Thunderbolt ports inactive after installing Little Snitch

Short description of the problem: the Thunderbolt ports inactive, but connected on OSX

The problem:

Following a recommendation of a "COMPUTER technician", I installed the demo of Little Snitch.

After installing it, nothing worked, no internet, nothing.  Since it's a tool like Firewall, I started to change the configuration of this tool, but nothing helped.

Soon, I discovered that the tool had a lot to do, given that love at first sight for the Ethernet card did nothing more am.

I ran the uninstall program provided by the creators of Little Snitch and then (to be sure) rebooted the macbook pro.

After the reboot, the thunderbolt ports (tried both) didn't do anything... they remained inactive.

When I try a wi - fi connection, which was working still, so I'm safe on this part...

But I really need to use my Ethernet card on the Thunderbolt ports.

However, in the reporting system, the crush of material it lists as "connected".

What I tried to solve:

the Library/Preferences/SystemConfigurations/NetworkInterfaces.plist

and list of preferences have been both removed... then restarted.

I rechecked all wiring problem, or nothing to do with my router home... I'm 100% sure that this is not a problem, I even changed the ethernet cable to be absolutely sure that this is not a wiring problem.

My home router ethernet port turns on and it is connected on Level2 for sure.

Remove all interfaces in network places preferences and their reconstruction did not help either.

Despite this, I was desperate to re - install Little Snitch to see if I could find no idea he solve the problem... but that did not help either.

I'm still stuck with two Thunderbolt ports that remain inactive, if anyone has any ideas?

  • vCenter stopped working after installing WSUS

    As I tried to connect to our testlab vCenter (vSphere 5) this morning, I found that it stopped working.

    After a little research on the Machine (64 bit Win2k8) I discovered that someone went ahead and installed WSUS on the same computer that is running vCenter.

    As ex-athletes vCenter probably stopped working due to a port conflict between IIS and vCenters Tomcat (the two default port 80), so I tried to change the Tomcat port in the server.xml file. But which seemed to have done nothing at all (maybe I have something wrong here, not much in tomcat).

    Because I don't want the whole machine setup and I had some problems in the past with WSUS running on non-standard ports, I'm looking for some guidance on how to fix the vCenter instead.

    Any suggestion on what/where exactly, I do need to change?

    Thanks in advance

    First of all, you can check the vpxd.log on the vCenter server to ensure that it is indeed a problem of port conflict

    There are several services that might be running on port 80. Outside of IIS, SQL server reporting services is quite common in conflict with vCenter server.

    You can use netstat-nab | / findstr/i 80 to check what service using the port. If it turns out to be SSRS, you should be able to disable the service safely.

    I did find an official documentation to change the port for vCenter after installation. But a solution would be to stop the WSUS service and start the service of vCenter server. Connecting to vCenter and go to Administration--> VirtualCenter Management Servcer--> Web Service Configuration and change the http port.

  • PC Pavilion laptop: no sound on Pavilion g6 after installing the new battery CMOS

    I have a Pavilion g6z - 1 d 00 CTO Notebook PC, model A2F43AV number.  It came with Windows 7 Home Premium, and I upgraded the operating system to Windows 7 Pro (64 bit).

    The problem is that I did not sound, either through headphones or the speakers even if the Volume is set at 55. I first noticed the audio problem after replacing the CMOS battery, as the laptop is 4 years old and he gave me intermittent wireless connectivity problems.  After installing the new battery CMOS, I noticed the wireless driver was missing and downloaded/installed.  Everything was fine except the audio.  Then I reset the BIOS but nothing there as the BIOS version is v.49, and it is the most recent.

    I have also downloaded/installed the driver audio and rebooted the PC.  Still, there is no noise.

    Finally, I have checked the audio drivers and the reporting system they work without any problem.

    What should I do next?

  • Re: Lack of data partition after installing partition magic

    Hi there I m after a little help.

