Can't connect to shared folder

I have a PC that was attacked by a virus that corrupted the firewall.  I have since removed the virus using malwarebytes, combofix, tdskiller, ect.  After the removal of the virus the firewall would not start which is not uncommon now.  I just had to add registry entries for the BFE, Mpssvc, and share access, and give proper permissions to them.  The computer runs just fine now, I can access the Internet, I can ping other PCs on the network ect, but i cannot ping my own address or loopback address (127.0.0.1).  The reason this is a problem is because no other computer on the network can connect to a shared folder on the problem computer nor can they ping my computer.  This occurs with the Windows firewall turned off and no other antivirus or firewall even installed on the computer.  I have also reset the IP stack and tried a different network card.  I need to be able to share out a folder on this PC so any suggestions would be helpful.

Everything is being done from all Windows 7 PCs.

No the other computer can not ping the computer name either.  I checked the hosts file and it has not been altered to where it should not allow a loopback ping or the ability to ping the actual address of the computer.  Both PCs are statically assigned the same DNS server but obtain an IP address and gateway dynamically.

I would try running a sfc /scannow at a command prompt.

Yeah I definitely know how to share a folder.  Checked all that.  This is in a domain environment by the way, I did not mention that earlier.

Found a partial solution.  Windows firewall was the culprit, which i had disabled it within the control panel but the service was still running.  I disabled the service and can share and ping.  Now the only thing left to do is figure out why the firewall is blocking it even though it is set to allow file and printer sharing and ping requests in the firewall settings.  The reason for the question has been answered though so I will close the question.  thanks for the help.
