Unable to start Windows Firewall

I had this problem and I followed Balon's post and it's working again. I think it happened right around the time I installed Microsoft Security Essentials but I could be wrong.

I'm now back to Webroot Secureanywhere for my anti-virus/ anti-spyware.

CHeers alot.

Thank you Balon!

I just joined just to say thanks to Balon. Kudos to you!

its quite old thread so not sure if i will get reply but want to try it before posting new one, I followed the steps and wa able to start BFE service, but do not get internet access if I start the service, currently I have stoped it and posting this message...any clue?

Not sure if thread is still open but I was able to make the registry changes and get the BFE started however when I go to start the firewall I get the error message "Windows could not start the Windows Firewall on Local Computer. For more information review the System Event Log. If this is a non-microsoft service, contact the service vendor, and refer to service-specific error code 5. " Any suggestions? I saw some posts of other people needing to give additional permissions for Windows 7??? I also saw another registry download entitled
0677.mpssvc.reg???? Any help would be FANTASTIC!!!!

ok so i followed the instructions and when i try to start windows firewall from services i get "Windows could not start Windows Firewall on Local Computer." any help is appreciated.

Registered into this forum just to say Thank You.....

Thanks loads for the posts people. I made my own bfe.reg and firewall.reg from page 2 of this thread. I lost my firewall the other day to a Security Scan or some crapola like that viris I assume.
I backed up the registry first then ran the bfe.reg and then the firewall.reg file, restarted my comp and followed the permissions change, started the services mentioned and bobs your uncle...it worked, I was able to go into the control panel and turn on firewall without the error popup.
CHEERS

P.S. looks like lots of intresting reads throught out this forum..I'll think I will hang around a while lol

I've tried everything... Nothing works :[ can't start BFE.. nor firewall. From setting permissions... to scanning with malwarebyes... to useing "sfc /scannow"... nothing will fix it.

Hi there, my name is Balon and I am pretty sure I have the way to fix your problem.

IT IS SUGGESTED YOU BACKUP YOUR REGISTRY BEFORE PROCEEDING

Backing Up Your Registry

1. Go Here and download ERUNT
   (ERUNT (Emergency Recovery Utility NT) is a free program that allows you to keep a complete backup of your registry and restore it when needed.)
2. Install ERUNT by following the prompts
   (use the default install settings but say no to the portion that asks you to add ERUNT to the start-up folder, if you like you can enable this option later)
3. Start ERUNT
   (either by double clicking on the desktop icon or choosing to start the program at the end of the setup)
4. Choose a location for the backup
   (the default location is C:\WINDOWS\ERDNT which is acceptable).
5. Make sure that at least the first two check boxes are ticked
6. Press OK
7. Press YES to create the folder.

Registry Modifications



Download both the registry files

bfe.reg

firewall.reg

Launch and import them to registry

Restart your PC

Now,open RUN and type

regedit and click ok

go to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\BFE

Right click on it-permissions

Click on ADD and type

Everyone and click ok

Now Click on Everyone

Below you have permission for users

Select full control and click ok

Now,open RUN and type

services.msc and click ok

start base filtering engine service and then windows firewall service

For further assistance contact me here, I will be checking this thread every few hours, this worked for me and it should work for you too.

You saved me man, about a few months back I got Botnet or whatever it's called on my computer. and I did a full W7 reinstall, but for some reason Firewall didn't reinstall. Somehow my installation disk got infected. But was minor and stopped security from being reinstalled. So now my computer is secure again thanks to you!

Many Thanks Balon followed your instructions to the letter and hey presto all working again, Thanks a million
