AppleMobileDeviceService.exe stays at high CPU – reason is LSPs

October 15, 2011 – 9:39 pm

[UPDATE 11/21/2011] Apple has a very good page explaining how to work around this problem, albeit while not acknowledging that it is their problem.

Here is the original post:

My Intel Core2Duo Windows 7 64-bit computer started having this problem with the AppleMobileDeviceService.exe taking 50% of the CPU usage continuously, whether iTunes was open or not. Some may see 100% of the CPU in use.

Apple’s support recommended a painful “uninstall everything in this exact order and reinstall everything.” I generally hate that approach because they just aren’t trying to figure out what’s wrong, plus many users were saying it just came back immediately or a week later.

This sounded like a more reasonable solution (downgrading the Apple Application Support from 2.0.1 to 1.5.2), but it made me nervous that it might affect functionality with the iPhone 4S or iPad2. I assume that when Apple included this update is when the problem started for me.

Then, I found this blog that recommended a “netsh winsock reset” which sounds like a true fix to me. I did that and my Bsecure/Bsafe CloudCare (internet filtering software) popped up a notice that it had repaired itself. After restarting, the problem still persisted. I then uninstalled Bsecure CloudCare and the problem was gone! [Clarification: I do not recommend the "netsh winsock reset" because of the risk to messing up the computer!]

On that blog the author says, “Apparently the Windows TCP/IP stack can get corrupted and this will reset the Winsock Catalog to its default state – i.e. one that works properly.” I think he is correct, except for the “corrupted” part. According to Wikipedia, “a Layered Service Provider is a DLL that uses Winsock APIs to insert itself into the TCP/IP protocol stack.” Bsecure CloudCare and other webfiltering solutions use LSPs to do the filtering. Some malware/adware in the past insert LSPs, as well. I bet that there are a heck of a lot of computer users out there with a non-standard TCP/IP protocol stack that are suffering badly from this software bug of Apple’s making.

I’m not 100% certain on this, but with my own experience and seeing how doing the “netsh winsock reset” fixes the problem, it makes sense.

If you are thinking of trying the “netsh winsock reset,” be aware that it could be fixing a problem, or creating a worse problem than Apple’s bug.

[UPDATE 10/17/11] Based on Matt McLaughlin’s comment, I’m feeling more confident about my theory. He looked at his “Winsock Providers” tab in Sysinternals’s Autoruns. Check it out to see if there is anything there if you have this problem. I will not recommend what to do about it.

[UPDATE 11/21/11] SO, it looks like Apple has endorsed my conclusion about what it causing this problem (link to Apple’s support document about this very problem). And their solution to this problem: REMOVE ANY SOFTWARE THAT USES LSPs. Yep, these vendors use LSPs for 10 years or more and Apple’s software has a bug that causes our computers to malfunction and we must remove the other vendors’ software, not get an update from Apple to fix the bug…

[UPDATE 12/18/11] Here is a list of software that is rendered unusable and needs to be removed because of this problem:

  • Bsecure CloudCare/Bsafe
  • CA Antivirus Suite (Computer Associates, free with Time Warner cable)
  • PC Tools Antivirus (not the newest version)
  • Alienware’s Xeno Power Suite
  • Kaseya – remote management
  • Integard from Race River – filtering
  • SafeEyes – filtering
  • Filternet – filtering
  • Apple’s list:
    • Bigfoot Networks
    • ByteMobile, Inc.
    • Covenant Eyes
    • SpeedBit Video Accelerator
    • VMWare

[UPDATE 1/21/2012] Bsecure has somehow released a “fix” that allows CloudCare and iTunes to both work fine together. Here are their instructions:

  1. In order to run the iTunes fix we will need to determine if you are on a 32 bit or 64 bit system.  You can do this here:
    http://windows.microsoft.com/en-US/windows7/find-out-32-or-64-bit
  2. Now click on the link for your system
    32 bit computers – CLICK HERE
    64 bit computers – CLICK HERE
  3. Run itunesfix32.exe OR itunesfix64.exe
  4. If you are using Mozilla Firefox, it is possible that you may have to ‘download’ the file first, and then double click on it in the downloads list.
    Note:
    Internet explorer may require you to click keep, and then run.
  5. You will know the fix has finished when you see a black box appear on your screen for a moment, and then disappears.
  6. After this happens, reboot your computer one last time.

iTunes store should now work properly & the mobile device service will no longer conflict.

