System preferences -- Network settings changed

When I go to System Preferences/Network, I get a pop-up message saying, "Your network settings have been changed by another application." I can't get rid of the pop-up and can't close the window My only alternative is to force quit.
Does anyone have any ideas as to what caused this and/or how to get rid of the pop-up message? I would be very grateful for any help.
The expert at my Mac store says he is familiar with the problem but has no answer for it.

A Fix for "Your network preferences have been changed by another application" Error
In the Library/Preferences/SystemConfiguration/ folder delete the following:
com.apple.airport.preferences.plist
NetworkInterfaces.plist
preferences.plist
com.apple.nat.plist
You will have to re-configure all your network settings since deleting these files will cause them to be returned to defaults.

System Preferences Network Settings

Using a Power PC G4 with OS X 10.4.11 and Security update 2009-001.
In System Preferences, as soon as I click on "Network", I get a pop-up window stating: "Your Network Settings have been changed by another application." After I click the blue OK button, the message immediately reappears, over and over. Only way to exit is to FORCE QUIT.
Internet and email are working fine.
Is this a virus??? Any ideas???

G4 10.4.11 System Preference Network settings lock up.

Having searched first, I found my problem:
"When I open System Preferences and then open Network, a box drops down that says "Your network settings have been changed by another application." If I click the blue OK button, the box disappears momentarily but continually reopens, thereby not allowing me to quit System. "
But no answers.
This stared after I attempted to add a windows machine,98, to our home network on a belkin 4 port router, via ethernet. This operation failed for unknown reasons. At one point I entered the router IP address in the Windows system and may have entered it wrong. I have since disconnected the windows machine from the network and I still have the lockup in System Preferences. My coonection still works though as I am posting from the affected G4.

I did BDAqua's suggestion
To stop the pop-up, Go to System Preferences: Security. Check the box next to "Require password to unlock each secure system preference." Then lock Security.

Problem with internet. When i open System preferences, Network, message drops down: 'your network settings have been changed by another application'. I click OK, but it drops a message again and again, preventing me to do anything about the setting.

Use Software Update to update your OS to last version of Tiger. Install all the other updates that goes along w/it.

When I go to System Preferences Network "Click the lock to make changes",... it ALWAYS UNLOCKED. That is even if I have locked it before last shutdown. Should it not stay locked until I unlock it again as administrator?

From the menu bar, select
 ▹ System Preferences... ▹ Security & Privacy ▹ General
If there's a closed padlock icon in the lower left corner of the preference pane, click it and authenticate to unlock the settings. Enter your login password when prompted.
Click the Advanced button and check the box marked Require an administrator password to access locked preferences in the sheet that drops down. Then click OK.

Safari was very slow in opening up Google sites. I found a discussion thread that suggested changing the "Configure IPv6" setting to "Off" in the System Preferences, Network, Advanced, TCP/IP section. That seems to work well. Are there any risks?

Nope. You can always reverse that if you choose.

How can I disable the Edit- Preferences- Network- Settings- Noproxy option

I want to disable the Edit->Preferences->Network->Settings->Noproxy option
Every user user should access internet only via proxy settings what i should do for that and also should not be allowed to change the option

Note that on Linux, the default is to use the "Use the system proxy settings" setting for the connection.
You can look at these prefs to lock:
*http://kb.mozillazine.org/network.proxy.type
*http://kb.mozillazine.org/network.proxy.%28protocol%29
*http://kb.mozillazine.org/network.proxy.%28protocol%29_port
Use a mozilla.cfg file in the Firefox program folder to lock prefs or specify new (default) values.
Place a file local-settings.js in the defaults\pref folder where you also find the file channel-prefs.js to specify using mozilla.cfg.
pref("general.config.filename", "mozilla.cfg");
These functions can be used in the mozilla.cfg file:
defaultPref(); // set new default value
pref(); // set pref, but allow changes in current session
lockPref(); // lock pref, disallow changes

Issues with System Preferences Network

When opening System Preferences > Network on my Powerbook G4 running OSX 10.4.11, I get stuck in a loop.
I get the pop-up alert "Your network settings have been changed by another application." When I click ok, it pops up again.
How might I resolve this?

1.) Apple-Menu -> Force Quit and shutdown System Preferences
2.) System preferences -> security -> "Require a password to unlock each System Preferences pane" Check it.
3.) Launch System Preferences -> Network and everything should be fine

Subsequent device(speaker) detection over USB, results in new interfaces in the list(System Preferences- Network)

Hi,
There is a problem when device(speaker) is unplugged and plugged in Mac OS version 10.7.5
Every time unplug and plug the device over USB and re-plug, new interface is added in the list System Preferences->Network.
For example, if the device interface name is device20, when the device is plugged first time, system shows "device20" in the detected device list i..e in System Preferences->Network. But next time when unplugged and plug again the device name gets changed(device number gets incremented), i.e. "device21" will be displayed. So if repeatedly unplugged and plugged, the device number gets incremented everytime and added to the list as device22, device23,....etc. The list will grow with many entries if we repeatedly unplug and plug the device.
I am not sure why the system is behaving so. You help/support will be highly appreciated.
Thanks in advance.

Lock icon opens automatically on System Preferences Network window

The settings lock icon often is unlocked when I open the System Preferences > Network window.
I can click the lock icon and it locks without being prompted for a password.
This generally occurs right after logon.
How do I fix this problem?
Thanks.

