I cannot start the fwsrv.exe service on ISA Serer 2006 firewall. I am seeing Service-Specific error codes 3321488523, -2146893802 qnd -2148073494; as well as 7001 and 7024. The Server Control Service starts and immediately shuts down as if it has no tasks to complete. All dependencies for the firewall seem to be Started. The IIS Cert has been reapplied and the server restarted several times. This Celestix "Whale" appliance has been down 4 days now and I am just stepping into a mess. Any suggestions as to how to approach this? It appears that IAG v3.7-SP2 Update-2 Build 37 was just applied (Just the Update 2 portion). Everything worked fine before this update according to users.
