I need to resolve the following recurring error (triggered after the firewall service crashes) on Microsoft Forefront TMG 2010 (SP2): -
"The Firewall service stopped because an application filter module C:\Program Files\Microsoft Forefront Threat Management Gateway\MSPHLPR.dll generated an exception code C0000005 in address 0000000071F8E60E when function CompleteAsyncAccept was called. To resolve this error, remove recently installed application filters and restart the service."
As far as I'm aware, the issue was resolved in Rollups 2-5 but they are no longer available online, even though SP2 is still available. For various reason, I don't have the option to switch from TMG. Any assistance in this regard would be highly appreciated. Thanks.
