Hello Mike,

If just checking "Require password to unlock each secure system preference" in System Preferences > Security - has permanently fixed your problem, that is great, don't do anything else ;-)

If it hasn't fixed your problem you can delete these files .... BUT, before you do ... write down all your Network Settings as you will have to reinsert the data after deleting these files.

Go to Library/Preferences/SystemConfiguration and delete the following (suggest make copies to the desktop first if in doubt)
First drag them to the desktop to make COPIES.
Then drag the ORIGINALS to the trash. You'll be asked to authenticate this action, so just type in your password and you'll be able to trash the files.

com.apple.airport.preferences.plist
NetworkInterfaces.plist
preferences.plist
com.apple.nat.plist

All these files will regenerate as necessary when the associated system features are accessed. If you're using Airport or Internet Sharing you'll have to re-establish the appropriate settings, because these will have been lost when the preferences files are removed.

Cheers,
Ronni

I'm not sure what did it but, after a long bout of insomnia, my G5 Dual 2.0 running OSX 10.4.11 is now automatically going to sleep.

Since it was discussed here we have had a security update and an update to i-Tunes. I have also swapped some corrupt memory that wasn't registering in the system with some that is working.

I'd be interested to hear if anyone else who had the problem has had it resolved.

Another interesting item is that my network preference pane comes up with a drop-down window that states "Your network settings have been changed by another application." After clicking OK the window just keeps reappearing, making it tricky to exit preferences without a Force-Quit or some fast work with the return key and the mouse.

The general consensus is that the latest security update led to this behaviour. Again, I'd be interested to know if anyone here has the same problem.

BTW, a solution is to activate the "Require password to unlock each secure system preference" checkbox within the Security preference pane.

Cheers
