I did an upgrade install Friday in my eMac to OS 10.3 and today my network settings are gone. I know the network is working because my other Macs and PC can access the network and internet. When I log on the eMac I get a message that I cannot log in at this time and to please contact my system administrator. Then he desktop appears etc etc etc. When I try to set the network settings I am told I cannot access the network. I connect via ethernet. My daughter swears it was fine a hour ago. Does anyone know what is up?
