My firewall service stops any time I have a power surge, even for a fraction of a second. I do have a UPS attached to my switches. this did not happen before with ISA 2000. is there a setting I need to know about. All my other server also show that the Intel NIC was reconnected, but they are all up and running; except ISA firewall service which I have stop and restarted, even though it says running. the NIC is on a Power edge 2800 Dell server. thanks
