Recently I encountered a computer that would not let me turn on the file and printer sharing in Vista. When attempting to turn on printer sharing, there was a message. Everytime I tried, I was giving a message that said something I can no longer remember. If I do, I will update this post.

Through a little work, I discovered that the Base Filtering Engine service was deleted. This was done by malware. The fix was easy enough. I just followed the instructions at the link below. It has registry files to repair the BFE service for Vista and Windows 7.

This would be a good place to also provide two other commands that can fix network problems. Both must be run as an Administrator.

  • netsh int ip reset resetlog.log
  • netsh winsock reset

Also be sure to use Kaspersky’s TDSSKiller because if BFE is missing, chances are good the computer has a rootkit or an infected MBR.
