding features that meet the requirements of many enterprise deployments:
- 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.
To learn more about UAG DirectAccess, see the following resources:
The Microsoft DirectAccess Connectivity Assistant (DCA) supports a DirectAccess client computer that is running Windows 7 by clearly indicating the state of DirectAccess connectivity to corporate network resources. It provides easy access to troubleshooting information and makes it simple to create and send log files to support personnel.
Without the DCA, when a user’s Internet connection (for example, http://www.bing.com) appears to be available, but corporate network resources are not accessible, there is no way that the user can verify if the problem is caused by DirectAccess not working correctly. This can result in user frustration and increased Help Desk support calls. The DCA clearly indicates the operational status of DirectAccess by using an icon in the notification area and informational messages. This helps the user identify the problem area and helps direct troubleshooting efforts.
If DirectAccess is not working correctly, the DCA clearly indicates the status by changing the icon in the notification area and by sending informational messages that provide more detail about the failure. The DCA provides the user with easy access to an extranet URL. For example, this URL might point to a Web site that hosts support information for the organization’s user community. The user can easily send diagnostic log files to the DirectAccess support staff. The log files can contain the default information. The UAG SP1 RC DCA includes comprehensive advanced diagnostics built-in. The administrator can also include a script in the DCA configuration that creates additional diagnostic information that is included in the log files sent to the support team.
This guide provides step-by-step instructions for configuring UAG DirectAccess SP1 RC with the DirectAccess Connectivity Assistant in a test lab so that you can see how it works. You will set up and deploy UAG DirectAccess SP1 RC using five server computers, two client computers, Windows Server 2008 R2 Enterprise edition, and Windows 7 Ultimate Edition. The Test Lab simulates intranet, Internet, and a home networks, and demonstrates the Forefront UAG DirectAccess Connectivity Assistant. The starting point for this paper is the Test Lab Guide: Demonstrate UAG SP1 RC DirectAccess .
These instructions are designed 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 show clearly the required functionality. This configuration is not designed to reflect best practices, nor does it reflect a required or recommended configuration for a production network. The configuration, including IP addresses and all other configuration parameters, is designed to work only on a separate test lab network. For more information on planning and deploying DirectAccess with Forefront UAG, please see the Forefront UAG DirectAccess design guide and the Forefront UAG DirectAccess deployment guide
In this test lab scenario, Forefront UAG DirectAccess SP1 RC is deployed with:
- One computer running Windows Server 2008 R2 Enterprise Edition (DC1), that is configured as an intranet domain controller, Domain Name System (DNS) server, Dynamic Host Configuration Protocol (DHCP) server, and an enterprise root certification authority (CA).

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 , please refer to the Forefront UAG DirectAccess Deployment Guide for the steps to configure the UAG DirectAccess server and supporting infrastructure servers.
The following sections describe how to configure UAG1, DC1 and CLIENT1 for UAG SP1 RC and the DCA. After UAG1, DC1 and CLIENT1 are configured, this guide provides steps for demonstrating the DCA functionality for CLIENT1 when it is connected to the Homenet subnet.
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.
The following procedures are performed to enable and allow you to test the UAG SP1 RC DCA:
· 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: Configure INET1 with a Help.txt file. The DCA can provide DirectAccess users information about a web site they can go to in order to get help with DirectAccess related problems. In this step you will configure a web page that CLIENT1 can reach to get that help.
· Step 3: Install and Configure the Web Server Role on DC1. The DCA uses a number of connectivity verifiers to determine intranet connectivity over the DirectAccess IPsec tunnels. In this step you will configure DC1 as a web server so that the DCA can use HTTPS to DC1 for a connectivity verifier.
· Step 4: Run the UAG DirectAccess DCA Configuration Wizard on UAG1. UAG SP1 RC includes a new integrated DCA wizard that automatically configures and deploys GPO settings that enable the DCA. In this step you will run the UAG SP1 RC DCA wizard.
· Step 5: Update Group Policy on CLIENT1 and Test DCA Functionality. The new DCA settings are deploy via the DirectAccess clients GPO. In this step you will update Group Policy on CLIENT1 and then test some of the DCA features.
· Step 6: 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.
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.
The first step is to complete all the steps in the Test Lab Guide: Demonstrate UAG SP1 RC DirectAccess. After completing the steps in that Test Lab Guide you will have the core infrastructure required to complete this Test Lab Guide on how to configure the UAG DirectAccess DCA. If you have already completed the steps in that Test Lab Guide and saved a snapshot or disk image of the Test Lab, you can restore the snapshot or image and begin with the next step.
STEP 2: Configure INET1 with the Help.txt File
The DCA can expose to DirectAccess users a link to a location where they can find help. This location is configured in the UAG DirectAccess DCA wizard. In this step you will configure a Help.txt file that CLIENT1 will connect to when acting as a DirectAccess client.
- *At the INET1 computer or virtual machine, log on as Administrator. Click the Start button, click the Windows Explorer icon in the Task Bar.
- In Windows Explorer, navigate to C:\inetpub\wwwroot. In the right pane of the Windows Explorer windows, right click in an empty area, point to New and click Text Document.

STEP 5: Update Group Policy, Install the DCA and Test DCA Functionality on CLIENT1
In this step you will update Group Policy on CLIENT1 so that it receives the new DCA related settings. Then you will install the DCA client software and finally test DCA functionality when CLIENT1 is located on the Homenet subnet.
Update Group Policy on CLIENT1:
- *Connect CLIENT1 to the Corpnet subnet. Wait until the network icon in the notification area of the desktop displays a yellow caution sign.
- Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. Click Yes at the User Account Control prompt.
- In the command prompt window, enter gpupdate /force and press ENTER. Wait for the command to complete and then close the command prompt window.
Install the DCA software on CLIENT1:
- On CLIENT1, insert the UAG SP1 RC DVD into the computer or mount the UAG SP1 RC .iso file on the virtual machine. In the AutoPlay dialog box, click Open folder to view files.
- Navigate to the UAG\Microsoft Forefront Unified Access Gateway\common\bin\da\dca folder. Double click on the Microsoft_DirectAccess_Connectivity_Assistant file.
- In the Microsoft DirectAccess Connectivity Assistant Setup wizard, on the MICROSOFT PRE-RELEASE SOFTWARE LICENSE TERMS page, put a checkmark in the I accept the terms in the License Agreement checkbox and click Install. In the user Account Control dialog box, click Yes. On the Completed the Microsoft DirectAccess Connectivity Assistant Setup Wizard page, click Finish.
- You should now see the DCA icon in the system notification area.
Test DCA Functionality on CLIENT1:
- Move CLIENT1 to the Homenet subnet and wait for the network icon in the system notification area to stop spinning. Right click the Taskbar and click Properties. In the Taskbar and Start Menu Properties dialog box, in the Nofication Area section, click Customize. On the Nofication Area Icons page, put a checkmark in the Always show all icons and notifications on the taskbar and click OK. Click OK in the Taskbar and Start Menu Properties dialog box.
- At this point you might notice a red “x” on the DCA icon. Open an elevated command prompt on CLIENT1. In the command prompt window enter net view \\dc1 and press ENTER. You should see a list of shares on DC1. In the command prompt window, enter net view \\app1 and press ENTER. If you receive a network path was not found error, then in the command prompt window enter ipconfig /flushdns and press ENTER. After that command completes, enter in the command prompt windows net view \\app1 and press ENTER. You should see a list of share on APP1. You should also see the red “x” disappear from the DCA icon.
- *Move to the APP1 computer or virtual machine. Open Windows Explorer and navigate to the C:\Files folder. Right click the Example file and click Rename. Rename the file to Example1 and press ENTER to save the file with the new name. Notice that a new empty file is created with the same name.
- *Move to the DC1 computer or virtual machine. Click Start and point to Administrative Tools. Click Internet Information Services (IIS) Manager. In the Internet Information Services (IIS) Manager console, in the left pane, click DC1 (CORP\User1). In the Actions pane, click Stop.
- *Move to the CLIENT1 computer or virtual machine and wait a few moments. You will notice that the DCA icon now has a red “x” on it. Right click the DCA icon and click Advanced Diagnostics.
- Notice under Advanced Log File that is says generating logs while it creates the log files. When it says Open logs directory click the Open logs directory link. Double click DcaDefaultLog.
- On the DirectAccess Connectivity Assistant Logs web page, note in the Probes List section a line that reads FAIL – The server name resolved successfully, but failed to access HTTP: https://dc1.corp.contoso.com. Note that the other two connectivity verifiers that you configured show as PASS. Also note that there is a connectivity verifier that you didn’t configure – a ping test to the UAG DirectAccess server itself (PASS – PING: 2002:836b:3::836b:3). Scroll through the rest of the page to view the detailed information collected by the DCA client software. Close Internet Explorer. Close Windows Explorer.
- In the DCA dialog box, notice that the entry you make in the wizard DirectAccess Help Center appears, and under that is the URL you configured for the Help page. Click the http://inet1.isp.example.com link. You should see the help page that reads This is the place to get help with your DirectAccess problems. Close Internet Explorer. Note the Email Logs button. If there were an email client application installed on CLIENT1, you could click that button and it would automatically email the log files to firstname.lastname@example.org, as you configure in the DCA wizard. Click Close in the Microsoft DirectAccess Connectivity Assistant dialog box. Close all open windows on CLIENT1.
- *Move to the DC1 computer or virtual machine. In the Internet Information Services (IIS) Manager console, in the Actions pane, click Start. Close all open windows on DC1.
It is important to note that the DCA icon may show a red “x” even when there is connectivity to the intranet. The red “x” appears when any of the connectivity verifiers is unavailable to the DirectAccess client. It is recommended that you specify a diverse set of resources for your connectivity verifiers. This diversity helps ensure that a failure to access a resource is an unambiguous indication of a problem with DirectAccess rather than a problem with another component.
For example, if all of the specified resources are behind a network address translating application layer gateway (NAT64), the failure of DCA to access the test resources might indicate a failure of the NAT64 rather than a failure of DirectAccess. Instead, identify one resource behind the NAT64, another behind an ISATAP gateway, and so on. Also note that you must not use the Network Location Server as a connectivity verifier, since the name of the Network Location Server cannot be resolved by the DirectAccess client.
This completes the UAG SP1 RC DirectAccess Connectivity Assistant test lab. To save this configuration so that you can quickly return to a working UAG SP1 RC DirectAccess Connectivity Assistant configuration from which you can test other DirectAccess modular TLGs, TLG extensions, or for your own experimentation and learning, do the following:
1. On all physical computers or virtual machines in the test lab, close all windows and then perform a graceful shutdown.
2. If your lab is based on virtual machines, save a snapshot of each virtual machine and name the snapshots TLG UAG DirectAccess SP1RC DCA. If your lab uses physical computers, create disk images to save the DirectAccess test lab configuration.