  3. I’ve struggled with this after installing 10.5 on four different systems. I tried the uninstall/reinstall. No difference. I tried the resetting winsock. No difference. But it’s winsock related! Using Sysinternals AutoRuns and found several winsock catalog entries that were pointing to a invalid filepath. I removed the bad entries using AutoRuns. Rebooted and voila…ITunes without a CPU hogging AppleMobileDeviceService!

    By Matt McLaughlin on Oct 17, 2011

  4. Here is a follow up from Matt:

    I use a remote management/monitoring product called Kaseya. Their agent created the winsock entries. I think it was for a feature I used in the past. I don’t their agent software properly cleaned up after this feature was disabled. But others could also have the “bad” entries in their winsock catalogs which may cause the issue.

  5. i’ve been having the same problem on a Windows XP machine for weeks – since I updgraded to iTunes 10.5. Did the same install on another PC at work with same config, but no issue there. I went through the uninstall process in the sequence that has been suggested (e.g., iTunes, then Quicktime, etc., etc.). Then reinstalled iTunes fresh when all Apple software had been removed. No fix.

    Sounds like you guys are onto the problem, but have you got a solution for layman, as I don’t speak your language? L-)

    Only thing I have found that “works” is to disapple the Apple Mobile Devices service, but of course, while that stops it from using 99% of the CPU, it also stops iTunes from synching up to my iPhone.

    Thanks in advance to anyone who can explain the actual fix to me like I am a sixth grader!

    By Brad K on Oct 18, 2011

  6. Sorry, I know this is complicated! Apple is the only one that can “fix” this, not you. I “fixed” it by removed my web filtering software, which I’m doing temporarily, assuming Apple will fix this. I’m afraid to give steps on how to “fix” it because it might destroy your computer’s ability to get on the internet.

    By brmorris on Oct 19, 2011

  7. I also use Bsecure CloudCare filtering software, and I just started having this same problem with AppleMobileDeviceService.exe as well as two other related Apple programs. The three of them were each taking 25% of my CPU and preventing me from backing up. I’ve been running iOS 4.3.5 for a while and was trying to do a backup and sync today before installing iOS 5 when this happened. I also got error messages saying the backup could not be saved to my computer. Frustrating! I tried installing iOS5 anyway, but that wouldn’t work either. Kept timing out on a fast 3MB connection. More frustration.

    By Todd Nelson on Oct 20, 2011

  8. I have checked numerous forums for a solution to this problem and stumbled across something. I saw a couple of recommendations to disable your firewall and one to reset your winsock catalog, so I diag’d my TCP/IP stack and once I reset it, i could connect to the itunes store (i was getting system hang at “accessing itunes store”) and my cpu utilization for applemobiledevice was restored to normal. do these two commands at a cmd prompt. (you’ll need to “run as admin” in vista and win7)

    netsh winsock reset
    netsh int ip reset c:\logfile.txt

    and then reboot

    this won’t change any of your IP settings and should fix your problem. i had this issue on two separate dell inspiron 6400′s and it fixed them. good luck

    By Steve on Oct 21, 2011

  9. Guys, thanks for the fix! I’ve been struggling with this, and done all the uninstall/reinstall steps, but was still locked up. I ran the above two commands, rebooted, and everything works great! I really appreciate you all sharing your solution.

    By Mark on Oct 21, 2011

  10. Integard from Race River has the same conflict as other Internet filtering software. I raised a case with them and Race River have been able to replciate the problem and are working on a solution.

    By Nix on Oct 23, 2011

  11. Thanks for the post. I WAS having the same issue after upgrading iTunes. Unfortunately I did try re-installing itunes prior to find this blog. The re-install didn’t fix it but resetting the winsock and restarting my system fixed the CPU from getting pegged out by the two apple services.

    By John F. on Oct 24, 2011

  12. brmorris mentioned that he has Kaseya on his machine as his RMM software. There is an option in the kaseya management console on the audit tab to disable the network driver that Kaseya uses. This driver uses certain hooks into winsock. We didn’t find any invalid paths using autoruns. With further troubleshooting we discovered that disabling the driver has resolved the issue for us.

    By Joshua J. on Oct 24, 2011

  13. The winsock reset did the trick! I had uninstalled and reinstalled three times to no avail and was at wits end. Thank you so much, Steve, for the magical posting. A non-technical person such as myself would never have figured this out unaided.

