After working to configure my PowerBook 17" (Mac OS X 10.2.6) with all of the network locations that I might need, everything disappeared. After getting over the initial panic, I found the solution.
The symptom: My network locations are gone! Things seem to be so messed up that I can't even reconfigure my network settings.
The result: Panic! I poked around the system looking for a preference file that got corrupt. Apparently there are no preference files in the home/library folder for the network configuration. I then tried to reapply the 10.2.6 combined updated. No joy. I was able to find a post on the macosxhints' forums that lead me to the answer. A user asked if there was a way to backup their network configuration settings. The answer was yes.
This little gem is hidden in the following location: /var -> db -> SystemConfiguration. Upon inspection, nothing looked wrong. So, I tried to open the file in pico. Strange, why would it want to create a new file? So, I compared the folder listing to that of my iMac which didn't have this problem. This was the key. It appears that the permissions on this file were missing the Read property. Once I added the Read permission, everything was fine.
Hindsight being 20/20, running Disk Utility to Repair Permissions may have corrected this problem without all of my legwork.
