Re: ethernet error? [SOLVED]
Ahhh, that's it, the firewall! I am my own worst enemy. I installed
Guarddog, and I was blocking IPP (Internet Printing Protocol).
Unblocking it made the nasty messages go away.
Thanks to everyone who replied. Without your help, I probably would have
replaced my motherboard instead!
I still highly recommend Guarddog.
regards & happy holidays,
Robert
