Automatic Proxy Configuration URL doesn't work on some computers, but Manual proxy can work

It seems that the Automatic Proxy Configuration URL doesn't work, I use the command netstat -a, can't see the connection to proxy server, but manual proxy is ok, and I tested on some others computers, most of these computers can work normally with Automatic Proxy Configuration URL.
For the computer can't work normally with Automatic Proxy Configuration URL, I did below actions
1.Clear the cache
2.update the version of firefox
3.reinstall the firefox
4.use the safemode to run firefox
but unfortunately, still doesn't work.
Can some dear friends give me a big favor for this? Thanks a million in advance!

I have the same problem, just showed up recently - very fricking annoying!!

How do I troubleshoot installation/distribution of a LabVIEW .exe which processes data using Matlab when it works on some computers but not others?

I've been given the unenviable task of troubleshooting and installing/distributing software written by a former co-worker. I've modified the LabVIEW code and built an .exe file. I've successfully installed the Labview .exe file on several computers, but it won't work on some others. What's more baffling is that I installed it successfully on one computer, uninstalled it, and tried reinstalling it with no success. In fact, it's a new error (Dr. Watson for Windows NT application error). It doesn't help that I have different versions of LabVIEW and Matlab on the target computers. Some have LabVIEW 5.1, some
have 5.0, and some don't have it at all. Some have Matlab 5.2, some have 5.3 (R11) and some have 6.0 (R12). It's also not clear to me where the Matlab m files should be located. I'm not sure if it's a LabVIEW Runtime Engine problem, or if it's a Matlab problem. I've also wondered how LabVIEW and Matlab talk to each other. When LabVIEW calls Matlab, it seems that Matlab is running in the background. In other words, clicking on the Matlab Command Window and typing "whos" or any other command/variable doesn't work.

Flash working on some computers - but not others

Good afternoon,
We had a third party flash developer build out the flash
navigation and masthead videos for a client's web site and although
it works fine on my computer (and on the developer's computer), it
does not work on any of the client's computers or my partner's
computers.
Here is the web site in question:
www.quigleysimpson.com/index2.html
According to the client and to my partner, the video cuts out
after a second or two, and some of the navigation links are coming
up 'not found' (e.g. the Multi-Cultural link in the top
navigation).
Upgrading to the latest version of Flash Player was the first
thing we did, and the problem still exists. I can't for the life of
me figure out why.
Any help would be most appreciated.
Cheers,
Cynthia

I understand that neither method did the repairs you are seeking. My post was a side-note information update for you and others who read these posts, that we haven't had to boot from the install DVD to do a Permissions Repair since Tiger (I think)or maybe even Panther (doesn't matter when the requirement was dropped anyway), and that you can actually set some permissions wrong by using the boot DVD because of changes in the OS since it was installed.
For your problem I recommend creating a new temporary Admin user account and seeing if the problem continues in the new account. If it does, then the problem is in the OS, which can be re-installed over the top of your existing installation (without affecting your files in your user accounts). If the problem goes away, then it could be incompatible or corrupted preference files or other incompatible programs in the user account causing the problems. Right now you haven't isolated the problem to either possibility.

Lion Server network accounts not working on some computers.

Hello all -
I'm currently having an issue with network accounts working on some Macs but not others. I have a Mac Mini and a MacBook Pro. The Mac Mini works fine and I can login and sync my network account with the server just fine. However, I cannot connect to it from my MBP.
When I try and connect I get an error that says "You are unable to log in to the user account "xxxx" at this time. Logging in to the account failed because an error occurred."
If I login through console (by typing in ">console" in the username field) I get an error that says the user does not have a home directory...
I have searched numourous other forums but I have not found a solution that seems to solve this problem. I have unbound and re-bound my client to the open directory and I have restarted file sharing. Neither has solved the problem. I have a feeling the issue originates somewhere on the MBP since I can log in to the Mac Mini without any problems.
Anymore suggestions?

