After uninstalling Symantec Enpoint Protection (manually) one computer (Windows XP) has an inoperative NIC; it shows up in device manager as conflicted.

I'm reposting some of my own troublshooting logs so people outside our network can benefit. There certainly may still be other/better ways. – Justin Love Apr 30 '09 at 19:04