    By Tricia G on Oct 24, 2011

  14. Solved my problem also!! I ditto Tricia G’s comments. Thanks Steve! It worked. I’ve spent a day and a half working on this issue. Itunes and AMDS are using less than 5% of CPU now on average.

    By JohnR on Oct 24, 2011

  15. Windows XP…….”at a cmd prompt…

    netsh winsock reset
    netsh int ip reset c:\logfile.txt

    and then reboot”

    WORKED!!!

    By Bobby on Oct 25, 2011

  16. From what I understand you have to do the “netsh winsock reset” every time you start your computer right?

    By dave on Oct 25, 2011

  17. No, it should be one time and done. In my case I had filtering software that would “fix” itself by reinstalling the LSP after that comment removed it. That could be happening to you. Keep in mind, this is Apple’s bug – they should be fixing their software, not us.

    By brmorris on Oct 25, 2011

  18. This is terrible!
    When I upgraded to 10.4 the unistall/reinstall sequence worked for me. I had to upgrade to 10.5 for the new 4S and the unistall did NOT work.
    And this is a work laptop that I don’t have administrator rights to, so I can’t run the winsock fix either! I’m stuck!
    I can’t understand how Apple hasn’t fixed this in the months since it came out! I’m disappointed!
    Not happy right now!

    By cgomezmoreno on Oct 25, 2011

  19. netsh commands worked for me on XP as well.

    By Sluggo on Oct 27, 2011

  20. I just spoke with the tech support at bSecure… they are aware of the issue, and working on it. The very nice lady that answered the phone on the first ring was much nicer than the Apple Tech that I held for 45 minutes for this morning… she advised that the ONLY way to access iTunes 10.5 is to completely uninstall the filtering software. There is no way to enter an exception into bSecure, to use a different (administrator) account on the computer, etc. The ONLY option is an uninstall. By the way, it is not just bSecure, almost all content filters have the problem.

    By scmanley on Oct 27, 2011

  21. Thanks Steve this seemed to work … i’d tried the uninstall / reinstall procedure as well as the winsock reset with no luck, but the winsock / ip reset combo seems to have worked, at least for now. Many thanks.

    >< Spoke too soon; on restart the problem is back.

    By TimS on Oct 27, 2011

  22. Got this form the thread on the link.

    It seems a better fix as the service still starts but without the high CPU usage.

    Quoted from “happyfrosh”:

    “I had luck with the following:

    Start… Run

    services.msc

    select Apple Mobile Device Service

    right click to open Properties

    change from startupType automatic to startupType automatic (delayed)

    reboot”

    By jo on Oct 28, 2011

  23. https://discussions.apple.com/thread/3185699?start=105&tstart=0

    Eventhough it fix the HIGH CPU usage. I still couldn’t open the Itunes store. I’ll stick with this until Apple has an actual fix. =|

    By jo on Oct 28, 2011

  24. Brian,

    I just want to make sure I’ve got this straight, the problem will persist as long as content filtering software is on my computer? That at the present time, there’s no way for me to keep the filtering software and not have applemobiledeviceservice.exe hang at 50% of my cpu?

    By thelastchinaman on Oct 28, 2011

  25. To all that I’ve been able to figure out, yes, that’s true. Apple needs to fix this!!

    The other new idea I haven’t tried is in the comment by “jo” above. Try that.

  26. Windows XP…….”at a cmd prompt…

    netsh winsock reset
    netsh int ip reset c:\logfile.txt

    and then reboot”

    WORKED!!!

    By Doug on Oct 29, 2011

  27. Brian,
    Sorry to be dim but exactly what do i do with the netsch winsock data above? I’ve no idea what “at a cmd prompt means, can you help a simpleton please?
    Thanks.

    By Tony on Oct 30, 2011

  28. Ps i’m using windows xp.
    Thanks again.

    By Tony on Oct 30, 2011

  29. I had the problem with BSecure as well. You have to remove BSecure from your individual PCs, but you have the option to put “Whole Home Filtering” on your router and that filters everything on your network. This works better for me anyways since it filters all network devices. See the BSecure website for details.

    By Marco on Oct 31, 2011

  31. Mark,

    The downside is that you lose all the advanced features of having CloudCare on the computer..

    By brmorris on Oct 31, 2011

  32. Tony,

    No need to be embarrassed — remember I’m not recommending doing this —

    “at a cmd prompt” = Start menu > Run > type “cmd” > OK — now you get a DOS window, which is a cmd prompt!