1. Delete this file: "/Library/Preferences/SystemConfiguration/NetworkInterfaces.plist" and reboot the computer.
2. Yes, or rename a current location to "Automatic"
3. No. You can't.
4. See #1

System Preferences: Network Error

Hi folks.
Just got my Touch today. Very well done.
On my G5 (10.4.11), in System Preferences:Network, the little window keeps popping down, indicating something has changed my network. Over and over and over and over again. This started happening after I installed my Touch.
I can't make it stop. Driving me crazy, and I have to force quit system preferences.
Any idea how I take care of this? Console says nothing.
Cheers

I have saved this solution from BobP1776 here from the forums - but can't identify it right now - have you tried this?
""I now have a procedure which appears to fix it, but I'm not sure it is the minimal procedure. Folks who try this may find they can eliminate one or more steps and still get the good result.
Symptom: Airport won't reconnect to a known network, and turning Airport off and then back on again does NOT make the connection to the known network happen.
Solution: Do the following steps in order
Turn off Airport
Go to System Preferences / Network. Click on the lock and authenticate with an administrator password if necessary.
Select Airport in the column on the left.
CLEAR the check box for "Ask to join new networks"
Click on Advanced.
CLEAR the check box for "Remember any network this computer has joined"
Click on the known network in the list if it is already in there. Click on "-" to delete it from the list.
Click OK to exit the Advanced pane. Click Apply in the main Network pane to make these changes take effect.
Now turn on Airport. The network will not be selected of course since it is no longer "known".
Click on the Airport indicator in the Menu Bar to open the drop down menu.
Click on "Join Other Network". Do this EVEN IF the network you wish to join is not "closed, i.e., is already showing in the list.
In the dialogue panel, enter the name of the network, the type of password, and the password itself. Also VERY IMPORTANT click to check the box to "Remember This Network". Connection should now be established.
Return to the System Preferences / Network pane. Click on Advanced again and confirm that this network is once again in the list. Click on Cancel to return back to the main Network pane without making any changes.
Click on Assist Me. Click on Diagnostics.
Even though the early test will likely say that everything is fine, click Continue to go through the rest of the tests ANYWAY. The Airport network you are connected to should show up in the list when you are asked to choose which network to join. Click on it. If it is not in the list for some reason, select Other and type in its name.
You should now be presented with a panel asking you to AGAIN enter the password for this network. Do so. And VERY IMPORTANT click to check the box to remember this password in the keychain.
Diagnostics should now complete and tell you everything is fine.
At this point, your account should now reliably and automatically rejoin this network either on restart or on waking from sleep. If the system ever misses the network on restart or waking due to weak signal or some transmission timing glitch on startup, simply turning Airport off and back on again (using the indicator in the menu bar) should suffice to get you connected again. This procedure for remembering the network should work with both open (visible names) and closed (non-visible names) networks.
Presumably there is something going on in this procedure that causes the key bits of information to be saved in the right places.
It SHOULD be easier than this of course. But at least this seems to work until Apple sorts this out.
Please note that this appears to be a PER-ACCOUNT problem. I.e., you will likely need to fix this in EACH account that's having trouble remembering the network and re-connecting automatically.

AirPort does not show under System Preferences Network Show

Hello,
I am having problems with my AirPort Express. It is listed in AirPort Admin Utility (with an IP Address), but does not show up under System Preferences > Network > Show.
How can I get the AirPort recognized?
Thanks,
Fidelio

In System under "Network" it shows "AirPort Card" with "No information found"
Your Mac does not have a wireless card installed or it is not working.
However, I would like to set up a shared printer and instructions I have for this say that I need to get the IP address of AirPort under System Preferences > Network > Show > AirPort.
That information should have nothing to do with a printer since the information there relates to your Mac... not to the AirPort Express (AX).

System Preference Icons have changed

Hi
The Speech and Startup disc Icons in my system preferences pane have changed to something like a switch.
The other accounts on the same mac have no such problems.
Any suggestions?
THanks
MacBook Pro Mac OS X (10.4.5)

Choose Go to Folder from the Finder's Go menu and enter ~/Library/Caches/ as the folder's path. Once this folder has appeared, locate the com.apple.preferencepanes.cache item and drag it to the desktop. Open System Preferences again. Mac OS X 10.4 does not create or use any items starting with LS or .LS in the ~/Library/Preferences/ folder.

Every time I switch on my iMac I have to go through System Preferences, network, to access the internet. It runs Mountain Lion OS. However my Macbook Pro which still runs Snow Leopard connects to the internet OK, from thew same wireless router. This sta

Every time I turn my iMac on it will not connect to the internet until I open System Preferences / network / Assist me. that reports that my internet access appears to be OK, and hey presto my web home page appears, and everything if ok. The same happens if I have opened Mail, nothing until I've gone through the above proceedure.
This has been happening for a week.
The iMac uses Mountain Lion.
I have no such difficulty with my Macbook Pro which runs Snow Leopard.
I have deleted the safari caches and logs, to no avail.
Any suggestions would be greatly appreciated.

Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work.
Isolating an issue by using another user account
If the problem is still there, try booting into the Safe Mode. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the grey Apple icon and a progress bar appear. The boot up is significantly slower than normal.
