Modifying the Forefront UAG DirectAccess export script

Published: January 11, 2010

Updated: February 1, 2011

Applies To: Unified Access Gateway

On completion of the Forefront UAG DirectAccess Configuration Wizard, you can apply the configuration settings immediately or export them to an export script. In certain cases, you might want to modify parameters in the exported script before you apply it; for example, if you want to populate some of the parameters manually instead of using the Forefront UAG DirectAccess Configuration Wizard, or if you want to perform configurations that cannot be done in the wizard, such as changing the name of Group Policy objects (GPOs) created by Forefront UAG DirectAccess.

This topic describes how to edit parameters in the export script that is created at the end of the Forefront UAG DirectAccess Configuration Wizard.

WarningWarning:
Unless you are familiar with the parameters in the export script, it is recommended that you do not make any changes.

The export script can include runtime or static parameters. You can modify the export script parameters depending on their type, as follows.

To modify the export script parameters

  1. On the taskbar, click Start, click All Programs, click Accessories, click Windows PowerShell, right-click Windows PowerShell, and then click Run as administrator.

  2. From the PowerShell command prompt, type ./script.ps1 –Parameter Name "Example".

    noteNote:
    See the tables that follow this procedure for a description of the runtime and static parameters that you can modify.

  3. You can also modify the static script parameters as follows:

    1. Open the export script using notepad, and referring to the Static Parameters table that follows this procedure, modify the relevant parameters in the export script, and then save the script.

    2. On the taskbar, click Start, click All Programs, click Accessories, click Windows PowerShell, right-click Windows PowerShell, and then click Run as administrator.

    3. From the Windows PowerShell command prompt, run the modified script file.

  4. In the Forefront UAG Management console, click the Activate configuration icon, and then on the Activate Configuration dialog box, click Activate to start the configuration.
