Rafeeq, followed your procedure, still the same after reboot. Regarding the Device Driver, what exactly are you referring to? I looked at device manager, nothing is listed wrong or driver missing there. BTW, if I do a repair of SEP 12.1, the firewall problem will temporary goes away, until I reboot.
J.Bonner, I've already tried using CleanWipe, I also emptied any Symantec related directories on my C:\ drive, as well as deleting the remaining entries from the registry.
Paul, here's what I got: [SC] EnumQueryServicesStatus:OpenService FAILED 1060:
Thanks everyone.