    By brmorris on Oct 31, 2011

  33. I’m afraid of the winstack and IP reset. what exactly do they do? How can you save a backup of these, so that they can be easily restored if this screws things up?

    By rnail on Oct 31, 2011

  34. rnail,

    I don’t blame you, this is why I’m not recommending it, I’m hoping Apple fixes it, but I don’t even know if they are acknowledging the problem yet. I don’t know of a good way to restore, other than maybe a Windows System Restore to a prior date.

    By ratman on Nov 3, 2011

  36. Confirming that the “solution” is to simply uninstall bsecure. iTunes 10.5 worked fine, sync’d and updated my phone to IOS5. Then I reinstalled bsecure.

    By cgamble on Nov 4, 2011

  37. Thanks Brian.
    One last thing, do I need to do it twice, once for each cmd?
    Thanks for being understanding when i’m not!

    By Tony on Nov 7, 2011

  38. I just want to put out there that the “netsh” fix worked for me. Thank you so much for providing this workaround. Its been weeks since I was able to use iTunes and I appreciate your help. Now that the issue is resolved I am posting my symptoms to contribute to the conversation. Before running netsh, I had the high CPU issues with the AppleMobileDeviceService.exe taking up most of my CPU and I was unable to access the iTunes store. Thanks again!!

    By GraysonWolfe on Nov 9, 2011

  39. cgamble,

    I’m in the same boat still — I haven’t reinstalled Bsecure yet.

    By brmorris on Nov 10, 2011

  40. Tony,

    Yep, that’s right, once for each command, although some others have had success with just a simple command as recommended here: http://www.thebambers.me.uk/wordpress/?p=316

    By brmorris on Nov 10, 2011

  41. I want to add my voice to the thanks for this post. netsh winsock reset fixed the high CPU utilization by applemobiledevice.exe for me too.

    By Doug on Nov 15, 2011

  42. BSecure here too, removed all worked. Sure hope BSecure (and others) can come up with in interm fix until Apple gets it together. Glad I found this article.

    By Wes on Nov 15, 2011

  43. I’m thinking that BSecure *can’t* make a workaround, this iTunes bug is due to exactly how Bsecure does the filtering..

    By brmorris on Nov 16, 2011

  44. I’ve experienced all of the same problems. I’ve reset netsh winsock, uninstalled and reinstalled itunes and no matter what I did – nothing fixed it. I then googled the problem in conjunction with PC tools anti virus software – and hey presto – there is a problem with their previous version of the anti virus program. Just uploaded the latest version and all problems fixed. Even my PC usage which was hitting 100% when I was launching itunes is now down at 4-10%. There is obviously a conflict with some antivirus software as we all seem to be having the same problem albeit with different protection in place. Hope this helps someone as its driven me nuts for days! good luck!!

    By Mark on Nov 17, 2011

  45. I have been having this problem for weeks. Tried everything, uninstalled and reinstall itunes 3 or more times, did the winsock and other reset but all to no avail. I finally managed to get on to the itunes store after I unstalled my PC tools anti virus software – thanks to Mark. But as soon as I reinstalled it I got the itunes store white screen of death. But that at least isolated my problem. I finally googled “PC tools interfering with itunes” and discovered that there was a need version of PC Tools internet security software. I updated it and bobs your uncle!! I foolishly assumed that given I have automatic updates turned on that I would get the updates! Nice one PC tools – nice of you to tell us that the old version was not compatable with the new version of itunes!!! No thanks o PC tools but thanks to Mark I seems to have fixed my problem after hours of trying to resolve it.

    By catec on Nov 20, 2011

  46. Catec, pleased to hear it helped. Like you, I had auto updates turned on for PC Tools but apparently it doesn’t load up the latest version automatically! I am still accessing itunes Store without a problem so it was definitely an anti virus issue.

    By Mark on Nov 20, 2011

  47. resetting winsock with the two suggested commands and then rebooting worked for me – THANKS!

    By Kendall on Nov 29, 2011

  48. Yes, this worked me fine as well. Thanks for the post, I guess you solved many people’s problem. After putting the command ‘netsh winsock reset’, restarting the PC, now it works well, no 100% CPU usage. Thanks!!!

    By Kate on Dec 10, 2011

  49. Did the netsh winsock reset. It ended the CPU high% however my CA antivirus asked me something about scanning emails I likes yes without thinking now I get a RPC error and my computer restarts every 5 minutes

    By Jay on Dec 12, 2011

  50. The netsh winsock reset
    netsh int ip reset c:\logfile.txt

    Worked great for me without a problem and solved the problem after a reboot! Thanks Much!!!!

