"Network settings have be changed by another application" stuck in loops

I have the exact problem as others with Network System Preferences saying that the settings have been changed by another application. The message goes into a loop that can only be stopped with a Force Quit of the Preferences. I also have the Airport not connecting at start-up without choosing the Network Name from the Airport Pull down menu. I also think it may have started with the last Security upgrade and Java upgrade. I have used the airport utility to reconfig the base station. I discovered a system keychain with a password for the airport that my normal passwords would not open to show what it's password was. I have done many disk permissions and verifications. Any ideas? I would think if this is a Security update error, that Apple would be aware of it by now and post a repair. I have followed some threads on this issue but would rather wait for an Apple fix. There appears to be no way to contact Apple in customer support.

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.

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.

My Network settings are being changed by another program??

When i open up system preferences>network an alert window pops up to say "your network settings have been changed by another program"...so naturally i click the 'o.k' button to get rid of it, but it immediately pops up again.
So its impossible to make changes in my network settings because it'll keep popping up, meaning the only way to close system preferences is to force quit.
What could this other program be? could it be my ISP (virgin media) messing about with my settings?
so until i can fix my problem i cant even change any of the settings in the 'network' panel of 'system preferences'.......and you guys ideas to fix this would be appreciated!!

This recently happened to me. Go to System Prefs, Security. Click on Require Password to Unlock each secure system preference. That should do it. After you fix it, go in to security prefs again to uncheck it, or you will have to enter password each time you want to change any system prefs.

Trashed plists to fix the problem 'Your network settings have been changed

What is the easiest way to get back the plists that I trashed when following advice on how to fix :Your network settings have been changed.

Drag them out of the trash and put them back to the place from which you dragged them to the trash. If you emptied the the trash they are basically gone (unless you want to go to the excessive step of file recovery with $100 software and a spare empty drive). By the way, they are automatically created again with default settings when you invoke features that need them so it's not like you have a hole in your computer file collection.

Fixed "network settings have been changed" message but now can't network

As per suggestions, I deleted the files suggested, the message disappeared, and I reentered my network settings. But, now I can't connect to my laptop from my desktop. I can connect from my laptop to the desktop just fine, but when I try and connect in finder (and I tried connecting through network and through going to the laptop's ip address), it just spins for a while and then stops. Any notions?
The com.apple.nat.plist file didn't regenerate, but I put an old one in. Didn't seem to solve the problem.
Thanks!

Ok, now I've gone and put back the original files in the hd/library/preferences/systemconfiguration folder. I've got the annoying "your network settings have been changed" message in my network window, but I still can't network to my laptop.
Help?
FYI: The desktop is an old 2ghz x2 G5 running 10.4.11 and the laptop is a new MB unibody running 10.5.5

Look at this link. http://discussions.apple.com/thread.jspa?messageID=9372513
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.

Network settings changed by another application.

I select the Network option under system preferences.
I get a dialog box that says, "Your network settings have been changed by another application."
What does that mean?
This happens on my eMac and not my iMac.

Network Setting Changed by Another Application

Trying to access my Network Settings vie System preferences and keep repeatedly getting the alert *"Your network settings have been changed by another application"*. Cannot even get into my ethernet network settings as all I get is the above message.
I'm somewhat mystified?

Network Setting being changed by another application?

Hi,
Out of nowhere, I started to get this problem whenever I try to modify the settings on my Network Preferences. A prompt would pop up with the text "Your network settings have been changed by another application." and all I can do is click OK. After the OK is clicked, the same prompt would immediately reappear. This is on a 1.67Ghz Powerbook running OSX 10.4.11.
I'll try to link a picture to a screen grab.

Is this a virus?

woohoo found the answer from the Networking forum!

The page won,t open I get the settings were changed by another application message. It keeps appearing to I can't work with the diagnosics

The page won't open when I click on the firefox icon I go to system preferences for dianostics and "the settings have been changed by another application" I can't close that message to keep on working.

Are you referring to a wireless router, such as an Airport Express? If so, and you bought a different router, you will need to set up the new router according to their instructions. With my Netgear, I had to go to their online website (they should have the URL listed in the instructions) and set it up there because the software that comes with routers is not compatible with Macs.
If you're talking about something else, then please let me know - I've just never heard of an Airport modem.

"The file [name of file] may have been changed by another user since you last saved it." Issue affects both network and local files.

When a certain user saves a file in Excel 2010, she gets a message: "The file <name of file> may have been changed by another user since you last saved it." She can choose to save as another file or overwrite with her changes.
This just started happening a week or so ago. She was concerned that someone else was accessing her files, but we did several tests that opened, made a change and saved in a matter of seconds, and she still gets the message. It happens on
most files, but not all – both network and local.
We already tried the QFE_Saskatchewan registry fix. I also checked the file server for Services for Macintosh.

