• Windows has encountered a critical error and close in one minute

  Whenever I have reconnected my network cable, I get the error message "Windows has encountered a critical error and will close automatically in a minute. Please save your work"and another message,"Services and controller app has stopped working ".

  The computer is running in offline mode and in safe mode, but the lack of internet access is a little pain!   I am currently using another computer to look for solutions.

  I tried the system restore, but when it restarts, it says that it is not successful.

  I checked the log of the observer of events and event ID 1000 error which suggests that "services.exe" is the problem.  I ran Malware and anti virus scans and there is no problem in the report.

  I had a problem with the AV Security Suite fake Scam three days now, this problem has been fixed, but the AVSS stuff has been removed, but this problem comes from the time.

  Is it better to just to do the restore to factory settings option? It's extremely frustrating!

  Thanks for any help/advice anyone can give.

  
  

  Thank you.    I had a CD of "Install Drivers on my computer" Dell.  When I put that in, it listed the available drivers and I extracted the files on the network card driver and it reinstalled a new network adapter driver.   Have had no problems since last night when I did, so all it seems has (finally) been resolved.

  For me, the return of the AV SEcurity Suite malware download problem.  This has been the most problematic bug I encountered.    At the end of the day, a clean installation of Windows Vista seems to have solved this, and reinstalling the driver for the network card.   I have not elsewhere found the Web to REaltek site it useful as the link does not work (it says I don't have permission to access the download). When I contacted their support, they pretty much told me to do what it says on its Web site and, of course, it did not work.  It made me hunt for this driver CD.

  It makes me happy, I had these original discs of installation provided with your computer, saved me a lot of £s!

  Thanks again for your help.

• Wireless problem Post Infection - Windows has encountered a critical error and close in one minute.

  Hello

  I recently had my computer infected by the virus of the Ant-malware Doctor and I believe that it has been completely removed now. However, I think that one of its components attached to a driver of key computer or something and when I removed it I accidentally deleted this essential engine with it. So I can not access the internet for more than a minute. If I turn on the wireless, I connect but immediately the computer says: 'Windows has encountered a critical error and ends in a minute' and 'Service and controller app has stopped working and was closed ". I checked also further in my error reports and think that it may also have something to with THE COUNTER Service? It is difficult to correct the situation when I can't access internet from my computer, but I can use another computer and transfer the files needed to repair the damage. Also I have a product Id, but as Im not using my own computer (to which the Id is attached), I can't access to professional advice. But if someone here can help I would be very grateful. IM thinking of uninstalling Service Packs and reinstall them but I'm not a computer expert. Thank you in advance.

  Updated after you have everything installed Norton Internet Security on my laptop the scans detected some trojan infectios and I'm checking for more information and to remove all the. Also, when I've updated my Norton Internet updates no warning sign came on a mistake criticism or service and controller app. It seems that viruses are to blame for the problem and despite the using various anti-virus software and scan many times before Norton virus remained unchanged. It's possible lack of virus definitions updated authorized to do this as the internet connection difficulties made difficult to download updates lasted. Thank you, and if the problem doesn't go away, I'll re-post say.

• Impossible to activate permanent "network discovery and file sharing" in advanced sharing without turning windows firewall at the wide service.

  Environment:

  I have a workgroup Windows 8 pro PC with all updates from Windows update. The PC is connected via WiFi (home) to a router (the same thing happens if I am connected to the router directly via RJ45). It's my "private network (NAT). I have the Windows Firewall is enabled in its default configuration. I use "Windows Defender" as my protection\firewall of virus software.  "When I go to: change options for sharing different network profiles" under advanced sharing options. I try to turn on file sharing and network discovery in the private profile. It shows that "the private sector is the current profile. The radio button lights. However, when I go to the file Explorer / network I got the message ' network discovery and file sharing are turned off. " The network computers and devices are not visible. Click here to change... " I click to change, however when I click to change it keeps returning and gives me the same message. I then go in ""network control and Internet\Network and sharing Center\Advanced sharing settings " and the option buttons in private profile for the network discovery and file sharing are turned off."

  If I turn off the Windows Firewall. Everything works. I need to open a hole in the windows firewall for 2 applications was discovered and network file sharing. I opened rather not just blindly ports. However, if this is the only solution, what ports do I need open.

  The bar notification on the screen of the network in Windows explore said that discovery of the network and file sharing are turned off and click to change. After a right-click and by turning on the network discovery and file sharing, the notification bar appears again and said the same thing.

  I didn't have this problem until a few days ago, and the strange thing is that I am able to access other computers on the local network via the \\computername method. However, access my computer from other computers or devices miss you

• File sharing problem

  I have four computers in small office. Three see each other, the fourth XP invisable on a Windows network. They all have the same name of "workgroup". and file sharing enabled. I can ping other but cannot get windows network to see?   Number four computer is configured to share files, I ran the wizard several times to double check that the names are the same.  Any suggestion would be appreciated.  James

  You left out the part where you tell us what version of Windows is located on each computer. This is important.

  What follows is quite old, but still excellent, former MS MVP Malke boards:

  Here are the steps of general network troubleshooting. Just cannot apply to your situation, so just take the bits that are. It may seem daunting, but if you follow the steps in the links and suggestions below calmly and consistently, you will have no difficulty to implement your sharing.

  Excellent, comprehensive, but easy to understand article on sharing files/printer under Vista. Contains information about sharing printers and files, and the folders: http://technet.microsoft.com/en-us/library/bb727037.aspx

  For XP, start by running the Network Setup Wizard the on all machines (see warning in section A below).

  Problems sharing files between computers on a network are usually caused by 1) a misconfigured firewall or a firewall neglected (including a dynamic firewall in a virtual private network); or (2) inadvertently run two firewalls such as the firewall of Windows and a third-party firewall. and/or (3) do not have accounts to the same users and passwords on all computers in the workgroup. (4) tries to create actions where the operating system does not.

  A. configure the firewall on all machines to allow traffic to local area network (LAN) as being approved. With the Windows Firewall, it means which allows file sharing / print on the Exceptions tab normally run the XP Network Setup Wizard will take care of this for these machines. The only "witch hunt", it will turn on the XPSP2 Windows Firewall. If you are not running a third-party firewall or you have an antivirus with "Internet Worm Protection" (like Norton 2006/07) which acts as a firewall, you're fine.  With a third-party firewall, I usually set up the allocation of LAN with an IP address range. E.g. would be 192.168.1.0 - 192.168.1.254. Obviously you would substitute your correct subnet. Do not run more than one firewall. DON'T STOP FIREWALLS; CONFIGURE THEM CORRECTLY.

  (B) to facilitate the Organization, put all computers in the same workgroup. This is done from the System applet in Control Panel, the computer name tab.

  C. create the counterpart of the user accounts and passwords on all machines. You do not need to be logged into the same account on all machines and assigned to each user account passwords can be different; accounts/passwords just need to exist and to match on all machines. DO NOT NEGLECT TO CREATE PASSWORDS, EVEN IF ONLY OF SIMPLE. If you want a machine to boot directly to the desktop (a particular user account) for convenience, you can do this. The instructions on this link work for XP and Vista: set up Windows for the connection automatically (MVP Ramesh) - http://windowsxp.mvps.org/Autologon.htm

  D. Si one or more of the computers is XP Pro or Media Center, turn off Simple file sharing (Folder Options > view tab).

  E. create share as you wish. XP Home does not share the users directory or the Program Files, but you can share folders inside those directories. A better choice is to simply use the Shared Documents folder. See the first link above for more information on Vista sharing.

  F. you have the job of file sharing (and tested by exchanging a file between machines), if you want to share a printer connected locally to one of your computers, share of this machine. Then go to the printer mftr Web site. and download the latest drivers for the correct system. Install them on the target machines. The printer must be collected during the installation procedure. If this isn't the case, install the drivers and then use the Add Printer Wizard. In some cases, printers must be installed as local printers, but it is outside this response.

• NB200 - C000021A error and blue screen appears

  Hi people, I have the following problem with my notebook of mothers a Toshiba NB200 - 10g. Basically it was a virus or a virus a little these days. Downloaded avg and malwarebytes in the hope of resolving and it has problems but pop ups were still appearing and found virus.

  In any case today he will be present when starting to move the party to boot windows he's going to where the login screen would be the screen flashes blue for the blink of an eye and the C000021a error message comes back on unrecoverable system error and computer stops and restarts x 1000

  I have read a bit about this problem and seems to be down to the fact winlogon.exe will be missing or corrupted by the virus. I tried all different modes start safe mode, last config etc. known. My major problem is I have no usb key to load anything on and the laptop doesn't have a CD player, so my options are very limited. Next plan will have to be to take it to the store tomorrow and get them to run a windows recovery program, but the problem is that I end up having to lend him my laptop tonight. Is there something I can do at all? Tried F2 and f12 to get into the bios, nothing that I can change. No joy, tried f8 and all start different modes. Do I have other options at all?

  Thank you

  Just to add, by pressing and holding 0 and then let go when it switches is supposed to be to get it to reset the good that happens the HDD RECOVERY at the bottom of a blank page for a second about XP tries to start again? Seems a little odd.

  Hello

  Obviously, you can't do anything else as to reinstall the new OS.
  Maybe HARD drive recovery would still be available on the HARD disk. So try this HARD drive recovery.
  This Toshiba HOWTo might be useful:
  http://forums.computers.Toshiba-Europe.com/forums/Ann.jspa?annID=58

  If the recovery of HARD drive is not available, then you could try to reinstall Win XP using a disk from Microsoft as part of the USB key.

• Problem with Windows Media Player: "Server execution failed" and "files needed to display video are not installed or do not work properly.

  I have a problem with Windows Media Player on laptop Lenovo G780. My laptop is under warranty (bought a month ago), but technical support Lenovo told me that the Windows Media Player program is not covered by the warranty.

  And this is a problem:

  When I click on Windows Media Player - to about 0.1 sec I see it opens and closes the window and nothing happens.

  When I select a mp3 or wmv file and right-click with the option open with Windows Media Player - I get a message: "Server execution failed" - I checked that all services with 'Media' in the name are running.

  When I select a mp3 or wmv file and right-click with the open option with Windows Media Center - Windows Media Center opens with the message: "the files needed to display video are not installed or do not work properly.

  When I select a file mp3 or wmv and right-click with option open with Windows Movie Maker life - see the video

  I tried to turn / WMP and WMC - did not help
  Tried to run as administrator - did not help
  I don't see something suspicious under events

  What can I do else?

  Thank you

  I had the same problem and then by chance, I tried a video on YouTube and it worked for me. Here's how I went on this issue and solved my problem:

  1. go to the computer, then OS (C).
  2. you will need to open Program Files (x 86) and Program Files.
  3. go to Windows Media Player in Program Files (x 86) and open the folder.  Then, remove the wmplayer file.  You may need to work around the error TrustedInstaller.  I'll tell you that, in a moment.
  4. in Program Files, go to the same folder for Windows Media Player and select the same file again. Wmplayer.  Copy the file in another window open.  Copy ensures that if the question comes up again you can at least try to fix it again.
  This should be the end of your problem.  If you need to circumvent the TrustedInstaller question is how:
  1. right click on wmplayer and select Properties > Security > advanced > owner > Edit > other users and groups.
  2. Enter your username and then click on check names.  Click OK.
  3. close the dialog boxes as he has requested.
  4. open again the properties and click Security.  Select your username from the list and click on edit.  From there, select full control.
  This should give you full control over the removal of the original file for WMP and easily allow you to copy the other files (x 86) programs.
  Please let me know how it goes for your problem.

  Have a read of the link above re Vista file and printer sharing.

  Permissions/Share info is there as well.

  If you use Norton, McAfee, Trend Micro or Kaspersky I.S., make that file and printer sharing is enabled in THE Firewall (or LAN enabled, depending on how their Exceptions are formulated in their firewall)

  Read the information above.

• Windows Firewall 7. Disable and file sharing

  I have a program that is unable to work so that the firewall of windows 7 is activated. I tried to restore the firewall by default and repeatable to allow access to the program. I tried the more advanced options, and they still do not work. I have resorted to installing third party software firewall and this is, I discovered, I can not disable the firewall of windows 7 AND disable the sharing of files and network sharing.

  He is super bad design. I don't want a network share or sharing files on everything. What should I do in this situation?

  When I turn off the firewall turns these return options. I can always turn them off, but ever time I turn disable then it resets these settings. Is there a way to permanently disable such things via gpedit.msc for example

  Thank you
