Network error - 2009/08/26 07:01I have a friend that has a Cube, she is having a network error, I can not remember which Plist to trash, thank you in advance! Here is her message to me:
"I went to go into my network under system preferences - I immediately get a message that "Your networks settings have been changed by another application." when I click on "okay" the message goes away but immediately pops right back - no way to get away from it. the only way to get out of that is to "force quit" on the system preferences - what is going on?? I have run disk warrior and disk utility with no information."

Re:Network error - 2009/09/05 23:26Hi Randy here. I was having the same problem so I did some research and this is what I found, and it did solve my problem.
The issue is with a security patch Apple released. They changed the way PPP and PPPoE passwords are maintained on your system. To fix it you first need to make that lame "Your network settings have been changed by another application" dialog stop popping up. To do this open "System Preferences" and go to "Security". Tick "Require password to unlock each secure system preference". Now click "show all" at the top. I had to quit "System Preferences" to make the change take effect. Open "System Preferences" again and choose "Network". You will probably get the annoying pop up once, but this time when you click "OK" it won't loop. Notice that the padlock in the bottom left corner is now locked. Click it to unlock. Enter your password (assuming you are the administrator on the Mac). Now click back on the show all button. The Mac will think you made a change and ask if you want to " Apply configuration changes" click "Apply". Once it saves the changes your problem should be fixed. You can go back to the "Security" pane and untick the option you enabled earlier.
There is one catch to this fix that had me stumped for a good while. If you have ever used an external modem on your system there could be PPP settings that you can't get to without having the modem attached. What a pain! I could see "External Modem" in the port configurations, but it was grayed out and I couldn't make any changes. The only way to edit the PPP password was to find a modem and plug it in. "External Modem" became an available option and I could now edit the settings. Such a stupid problem! Hope that nugget helps anyone stuck in a similar situation.