You may be confused by the error in Excel saying “another user”. Actually Excel cannot tell who (the real human) is editing the file. Based on my research the No.1 possibility of the error is KB2626998.
2626998 Connection to a network document is lost in the 2007 Office system or in Office 2010 after the computer resumes from standby
http://support.microsoft.com/kb/2626998
For Excel 2010, follow these steps:
a. Click Start , click Run , type regedit in the Open box, and then click OK .
b. Locate and then select the following registry subkey: HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Excel\Options
c. On the Edit menu, point to New , and then click Dword Value .
d. Type NetworkAvailableTimeInSeconds , and then press Enter.
e. Right-click NetworkAvailableTimeInSeconds , and then click Modify .
f. In the Value data box, click Decimal , type a number value, and then click OK .
Note This registry subkey sets the time, in seconds, that Excel waits for the network to resume. For example, if you type 15 for the number value, Excel waits 15 seconds for the network to resume. You might have to do some tests in your own environment to
determine an appropriate value. You may have to try multiple numbers.
g. Locate and then select the following registry subkey.
HKEY_CURRENT_USER\Software\Microsoft\office\14.0\common\Internet
h. Repeat step 2C through step 2F again. Reuse the same value that you used previously.
i. Exit Registry Editor.
Feel free to post back. Thanks.

Tony Chen

Alert: 'Network is changed by another application'

Opening 'systemconfiguration' I get the alert
'Network is changed by another application'
and I only can stop this by quitting 'systemconfiguration' instantly.
How can I fix this?

It was one of the last two Security Updates.

Until yesterday I was getting mail through my gmail acount on Apple Mail.. Today I am unable to recieve any mail No settings have been changed, using valid password etc. Any thoughts?

Until yesterday I was getting mail through my gmail acount on Apple Mail. I am now not getting any email. No settings have been changed, using a valid password. Any thoughts?

I found the following advice at: http://kb.mediatemple.net/questions/230/Common+issues+with+Apple+Mail#gs/not-rec eiving-email
Not receiving email
Once in a while, your Mail.app (sometimes referred to as "Apple Mail" or "Mac Mail"), stops receiving new mail. You may be able to verify that you are getting new mail via webmail, another email client or computer, or even via a mobile phone. When this happens, the fix is extraordinarily easy!
Here's how: From inside the Mail.app, click the Mailbox menu (see Figure 1):
Choose "take all accounts offline", and wait 10 seconds.
Choose "take all accounts online".
Figure 1: Follow these steps to refresh your Mail application.
You should begin seeing your new mail flow into your inbox.
It worked!

Autosave/Versions Issue - 'This file has been changed by another application'

In Keynote and Numbers, I often informed that 'The document xxx could not be saved. The file has been changed by another application.' Clicking 'Revert' simply results in 'xxx could not be reverted.' (The particular box below is actually from TextEdit)
This snapshot is from the informative link: http://krypted.com/mac-os-x/lions-versions-feature/
In the above-mentioned site, the author attributes this to 'changing hosts' and working on documents from different hosts. Indeed, I started the document at home and edited it at another location (where I connected to a different Wi-Fi network). Reading system.log from console, I see my host is actually my wireless network, rather than xxx's-MacBook Pro, as usual. Some examples of the errors (from system.log) are...
Aug 16 16:34:14 wireless-s1-no-xxx-xx-xxx sandboxd[1380] ([29]): revisiond(29) deny file-write-unlink /Users/xxx/Desktop/Presentation.key/1301543_55260978-1.tiff

Error Domain=GSLibraryErrorDomain Code=1 "The operation couldn’t be completed. (GSLibraryErrorDomain error 1.)" UserInfo=xxxxxxxx {}
I assume that the link is correct in that setting a new hostname is causing the problem. Unfortunately, I still have no idea how to fix it and I'm uneasy about the reliability of versions/autosave and/or my Time Machine backups.
Any advice, comments, or suggestions that you might have would be appreciated!

Hi Tony,
That's been reported here before, and it's happened to me. Maybe not exactly those words, but something similar, at least. I've always ignored the warning and have had no ill effects to date, that I am aware of. Nor have I ever figured out what the message may have been caused by.

I don't know what happened. All of a sudden, my settings have been changed, my homepage, and EVERYTHING. No matter how many times I go in and change them again, the SAME pages open up when I start FireFox and I am constantly being asked if I want Yahoo as my start page and default search engine. I click the box 'do not ask me again' and it comes up EVERY TIME. I change things like I don't want history remembered, and when I reload FireFox again, it's back to the way it was BEFORE. EVERY SINGLE TIME. I don't know why this is happening, or how to fix it. What do I do??

I do not want to download another virus program.. I do not believe it is a virus. I am running the full version of Norton 360 and it is doing a daily scan. I have Windows 7, 64 bit OS.
This is very irritating !! If I wanted Yahoo I would ask for it !