    Yesterday, I installed a program called partition magic. The installation went without errors or problems, but then when I run the program for the 1st time I got a blue screen and my closed laptop. I restarted the laptop and uninstalled the partition magic, but now, I noticed that the data partition is missing. I tried to do a restore back to before I installed the partition magic, but it does not help.

    Any help would be great. Thank you

    Lee

    Hi Lee,.

    May I ask why you installed the partition magic? Installation of these programs is always a bit risky and should only be done if you really want to change some sheet music or something else.

    Have you already checked Windows Disk Manager? Go to control panel > system and security > administrative tools > computer management.

    You can see the second partition and might be hidden or something else?

    You use a USB-serial adapter?  Has been sending peripheral data when you start the computer to the top?  The device sending the data while the USB adapter has been being connected?

    It's probably a Windows problem.  If you connect a serial device (adapter USB-serial anytime or a build/PCI serial port at startup) and the device sends data, then Windows think that standard equipment is a mouse.

  • Boot problems after installing Vista SP2 (KB948465)

    I installed SP2 via update.  During the update process there was a power failure.  After that (I don't remember if it's immediately after, or if a few days elapsed) I had problems with the startup.  Initially, seemed the Startup Repair to fix the problem, but not permanently, and the Startup Repair had to be used repeatedly just to start.

    After a few times of what is happening, Startup Repair did not turn, and the PC wouldn't start.  After about 5 attempts using the decision-making power, sometimes choose the Startup Repair, sometimes choose to load windows normally, he did start.
    I immediately did a system restore to return my PC before SP2 was installed.

    After the restoration of versions prior to SP2, Windows Update showed that the SP2 update failed.  It was on 9 November.  As I need my computer, I didn't reinstall SP2 until I had finished this work.

    As I thought that the problem is probably caused by the power outage, on 10 September, I reinstalled SP2.  Windows Update show no SP2 as an available update, then I downloaded and installed the standalone update.

    Between the 10th and today, 14, Windows Update has installed more than updated.

    Today, I was unable to start for the first time since the reinstall SP2 and Startup Repair has allowed me to open a session.
    I tried to uninstall SP2 via update.  The first part of it seemed to work, but when it came to reboot, the PC stopped at the end power to the bottom of the procedure.  I used the power switch to turn the PC back on.  After startup, the PC told me that deletion failed.

    Then I tried the system restore.  Unfortunately, the first available restore point was post - SP2 installation.  I restored it for the point that is as close as I could.  I tried to uninstall SP2 again through Windows Update.  This time, I receive a generic error message immediately (less than a second) - it does not attempt to go through the configuration - restart the procedure.

    I haven't restarted my PC since then.  Most updates have been downloaded automatically, and the PC tells me that a restart is required.  I'm a little worried that I will end up with a completely insensitive PC.

    I use an Acer Aspire X 3200 with Vista home premium pre-installed.  I don't have a Vista disc.

  • My computer is completely messed up after installing the latest updates from Microsoft. I need help/ideas to make it work again.

    Vista Business Service Pack 2
    32 bit
    2007-12-office
    Acrobat 9 Pro
    Adobe Design Standard CS4
    Sony Vaio

    I installed the latest vista updates today.  Three "important"; an option.  The optional parameter was an update of bluetooth toshiba.  We were talking about "platforms" that made me uncomfortable so I went to Microsoft and after reading it, I decided - based on little understanding - it was probably necessary.
    Shortly after, Acrobat 9 Pro wasn't working anymore. The computer asked me to restart after installing updates, but I have done a couple of things, including some e-mail.  During the attempt to send e-mail until I turned off the computer, Outlook flash he has been restarted and then the icon to install flash and then I could come back and type until the sequence started.

    I turned off the computer and when I rebooted, it did not start.  I managed to get it started; I run scandisk; now, when it starts to get a series of errors from Adobe for various Adobe programs that I installed on the machine all seem related to the "Automatic Setup" (or boot, I don't remember exactly.  I tried to re - install Acrobat and I get an error message that the 'source' is not available, and to ensure that it is - despite me using the installation disc, so I guess that it refers to the 'source' in Vista.  Outlook does not start.  He told me to use scanpst.exe to analyze the .pst files, but they seem to have disappeared.  I have tried other products of office except Explorer who started without problem.

