Can't login to iCloud, App Store, iMessage and Facetime

[emiellr]

Hi all,
I installed mountain lion a few days ago, and i finally got it (almost) running with no trouble, except for the app store and such. I have tried some methods like removing chameleon boot.plist, removing NetworkInterfaces.plist, checking if en0 was set to that...
said short: could somebody help me to make this work?
I have a dell 760 Tower with onboard ethernet. I think I know whats wrong: IOBuiltIn is set to false and the pc says its a pci card, which, as I sais, isn't.

could somebody help?
best regards,
Emiel

On the admin user iCloud, App Store, iMessage and FaceTime work. But on other users not. This is due to a problem with the network interfaces. Deleting Library/Preferences/SystemConfiguration/NetworkInterfaces.plist and restarting afterwards solves it.

Thank you! That did the trick.