    By steve on Dec 16, 2011

  51. Thanks, Steve! Your tip did the trick on an 8+ year old PC running Win-XP

    Execute the following commands at the cmd prompt; the first one may take a while to complete:

    netsh winsock reset
    netsh int ip reset c:\logfile.txt

    By Dan on Dec 17, 2011

  52. Safeeyes has the same issues as BSecure – winsock reset “solves” the problem (because it deactivates the Safeeyes LSP, then on rebooting Safeeyes notices that its LSP needs to be reactiviated, confirms that you wish to do so, and the problem returns.

    So we now have to have one PC for iTunes that the children cannot use!

    By Brian on Dec 17, 2011

  53. Brian,

    That’s so sad that iTunes has made it impossible to use the most popular web filtering software anymore…

    By brmorris on Dec 18, 2011

  54. I can confirm Safe Eyes is a victim of this issue and what fixes iTunes breaks Safe Eyes.

    What I don’t hear anyone asking is this: why does iTunes suddenly break what has until now primarily been the domain of content filtering software?? What do they need access to that they didn’t need before now?

    By BrianH on Dec 25, 2011

  55. What a *shame* that Apple is not taking responsibility for this.

    By brmorris on Dec 26, 2011

  56. netsh winsock reset

    worked for me on Windows 7 32 bit on a Dell Latitude E4300. 50% CPU to basically nothing. Perfect!

    By Bryan on Jan 1, 2012

  59. removing besecure cloudcare seems to have fixed the problem with the apple service – its CPU usage has dropped from 99% to 0%, and iTunes will start now.

    I use whole house filtering with the DNS set on my router to point to BeSecure – I had intended to not use CloudCare at all, but discovered from BeSecure that at least one computer on my network must have CloudCare installed for responding to periodic license verification requests.

    So CloudCare will go back in, once iTunes is finished with my iPad.

  60. Thanks for the fix, it did the trick for me!!

    netsh winsock reset
    netsh int ip reset c:\logfile.txt
    reboot

    The fix worked for me today on a Windows XP machine that was fine until the latest itunes was installed on it so I could perform my iOS update. Everything is great now after the fix. Thanks.

    By StevenA on Jan 1, 2012

  61. David,

    I do the DNS filtering, too, but there are some things that DNS can’t filter that Bsecure does filter, so this is a big deal, as you show in your situation.

    By brmorris on Jan 1, 2012

  62. Hi Steve,

    I just wanted to thank you for posting your message about the netsh commands:
    netsh winsock reset
    netsh int ip reset c:\logfile.txt

    It helped solving my issue with applemobiledeviceservice.exe hogging my cpu and iTunes store only displaying a blank page. I’m on Windows XP SP3 using iTunes 10.5.2.11.

    Kind regards,

    Gerard

    Thank you very much!

    Windows XP…….”at a cmd prompt…

    Worked like a charm!!

    My iTunes is now ready for my new iPhone due tomorrow

  64. Just got this note from Safe Eyes tech support; have updated Safe Eyes and can confirm that the old issues are resolved:

    ###

    There is a new version of Safe Eyes available to download directly from our website. This update fixes the recent issue with Safe Eyes and iTunes. Once you download and install the update, you will be able to sync your apple devices and connect to the iTunes Store. Click on the link below to download:

    http://download.internetsafety.com/safeeyes/safeeyes-6.0.244-20111223.exe

    By Brian on Jan 5, 2012

  65. BSecure / BSafe have provided a fix for the issue:

    1. Ensure you have latest CloudCare software (https://www.bsecure.com/MyAccount/Login.aspx and click ‘download software’)
    2. Install this and then reboot (http://www.bsecure.com/docs/itunesfix.exe)

    Done!

    By Justin on Jan 6, 2012

  66. Just came on here to notify you about the SafeEyes update and see that you already know! I have just installed it and it seems to be OK.

    10/10 to them for working around iTunes’ bug, and 0/10 to Apple for being so unconcerned about the problems they’ve caused and providing no explanation as to why iTunes has started to create such problems and even why it needs to be digging around at such a low level.

    By Brian on Jan 7, 2012

  67. +1 on that, Brian!

