  • Article

Applies To: Unified Access Gateway

When working with Forefront Unified Access Gateway (UAG) in an array that uses Network Load Balancing (NLB), you must take care when installing Service Pack 2. This topic describes how to install SP2 on a Forefront UAG array that is using NLB.

Note the locations of the Setup log files that can help you to troubleshoot installation issues:

  • Setup log files for Forefront TMG are located at %windir%\Temp.

  • Setup log files for Forefront UAG are located at %ProgramData%\Microsoft\UAG\Logs.