    I can't use restore because it says that the disc is damaged and needs to be checked.

    Any ideas are appreciated.

    Uninstall the update for bluetooth.  Never use Microsoft device driver updates.  To avoid this does not happen, you must disable automatic updates in Windows Update driver as follows: http://www.addictivetips.com/windows-tips/how-to-disable-automatic-driver-installation-in-windows-vista/.

    Go to start / all programs / accessories / command prompt and right click on command prompt, and then click Run as administrator.

    Type sfc/scannow, go and let it run.  It will scan and try to correct some of your system files.  If all goes well he comes complete with no corruption, it could not repair (if it has these post of corruption here or try to analyze it to find the problem or files using http://support.microsoft.com/kb/928228.

    While in the command prompt, type chkdsk /f /r and enter and let it run.  It will scan and try to solve any corruption or bad sectors on your hard drive and remove especially as a cause.  Who can release the OS to do a system restore or other recovery options.

    Do you know when this problem started (probably with updates)?  Try a system restore to a point in time BEFORE the problem started.  Here is the procedure: http://www.howtogeek.com/howto/windows-vista/using-windows-vista-system-restore/.  Don't forget to check the box to show more than 5 days of restore points.  If the first attempt fails, then try an earlier point or two.  NOTE: You will need to re - install any software and updates that you have installed between now and the restore point, but you can use Windows Update for updates.

    If the system restore does not work, do a startup repair, boot from the disk Installation of Windows Vista genuine (or one that you can borrow from someone) or a recovery disc.  Here is the procedure: http://www.bleepingcomputer.com/tutorials/tutorial148.html.  You may need to change the BIOS to do first the CD drive in the boot sequence to boot from the CD.  To do this, hold the screen that tells you the key F to push to enter the menu start or start of installation.  Push it quickly. Make the changes, save your work and exit.  Put the CD in the drive and reboot.  When you are prompted, press any key to boot from the CD.

    If you do not have a floppy disk, you can make a bootable recovery disk by using http://neosmart.net/blog/2008/windows-vista-recovery-disc-download/ with burning software like: http://www.snapfiles.com/get/active-isoburner.html and, of course, a blank CD.

    If this does not work, try to start in safe mode (repeatedly hit F8 key so that the start and go in safe mode with networking).  Then we will check some of your system files:

    If it does not, then thanks for posting any repetitive error message in Event Viewer on startup (Start / Control Panel / administrative tools / Event Viewer).  Here's how to use Event Viewer: http://www.bleepingcomputer.com/forums/topic40108.html.

    If this does not work, you will need to do a repair/system upgrade using the Windows Vista Installation disc authentic (you own or that you can borrow from someone).  Here is the procedure: http://www.vistax64.com/tutorials/88236-repair-install-vista.html as well as the upgrade from an earlier version of the Windows section of the following: http://support.microsoft.com/kb/918884.  Although this will not affect your data, settings or programs, you should always back up your data before you start just be on the safe side. If other procedures do not work, it is almost certain to work.  You can have a lot of updates to re - install (including all you need to remove service packs).  If the version on system with SP1 or SP2 preinstalled cane and the disc is an earlier version, then you will need to do a slipstream drive as follows: http://www.vistax64.com/tutorials/151606-vista-sp1-slipstream-installation-dvd.html.

    I hope one of these procedures can solve your problem.  If this isn't the case, after return and we will try something else.  Return message anyway so we know how it turns out.

    If none of these steps work, transfer your question in Forum Windows Update: http://social.answers.microsoft.com/Forums/en-US/vistawu/threads where the people who specialize in updating the questions will be more than happy to solve your problems.  Don't forget to tell them what updates you downloaded and installed, and what steps you have already done to try to solve the problem.

    Good luck!

