I've been hit by zeroaccess virus last week, it corrupted the internet connection and dns system.

I cleaned everything and everything is working fine except pppoe connectins, they fail with Error 720

I looked into solving this issue and found out dhcp and "tcp/ip netbios" services are corrupted.

I fixed dhcp services from another computer and it's working fine. But "tcp/ip netbios" service failed due to dependency error where it need "netbt" service to start.

I restored netbt values from another pc but when i try to run this service from command promp with:

net start netbt

i get this error message:

The service name is invalid.

Does anyone have any idea how to fix this?

My system is windows 7 32bit.

How did you repair from another computer? Did you try sfc /scannow? –  user3463 Aug 18 '12 at 8:48
I just restored the registry keys for DHCP service. I tried this with netbt but the whole service is not recognized as installed! –  morset Aug 18 '12 at 9:39
Did you see my question about sfc /scannow? –  user3463 Aug 19 '12 at 5:10
