Hi, I'm having an SBS2003 with ISA2004 that is faulting with this error The Firewall service stopped because an application filter module C:\WINDOWS\system32\msvcrt.dll generated an exception code C0000005 in address 77B96F76 when function CompleteAsyncIO was called. To resolve this error, remove recently installed application filters and restart the service. I usually see this kind of error with the third-pary web filters, but in this case it references a system library. Anyone seen something like this ?
