FIX: DefaultAppPool may crash when you try to install Forefront UAG Service Pack 1 Update 1
Article ID: 2655007 - View products that this article applies to.
Consider the following scenario:
In this scenario, when you select the array manager under Nodes in Array Monitor, the default application pool (DefaultAppPool) crashes.
This issue occurs because the Forefront UAG array expects a certain parameter response from the array nodes when the array is enabled in Array Monitor. When this issue occurs, a NULL pointer is passed as a parameter because of a problem in the logic, and an exception occurs.
To resolve this issue, install the rollup package that is described in the following Microsoft Knowledge Base article:
(http://support.microsoft.com/kb/2647899/ )Rollup 1 for Forefront Unified Access Gateway (UAG) 2010 Service Pack 1 Update 1
To work around this issue, upgrade the array nodes to the same build as the array manager before you continue with the installation of Service Pack 1 Update 1 on the server.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