    By brmorris on Jan 7, 2012

  68. Bsecure and iTunes CPU at 100%

    Just upgraded Bsecure and ran itunesfix.exe as Justin explained above. The problem is solved – thank you.

    Keep in mind that APSDaemon.exe may still cause your CPU to run at 100% but this is OK. It will release the processor as needed when other apps run. I set mine to run at low priority and wifi syncing ran just fine. Bsecure is a great filter which meant that I chose to give up itunes rather than allow our computers to be unfiltered. Glad that I can run both again.

  73. Thanks Steve for the post below. I cant Thank you enough. This not only saved my CPU being floored by this Nasty applemobiledevices.exe, it also solved my IOS 5 upgrade issue. I have a 3GS which just refused to complete the first step of backup before the upgrade. It will stuck in there for hours and hours. With the below fix, I could upgrade my 3GS to IOS 5 with no issues. Thank you, thank you, thank you!!

    “I have checked numerous forums for a solution to this problem and stumbled across something. I saw a couple of recommendations to disable your firewall and one to reset your winsock catalog, so I diag’d my TCP/IP stack and once I reset it, i could connect to the itunes store (i was getting system hang at “accessing itunes store”) and my cpu utilization for applemobiledevice was restored to normal. do these two commands at a cmd prompt. (you’ll need to “run as admin” in vista and win7)

    netsh winsock reset
    netsh int ip reset c:\logfile.txt

    and then reboot

    this won’t change any of your IP settings and should fix your problem. i had this issue on two separate dell inspiron 6400′s and it fixed them. good luck

  74. An addition to my earlier post, I have a Windows XP Pro Service Pack 3 and iTunes 10.5.3.3.

  75. Thanks to Brian for the SafeEyes! It fixed my problem that I was having! My laptop quit lagging and I was able to sync with my Itunes. AppleMobileDeviceService.exe was making my laptop run at 100% but now it’s running like normal. Thanks so much again! You rock!

  76. I struggled with the same on my Dell ATG D630 after installing itunes everything slowwwwed to a crawl. Based on above advice I clicked the mouse on the start icon, then in the start menu clicked on the run and get the “command prompt” then entered.

    netsh winsock reset
    netsh int ip reset c:\logfile.txt

    and then reboot”

    WORKED!!!

    Wow. I was so frustrated and as you can tell, I am no computer pro. My new iphone now has music loaded and my computer is playing music from itunes and cpu usage is minimal. No excuse for apple to not fix this problem!~Bad Apple!

  77. Covenant Eyes is 1000x more important to me than iTunes. If I have to uninstall iTunes and re-install every time I need to update my iPod 5.5 gen, so be it (not that often, but still). I’ll thank Apple for giving me more reason to love android and Amazon MP3.

    Fix your software Apple!

  80. all,
    I have been having this problem ever since I got my Iphone 4s. I didn’t have the problem with my Ipad 2 or my Itouch. I then upgraded all and from then on I could not use Itunes at all on my PC (Win XP). I am behind a firewall and have web filtering on. I ran the
    netsh winsock reset
    netsh int ip reset c:\logfile.txt
    rebooted my computer and low and behold everything is back to normal. Itunes just sucessfully synced to my Iphone for the first time in months. Have had no other problems with my computer. Looks like this was a winner for me!

  81. Joe,

    Make sure to check your filtering, what you just did probably disabled it.

  82. I tried the two commands above and restarted. my Cpu is still maxing out when it begins the backing up in itunes. I have a win 7 netbook and an iphone 4 and have not been able to update from version 4.3.3. I don’t have bsecure or Pc tools. Is there other software that is causing the spike? This is such a huge waste of time. Appreciate the help.

  83. Microsoft has a fix-it program: http://support.microsoft.com/?kbid=811259

    Thanks to the advice and leads here I was able to solve in an easy way (I am not a PC expert or pro).

  84. carla,

    I’m afraid that you will be stuck having to follow Apple’s instructions on this page to figure out what is causing it:

  85. The winsock reset worked great for me too. Thank you all for your help. I will bookmark Brian’s website in case I run into other issues down the road.

  86. I ran the  winsock reset and
    netsh int ip reset c:\logfile.txt commands & it crashed my machine!
    Windows would not start.
    Was able to run numerous check disks & recovery attempts & was eventually able to restore system to a previous point.
    What happened?
    (HP Pavilion dv6, Windows 7, 64 bit)

  87. M,

    I’m not sure why it would crash it, you might need the services of a professional now!
