This topic provides guidance for diagnosing and resolving the following installation issues you may encounter with Forefront Unified Access Gateway (UAG):

Installation fails from a network drive

Cause: Setup installs, and then activates Forefront TMG as a prerequisite before continuing to install Forefront UAG. After Forefront TMG is operational, all network traffic is denied by default, and the installation of Forefront UAG fails.

Solution: No workaround. Install Forefront UAG from a local drive.

Installation fails if Windows Error Reporting tool is running

Cause: To verify if this is the cause of the setup failure, in the file %program files%\Microsoft SQL Server\100\setup bootstrap\Logs\WatsonX64_Cpu64_1_ComponentUpdate, look for the following: Info 1603. The file C:\Program Files\Common Files\Microsoft Shared\DW\DW20.EXE is being held in use. Close that application and retry.

Solution: Restart the computer, and then run Setup again.

Installation fails if the machine name contains lower-case letters

Cause: To verify if this is the cause of the setup failure, in the file %program files%\Microsoft SQL Server\100\setup bootstrap\Logs\WatsonX64_Cpu64_1_ComponentUpdate, look for the following: Object reference not set to an instance of an object.

Solution: Rename the computer with upper-case letters, restart the computer, and then run Setup again.

Installation fails with Group Policy enforcement of Windows Firewall

Cause: The installation does not complete successfully when Setup tries to disable the Windows Firewall and fails to do so.

Solution: No workaround.

Installing Forefront UAG on a pre-hardened operating system is unsupported

Cause: The installation does not complete successfully when Setup tries to install the following operating system roles and features (if they are not already installed):

  • .NET Framework

  • Windows Installer

  • WWSAPI

  • NPAS-Policy-Server

  • NPAS-RRAS-Services

  • ADLDS

  • RSAT-Web-Server

  • NLB

  • PowerShell

  • RDG (a.k.a. TSG)

Solution: No supported workaround. The operating system should be hardened after Forefront UAG installation.
