Here’s a new Knowledge Base article we published recently. This one talks about a fix for an issue where the TMG 2010 firewall service crashes frequently and logs an Event ID 14057.
Consider the following scenario:
Source: Microsoft Forefront TMG Firewall Event ID: 14057 Description: The Firewall service stopped because an application filter module C:\Program Files\Microsoft Forefront Threat Management Gateway\w3filter.dll generated an exception code C0000005 in address 000000007043254F when function CompleteAsyncIO was called. To resolve this error, remove recently installed application filters and restart the service.
This issue occurs because of a known problem that was introduced by Service Pack 2 for Forefront Threat Management Gateway 2010.
To resolve this issue, install the hotfix package that is described in the following Microsoft Knowledge Base article:
2649961 Rollup 1 for Forefront Threat Management Gateway (TMG) 2010 Service Pack 2
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
For the most current version of this article please see the following:
