"Base Filtering Engine Service" Not available in services database list...what do i do and how do i get it back? RRS feed

  • 問題

  • So.....I recently started up my computer and got a error telling me that it could not find (or use) the following services:
    The Base Filtering Engine Service, The IKE and AuthIP IPsec Keying Modules Service and The IPsec Policy Agent Service. I tried to start/enable the IKE and AuthIP IPsec Keying Modules and IPsec Policy Agent services but both of them said that they were ether missing or unusable. But then when i tried to find the Base Filtering Engine was nowhere to be seen nor found. question is....what happened to it and how would i get that service back? I am really hoping to do not have to reinstall Windows....because i have a lot of data that i would rather not have to go out and by a External HDD and then backup all of the items that on are this laptop.
    Please let me know what to do.

    No dude. No one has given me the answer yet. I wish i could help you...but i am still having a issue with the specified service being missing from the service database. The only thing that i can think of is to reinstall my whole Operating system. Unless someone out there knows a different and easier way to do it. Can someone please help us out?

  • Win 7: I am having exactly the same problem. Tonight I tried to install Norton anti-virus, and the install failed because I have no 'base filtering engine' - the error message link said that I should contact Microsoft.

     I checked the serives list, and the base filtering engine service is not there. I've had problems with the 'win 7 home security 2012' virus lately, and I am wondering if that virus may have deleted the base filtering service?

    Anyway, would sure like to know if there's a simple way to get the base filtering service back without running a restore.  Thanks!

  • Hi,


    According the issue,  I recommend that you could use “sfc /scannow” to check the system file first.


    If the issue occurs again, I suggest that you may use the following method to create the service:


    Method 1


    Use sc .exe to create the Windows Service. Sc.exe uses the following syntax:

    Syntax1 (use Syntax1 to run Sc.exe)


    sc [Servername] Command Servicename [Optionname= Optionvalue...]


    Syntax2 (use Syntax2 to display help information, except for the query command)


    sc [Command]


    Please refer


    Method 2


    Also you may backup the Registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\BFE from another computer of same operating system .Then copy to your computer and restore the Registry.


    Hope that helps

  • danma_...I just wanted to say "thank you" for posting this information. I was having the same problem, and this was a quick and easy solution that didn't involve reinstalling Windows. Great info, and I appreciate it.

    To the others who are encountering the same issue, I can verify that this solution DOES work.

    Thanks again! :D

  • For some reason when i click on the links and download the files, it saves them as txt document files. If that is correct then how do i import them into the registry.
    2011年12月22日 下午 06:31
  • You can rename them to .reg. Or create another BFE2.reg file and copy/paste the content from .txt file to .reg file.

  • Copying the BFE service registry keys from a Win 7 Ultimate 64-bit to Win 7 Home Premium 64-bit machine worked for me.  I also had to grant Everyone full access to the key in the registry in order for the service to start, despite the permission matching that of the source machine (i.e. all the inherited permissions matched).

    I believe the BFE service's key was deleted by malicious software that I just removed from the affected system.

  • Trade of Jacks:

    Although I finally decided to restore the factory OS, your experience and solution sound right on.  Before I restored, I was able to edit the Registry to get the BFE to re-appear in the services list, but was unable to start it. That's when I gave up and restored, figuring that something I'd inadvertently done to the Registry might be causing the BFE permissions problem (i.e. a self inflicted quagmire that I didn't have the patience to resolve).  After reading your comment, it makes sense that the 'Win 7 Home Security 2012' virus may actually have deleted the BFE service key altogether, or at least edited its permissions.  Simply adding it back (or editing it, if it was still there) to grant full access would have saved me some work. I'll remember that for next time (although I've beefed up my security so much that I'm counting on there not being a next time !).

  • danma, 

    I've the problem described above (BFE service doesn't exist) on my Win 7 Ultimate/32 bits system.

    Please, post your answers to the following questions:

    1. Do the links (to the you posted can be used for my system version - Win 7 Ultimate/32 bits ?
    2. In my system32 folder exists the file BFE.DLL 483 KB. Is that file enough when solving the BFE service problem,
        or other files are also needed?
