Windows 7: Bit of an odd one.

Bit of an odd one.

Dear everyone,

This is my first post here and I'm here because I've drawn a blank trying to fix the problem that I'm having. I hope that I've posted this in the right place.

I had a call from a friend who was having problems with a Win7 Home Premium 64-bit machine. The internet wasn't working. I went over and took a look and couldn't get a connection to the router (no IP) via a network cable. I brought it back to my house, tried a connection via my cable to my router. I still couldn't get a connection. I put it down to a faulty network card and ordered a wifi card as a replacement.

I installed the wifi card and exactly the same problem occurred. Then I saw a popup saying that the firewall was disabled. I went to enable the firewall and got the following error:

Windows Firewall can't change some of your settings. Error code 0x8007042c.

I've traced this back to the services.msc and have been looking at all the services to see what's wrong. I can't start any of the internet functionality because the Base Filtering Engine service won't start. When I try to start the Base Filtering Engine I get the following error:

Windows could not start the Base Filtering Engine service on Local Computer. Error 2: The system cannot find the file specified.

I've done all the obvious things - checked my Hijackthis log, run TDSSKiller and Rootkitrevealer (which wouldn't run), run Malwarebytes anti-Malware and Superantispyware in the hope that it might be a virus. I've uninstalled AVG Free 2011 which some websites suggested might be at fault.

Can I simply copy the missing files for the Base Filtering Engine from another Win7x64 PC, and if so, what are they?

Does anyone else have any suggestions?

Thanks for your time.

Suggest you run sfc scan couple of times.

SFC /SCANNOW Command - System File Checker

Not sure what files are corrupted

have a look at running the system file checker

SFC /SCANNOW : Run in Command Prompt at Boot

hopefully this will correct the error

Thanks for your replies. I have tried that. Does it make a difference if you run it more than once?

It may. SFC may not be able to repair everything in one pass, so its advisable to run it 2-3 times.

If that too doesnt help, the only thing short of a clean install is a repair install.

It didn't tell me that it had found any errors on the first pass, but I'll try it a couple more times and then try the repair install.

I would also try running at start-up, as shown in the link I provided, as this will sometimes pick-up problems not seen with a run within windows