Thanks for your suggestion, SolidWood. Unfortunately it didn't help.
After a 90 minute phone call with AppleCare, this issue has finally been resolved. Here is what the solution was. Turns out it was pretty simple but it took a while to find it.
First we created a test user and left the home folder set to Local Only in the Server App. I was successfully able to login with the test user on both clients but since there were no mobility preferences set, it was pretty basic.
Then, we removed the Users sharepoint from file sharing, turned off file sharing to disconnect any users, and restarted the server. Then we created a new folder on the Server HD with a random name. We chose Darron. We created a new sharepoint in file sharing (with it still turned off), and shared the new folder called Darron. Double click on the sharepoint and scroll to the bottom and check the box that says "Make available for home directories over AFP". Then we restarted file sharing.
Then we opened Workgroup Manager, clicked on the problem user in the left sidebar, clicked on the Home option at the top, and there were three things listed:
     (None)
     afp://servername.com/Users
     afp://servername.com/Darron
Then we removed the Darron sharepoint from file sharing, and found that it was still listed as a home directory under the problem user.
This was the root of the problem. The system didn't know which path to use as the home directory.
Sooooo...
In the server app, we opened the Directory Utility (Tools in the menubar, Directory Utility). Clicked on Directory Editor. Authenticate to the directory using the diradmin login. Changed view settings to match this below:
In the left column, there were two paths listed for home mounts. We deleted both of them, saved changes, and closed directory editor.
Then, we restarted workgroup manager and both paths had been deleted from the users home listings. This was begining to solve the problem.
In the Server App, we recreated the users sharepoint, made it available for home directories, and restarted file sharing and workgroup manager. Now only one path is listed for the home folder for all the users.
This solved my problem of not being able to login on the MBP. The system synced the home folder and all was well. On the Mac Mini, I had to delete the problem account, un-bind from the network server, re-bind, and recreate the account. Now both clients are sycning perfectly and all is well.
Thank God I bought AppleCare! Thanks to everyone else for their help and suggestions.
As a recap, the problem of not being able to login to the MacBook Pro was caused by having multiple paths to the multiple home folders. These rogue paths were added somewhere in the troubleshooting process to try and recreate the home directories before I called AppleCare. To solve this, we had to remove the directory listings from accounts using Directory Editor, remove and recreate the users sharepoint in file sharing. The syncing problem on the Mac Mini was also created when multiple paths were introduced. The system didn't know which files to use.

You can not merge accounts.
Apps are tied to the Apple ID used to download them, you can not transfer them.

I had the same problem- go to Utilities, General, Use Side Switch To, and change it from Mute to Lock Rotation- this solved the problem for me.
Good luck!

Have you tried resetting your iPad?
Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds).
No data will be lost.

I have the macBookPro and the problem is the mouse pad does not work I tried everything but still does not work what should i do ?

I have the macBookPro and the problem is the mouse pad does not work I tried everything but still does not work what should i do ?
so i'm using the usb mouse

I want to clarify the issue.
The issue is with the MBP trackpad, and it works fine with an attached USB mouse.
With some ingenuity, you might be able to fix this yourself, but I suggest visiting your local Apple Store/Genius Bar. Some have fixed this issue and have posted their results online, but the Apple Store should be your first destination.
Post here with your results!!

How to roll out proxy configuration url?

I would like to roll out the "proxy auto-configuration url" setting on our entire network, via login script.
With other Browsers it was easy enough to roll-out a *.reg file adjusting the browsers registry section on every client, but I can't find the pendant for firefox.
I read in some forums, that these settings are stored in prefs.js, but couldn't work out a way to distribute that over our network as easy as the .reg files.

A possibility is to use a mozilla.cfg file in the Firefox program folder to set new default values for prefs or lock the prefs to specific 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");
pref("general.config.obscure_value", 0); // use this to disable the byte-shift
See:
* http://kb.mozillazine.org/Locking_preferences
You can use these functions in mozilla.cfg:
defaultPref(); // set new default value
pref(); // set pref, but allow changes in current session
lockPref(); // lock pref, disallow changes

DNS not working for some computers

We have a SRP521W router and is set up with one SSID for wireless. In our office all the computers (5) can connect but only some may get on the internet. I have a laptop I am testing with and it will not connect, wired or wireless.
I found an article relating to flushing DNS, tried that, no luck.
I found another that said I should try setting my DNS to 208.67.222.222 and this worked, internet works fine.
I tried rebooting the DSL modem and router, tried many different things but am not a networking guru so I am just not sure why the DNS is not working for one computer but works for another, connected to same LAN or SSID.
Thanks,
Brad

Though what Don posted is one way to accomplish it, I never add anything to my DNS and it works fine. Windows DNS, in a default installation, will automatically forward to the root (.com, .edu, .gov, etc.). So I always just point my workstations
to my Domain Controller as their DNS and everything works just fine without any additional configuration.
Guess I'm one of those who won't even trust Google for sharing a DNS, particularly when I have never needed to set up any forwarders.

Airport extreme working on some devices but not others

All of a sudden airport extreme has stopped working on some of our devices. within our family we have an old macbook pro running tiger, a 2nd gen macbook air running snow leopord, a black macbook running lion, a mac mini running lion, two iphone 4s and an iphone 3g. the wireless only works on the two computers running lion. nobody has changed any of the settings on the airport extreme. it is running the latest version and has been working fine up until a couple of days ago. i have reset the modem and router several times each but nothing has helped. when we try to connect the iphones to the wireless they say unable to join network and the computers running snow leopord or older say there was a problem connecting to the network or something similar to that. any help would be appreciated!

I know that you have reset both the modem and AirPort already, but I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
(OPTIONAL, but recommended) While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Power-up the modem; wait at least 10-15 minutes.
Power-up the base station; wait at least 5-10 minutes.
Power-up your computer(s).
In this basic configuration, computers connected to the base station, either by wire or wireless (as appropriate for the base station type), should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options.
