The Base Filtering Engine Service failed to start

Jul 19

When attempting to start the Base Filtering Engine Service in Windows Server 2008 R2 the following Services fail to start with a dependency failure or access denied error.

The following services may fail to start:

IPsec Policy Agent (PolicyAgent)
Windows Firewall
IKE and AuthIP IPsec Keying Modules
Internet Connection Sharing (ICS)
Routing and Remote Access

These services are dependent on the Base Filtering Agent Service, so they will fail as a result of any issues as a result of this dependency.

The Solution

Step 1: Log on to the Server with a user who has Administrator privileges and Click the Start button then select Run...

Step 2: Type regedit into the run prompt and click OK as shown below to open the Registry Editor:


Step 3: Grant full permission to the NT Service\BFE account on the following Registry Key: HKLM\System\CurrentControlSet\Services\BFE

Step 4: Finally ensure that the following subkey is inheriting full permissions for the BFE account: HKLM\System\CurrentControlSet\Services\BFE\Parameters\Policy\Persistent

Hi Ken,

Can you confirm you are using windows server 2008 R2? Also can you clarify in detail what the issue is you are having?

Is it finding the BFE account when adding the permissions or finding the registry key?

Hello, I am stuck on the same issue as Mr. Laumann.

I am stuck between steps 3 and 4, am in the Registry Editor, but do not see a way to Grant Full Permission to BFE.

Also, I clicked on the Parameters file, but only see default and service named files.

Any help would be GREATLY Appreciated!

Actually, you should be assigning "Query Value", "Set Value", "Create Subkey", "Enumerate Subkeys", "Notify", and "Read Control" instead of full permission. Also, the BFE service can be deleted by a virus, make sure you have removed it before attempting to restore the BFE service registry entries.

Dear Moshin, have you checked your system for viruses? I suggest using malwarebytes as well as AVG. once cleared follow the steps again.

Nope, you need full control. I tried doing just the handful of permissions Brian2000 suggested but it didn't work. Full control worked great though.

I cant find any user in NT Service.. Actually I can't find NT Service at all... :|

After I added the permission to the "BFE" key, I had to open up the permissions for every subkey, click advanced, and check the box labeled "Include inheritable permissions from this object's parent". As soon as I finished doing that, the service started right up.