  • Problems after installing KB978338 on Windows Vista SP2

    I met a problem after installing KB978338. The update installs without error or problem, but the system is extremely inadmissible after the reboot. The "\Windows\system32\config\systemprofile\desktop is not accessible" error, and the system is practically unusable. Normally opens the Task Manager and system seems inactive, but you try to start a new application from the Task Manager gave an error "hose is not valid.

    System is Vista Home Premium SP2 installed without any obvious problems before the update. Start the system restore and go back to immediately before the update of the results in the system back to normal functionality and responsiveness.

  • RESOLVED: Loop of reboot after installing new disks in RAID of PERC S100

    A customer has a Dell T110 (with a PERC S100 RAID controller) running Windows 2008 R2. The system has two disks: a reader not RAID (C :) running the operating system and a RAID1 drive (E :) sharing data with network folders.) We need to install again, larger disks for the RAID.

    I thought I could backup the data on the RAID drive existing (e), install new disks, built a new table in the S100 (VDM) virtual disk boot manager, boot into the operating system, create the new partition for the data replaced E: drive and copy the data back. This was not the case. After installing the new disks and the new array of construction (which is reported as "READY (R/W)" when starting, Windows starts all the way in "press CTRL-ALT-DEL to log". After two or three seconds, the system reboots. The same thing happens when I try to start safe mode. The system IS NOT automatically booted to the Recovery Console. He never seems to know that an error occurred and the system was not shut down normally.

    I booted into the Recovery Console, installed the drivers for the PERC S100 and run recovery to start without success. Also in the Recovery Console, I ran 'chkdsk /f E:\. ' (remarkably, the drive letter for the data drive remained the same), and no error has been reported. I also reinstalled drivers S100 of the recovery using DISM Console, but that changed nothing.

    I started to 8.1 Windows PE, installed drivers S100, formatted the virtual disk, copied the data which he, and everything works fine. The only problem is when I try to boot from the system drive (which has no problem) with the new installed disks.

    When I put the old records, the system boots normally with no reconfiguration required. The VDM to start automatically remembers the discs and the table. Nothing shows up in the logs event indicating that there was an error during startup. (Ntbtlog.txt) start-up newspaper, after several boots with the new drives in place, indicates that the system restarts at various times during loading drivers. There is nothing coherent in the startup log to indicate what the problem is.

    The only clue I have is that, during the startup, the VDM reports the virtual drive of origin as 'NORMAL (R/W)' and the new virtual disk as "READY (R/W)", but I'm not sure of the significance of this difference or if it suggests a solution.

    I can't find clues in all the newspapers about what may be the problem. If anyone has any suggestions, I will be grateful. I'll be especially grateful for the wacky suggestions.

    I ran it. Nothing appeared unusual. However, I does not solve the problem.

    I connect the new readers to the same SATA ports as the old records. When I connect one of them to the SATA port that had not been used as part of the original painting, the VDM S100 reported the original failed array, because readers were is more connected and showed the new table as a LOAN. The operating system then started normally.

    The trick, it seems that you should remove the old virtual disk before connecting the new disks on the same ports.

  • I read that AFTER installing a language pack in Windows 7, some updates must be re-installed. How do you know which?

    That is my question.  I just did a clean reinstall of windows 7 ultimate.

    Before I did the installation, I read that I should install language packs before much updates

    Because if a person installs language packs after the updates, the updates must be reinstalled.

    I tried to install the language packs first, but windows update wouldn't let me.

    So now I think that a lot of updates must be put back.

    I looked for a list or something, but found nothing.

    Can I simply rerun microsoft update?

    I have everyone here knows about it, I would be grateful for advice.

    It's a little tricky. One day that will put you in the position of being able to receive updates is KB3161608, but this one requires reinstallation after installation of the packs of languange. :/

    Since you will need it anyway, in this case again twice, here is the link:

    https://support.Microsoft.com/en-us/KB/3161608

    You will need it as a sine qua non:

    https://support.Microsoft.com/en-us/KB/3020369

    requiring him also a reinstall after installing a language pack. :/

    Windows Update won't let you even manually install until you set automatic updates 'Never find updates' and restart, if her search runs in the background.
